🎸 Welcome to my channel! 🎸

Hey, it's Ken here! Today, I'm testing different tubes on a Revv Generator 120 across all channels—Blue, Purple, Green, and Red. 🎶

Using my Agile guitar with Fishman Fluence pickups, no processing, and a Mesa cab with V30s. Tried KT77s, 6550s, 6L6s, and more. Find out which combo stole the show! 🎛️🔥

Watch, listen, and let me know which sound you like best.

As I was saying to @marshalllespaulfan when I took this, I know almost no one is going to “like” this picture of his absolutely incredible 1940s #Stark model 9-66 “Dynamic Mutual Conductance Tube Tester”. I mean it isn’t a 1959 #LesPaul or a 1956 #Stratocaster, or even a poor quality #Jazzmaster copy! But I know there is a very special small group of amp-oholics and #tube junkies out there that will get a real charge (no #amp pun intended) out of this spectacular piece of vintage #electronic testing gear. PS you really don’t want to see the schematic unless you wear very powerful spectacles! 😆 #vintageelectronics #tubetester #madeincanada #vintagegear #guitar #guitars #amps #amplifiers #guitaramp #vintagetube #vintagegear #starkelectricalinstruments #guitarphotography #ampphotography #electronics

What Is Tube Testing Laboratory

For laboratory testing and experimentation, tube testing laboratory are used to hold smaller amounts of chemicals. Chemists frequently utilize test tubes to contain, combine, or heat small amounts of solid or liquid compounds, particularly for qualitative research and assays. Tube testing laboratory is gradually being phased out of normal hospital pretransfusion testing in favor of gel and solid-phase testing, as it is deemed less sensitive than more current methods.

We are a leading supplier of laboratory equipment, including tube tests, at Maeon lab to satisfy your needs. 

Tube testing laboratory

, on the other hand, is very much alive at immunohematology reference laboratories all around the world, which still use it extensively.MAEON Laboratories is a leader in tube testing for a variety of industrial, agricultural, water and fuel transfer, and residential product applications.

Awesome late 30’s Jackson ‘427-A’ tube tester! Powers up but I didn’t mess with it too much beyond that. In great shape! $40 #vintageelectronics #tubetester #jackson #fatrabbitky #thingswehave (at Fat Rabbit Thrift & Vintage)

Might have to get that box of old tubes out and do some testing! 😝 This old 50's Avo tube tester looks more like something out of Lost in Space! 🚀 #avo #valvetester #tubetester #vacuumtube #valve #mullard #rcatube #sovtek #electroharmonix #vintagevalvetester #vintagevalve #avovalvetester #lostinspace #1950's

Wow, it feels like forever since I posted a project thing...

Well, I’m still stuck when it comes to the Philco 39-45. Part of that is due to my test gear, which I always buy used, so it almost always needs to be repaired.

I’d already done some work on my Hickock 540 tube tester, but recently it had started misbehaving. It was giving me weird results when testing known good tubes. So today I decided I’d peek under the hood and see what might be going on. 

As you can see from the second pic, I’d already replaced one of the resistors on the resistor board, but another one (the 1.2k at the bottom) was reading 1.6k, so it got pulled and replaced. Next there was a sneaky wax-paper capacitor (5th pic) hiding under the resistor board. I hadn’t noticed it was there till now, but it was not in great shape. So I cut it out and replaced it with a new equivalent.

Lastly there was a 100k resistor that bridges the neon lamp that indicates a tube is shorted. This resistor was way off spec, which meant that no matter how good the tube was, the tester always showed that it was shorted. I pulled the bulb socket out and replaced the old one with a new 100k resistor.

I fired up the tester and now it seems to be behaving itself. So, I’ll get it back in place on my bench, then run through the tube compliment in the Philco 39-45 to just double-check that no tubes are bad. Maybe that will tell me something...

Stay tuned for more exciting parts replacements!

Just got this back from a friend whom I forgot I lent it to. It’s going to come in very handy in the coming weeks.
