We Ain’t No Engineers

We love to sell parts. Let me correct that. We love to sell the right parts.

We get calls from many customers who, after looking at our web site decide they can’t decide what to buy. That’s ok. We have some experience with parts.   They tell us about their equipment and what happened and what they think they need. But… they aren’t sure.

… four of us are ham radio operators with over 100 years of experience…

Now we have touched a lot of parts and equipment; four of us are ham radio operators with over 100 years of experience in that area. We’ve touched almost every piece of ham radio and test equipment made in the last 60+ years at some point or another. We’re pretty strong in the analog area and we even have one guy who has heard of digital and can talk some digital. We know a little about RF; both low and high power. Yes, we’ve burned up a few parts but we’ve probably successfully repaired more equipment than the average shmoo.

So what’s the problem? Well, we probably can fix the broken equipment but it’s hard to do over the phone AND we don’t know what was going on when it died AND we can’t use all our senses and test equipment to evaluate what’s ‘on the bench’. You the customer must do that. Also, there is the time thing. Someone once said “time is money”. We cannot troubleshoot your equipment on the telephone. We do not repair equipment, other than our own. Another problem with asking us to troubleshoot over the phone is, what happens when we are wrong. Now you purchased a part that we recommended and it didn’t bring your equipment back to life. That sets up a bad situation that there is no happy ending to.

Get some help. Seek another opinion from someone who’s on the scene and has some knowledge. More information is available online today that can assist with almost any repair. Contact the manufacturer. Study the manuals. They say that people who ask for advice are seeking an accomplice. That may be true but additional insight almost never hurts.

I am personally a cheapskate. If I can fix it at no cost I’m there. Many times that’s not possible so I have to buy parts. I do so cautiously so as not to buy parts I don’t need… just like you.

Many times we get calls about parts that we don’t have because they were specially made one time only for that piece of equipment. Just because we have boat loads of weird one off parts does not mean we have the part you need. Sometimes, you can only get those parts from the manufacturer – if he still has them in stock for the thing they made 30 years ago.


Sometimes the calls are about parts the customer can get from the manufacturer and the parts seem extremely high priced. It may be because they were expensive to make and/or the manufacturer controls the supply and has priced them accordingly. These parts are usually marked with cryptic part numbers that don’t relate in any way to the value or function of the part. Sorry, but we can’t usually help with that.

Sometimes that piece of production equipment was made a long time ago and now that it’s broken it’s time to replace it with something that can be repaired.

These are all economic questions that can mostly be answered by the engineers and, unfortunately sometimes, the accountants. You might even have to involve management.

Please don’t call us to try to place us in any of the roles just mentioned. Mostly what we know is our parts and sometimes we know what they’re used for.

Call us about our parts and we’ll tell you what we know about them. We pretty much put everything we know about a part on our web site but don’t be surprised if we miss a fact once in a while. We have about 100,000 parts (line items, not part count) on hand and listed on our website. Another 100,000-200,000 have been purchased, now sitting in boxes in our warehouse. Slowly, they emerge, as time permits, and get cycled through our system to bring them up on the website. It is of no use to call us about parts you hope we have, that are not found on our website. Watch and search the site often. It changes daily. Dozens of items are added and subtracted each day of the week.


Making Our New Surplus Sales Video – Pro vs. Amateur

Producing a video about your business requires multiple major decisions be made first. Chief among them is who to hire and what is the end goal. In the fourteen-month process we started from a GoPro strapped to my Giant Schnauzer’s head, bounced to an interview style fixed camera storyteller and made our way to a professional full service production company. Our choice was the latter and we hired Torchwerks to create our masterpiece.

Dozens of hours of footage of ad-lib interviews, b-roll footage and a dynamite narrative were woven into a seven-minute play-by-play video that describes what we do to a T. Seriously though, the crew nailed it! We agreed early on that nothing would be scripted. When you give total control to a good producer, they can tell a story that makes sense to them, notwithstanding the fact they know little about our particular business. They ask and answer fundamental questions about the business in such a way that I found myself glued to this 7:33 film while watching it for the first time. And second. And third. I didn’t want it to stop. They told me the normal attention span for such an informational video is 2-3 minutes. We took the risk with this extended version primarily to provide answers. I have no doubt that the subject matter was covered in a much more dramatic, less technical style than what we could have accomplished with Sirius Black and the GoPro. If left up to us nerds, we would have bored the audience into a deep sleep with part numbers, dates and useless information.

Mr. Ben Drickey, owner of Torchwerks, struck home with a note when I asked him if our movie had too much content. He reminded me what the Emperor of Austria told Amadeus Mozart when criticizing an opera he had composed. He said, “You have too many notes”. Mozart famously replied, “There are just as many notes as I require – no more, no less”. Indeed, I agree, our Surplus Sales presentation is as balanced as The Abduction from the Seraglio.

A big thank-you goes to Josh and Jennifer for their perspectives. I was not present during their individual interviews and was humbled by the stories they told. This year I have now survived 40 years in this wonderful surplus business and hope to last a few more. Each and every day is an adventure.


Made In The USA – Here To Stay Or Passé

Maybe it has more to do with the fact I know the quality of a US-made part is historically high. An import is more of an unknown. It’s not a coincidence that most of our millions of vacuum tubes are NOS (New Old Stock) , largely US with a handful of European makes. The ONLY parts we import, in over 200,000 line items, are a line of coaxial relays, a solid state relay, adhesive tapes and a few rf connectors. That’s it! Beauty is in the eye of the beholder… or maybe just the peddler. If the seller has US made products, chances are, his price is higher than for an import. If he only has imports, he will tell you they are just as good as any US made part. In particular, the subject today is vacuum tubes.

Most tubes dealers have had the opportunity to buy off shore valves, including Surplus Sales. Many manufacturers to choose from, Chinese, Russian, all of which will sell you their product branded any way you want it. Your brand, their brand or something new. Whether you have a US-made NOS or a new import, what separates a “must have tube” from one better off in the trash can comprises variations in raw materials, tolerances and workmanship. We dropped the imports and have had to do without a complete lineup as many numbers slip away to oblivion in the NOS world.

5U4GB’s have been hard to find for years. For Surplus Sales it is one of the highest demand high power rectifiers we have ever had. Most dealers today run prices from $30-$50 for what precious NOS stock they have left. I am happy to announce we have secured a portion of the last remaining government stock of Philips JAN 5U4GB vacuum tubes, manufactured from 1985 to 1987. This is arguably the finest 5U4 available today. US made for our military’s radio equipment, likely of Rockwell Collins manufacture. Due to the large quantity of this premium 5U4GB now available we can offer a price from decades ago. Starting at $24 with deep discounts to $15 each when buying in quantity.  Stock up now. Once our inventory reaches a preset level, the deep discounts will cease.

In addition to the great news on our Philips JAN 5U4GB, we have cut prices on all remaining new and removed 5U4’s to reflect a proper relational sale price compared to the Philips. This is a golden opportunity to stock up. Once these are gone, there will be no more!





What is a Transfer Relay?

Guest Writer: Bill True, WA9ASD

That’s when you get on a bus and buy a transfer so you can give it to your buddy to use to ride his bus to work for the cost of a transfer. Well, not exactly. If you Google “Transfer Switch” most of what you will find are AC power transfer switches. These are used to switch your AC power from the power company to your backup power source; generator, solar panels or battery backup. If you have a home AC generator your power company will require one and your local building codes people will have to certify it. It could be manual or automatic. We offer a Generator Transfer Switch. 

Is it a switch or a relay? The answer is confusing. My answer is as it pertains to Surplus Sales. A switch is a manually operated device.  Contacts are actuated with a twist or flip of a lever. It must be physically switched. A relay has a coil with a set of contacts operated by an armature. apply a voltage and cause a change in the position of the contacts. Switch: manual; Relay: electric.

Amphenol 300-11002-2 Transfer Relay

An RF Transfer Relay allows you to connect 2 transmitters to 2 loads. One to a dummy load and the other to an antenna. When the relay switches the two transmitters are swapped between the antenna and dummy load. Another way to look at them is to consider a 2 position switch with ports 1, 2, 3 and 4. At rest port 1 is connected to port 3 and port 2 is connected to port 4. When activated the connections reverse. Port 1 is connected to port 4 and port 2 is connected to port 3. Broadcasters use these to connect both their main and backup transmitters to the antenna/dummy load for almost instant changeover to the backup transmitter. It can also be used to control the antenna connection to a transmitter and receiver. In the “at rest” position the receiver is connected to the antenna and the transmitter is connected to a dummy load. By switching on the relay when the transmitter is activated the antenna gets connected to it and the receiver goes to the dummy load, protecting it from the strong RF from the transmitter.

Another kind of reverse (perverse?) usage is to provide automatic grounding of an antenna when not in use. Whenever the transceiver is powered-up the transfer relay is activated connecting the transceiver to the antenna. When the transceiver is turned off the transfer relay de-activates connecting the antenna to ground. The same thing can be accomplished with a knife switch for open wire feed lines.

We have a couple of very high quality “N” Transfer Relays available from some of the most highly regarded manufacturers; Amphenol, DowKey and Transco (now a part of Dow Key Microwave). SMA Transfer Relays by DowKey. C connector Transfer relays.  EIA Transfer Relays for the Broadcasters.  Waveguide style Transfer Relays.

As you can see, transfer relays can be an important and valuable addition to your station. Call us if you have any further questions.
