I'm tired of anemic guitar amps!

Trying to get "there" to where I have room and tools to work on my amps. (Inspired by this thread.)

It will never meet toobfreak standards but that's a given for most of us.

Isn't it

Very nice! What's the gadget on the top left? Waveform generator?
Top shelf, left to right is Motorola Radio Communications analyzer, TechTronix 100mhz Oscilloscope with 1.3 Ghz frequency counter in top if it and a Agilent 1.3 ghz Spectrum analyzer to the right.

Under the shelf are two power supplies, HP digital volt meter and my Huntron Tracker model 1000 component tester (curve tracer)

The Motorola "service monitor" does have a built in audio signal generator, it's own spectrum analyzer, RF generation and Receive, encode, decode, cable fault finder (time domain reflectometer) and oscilloscope. Really handy in the field.

High frequency stuff. You work on radios?

Actually looks great! About as clean a work bench as I've seen. You have it all there, power supplies, frequency counters, an old Fluke bench multimeter, scope, LCR bridge, some other doodads, looks like you're pretty set to go!

That old LCR will be up for sale soon. But those things are pricey.
 
Yes for 30 Years until retired.

I have an original Ameco transmitter.

One of these:

It has a genuine 6v6 tube! :p

You plug a Morse code key in the back, and you need an SWR meter to tune it up. It's about 15 watts. I built it when I was about 10, it served me well till high school. Got to Australia with it, from California, on 40m with a dipole.

I seem to recall it was 29.95 when I got it, it's worth a small fortune on eBay now. The crystals are hard to find though.

I never got my HAM license.

I did have my FCC tech license that has since expired.

The internet (and family medical stuff) took away most of my want to go further as an operator.

You guys and your tube tech really got my curiosity (about tube amps) though.

There were some tube finals in some of the two way radios I started on (GE and Motorola, mostly) and there were giant tubes in the lasers and RF welders I helped maintain. . . so I was never too far from tube tech.

A few other things nice to have:
  1. A variable AC power supply.
  2. A variac.
  3. A frequency counter with Nixie tube display (for pure Ooooh Factor).
  4. An HP clamp-on analog ammeter that measures down to the nanoampere.
  5. A transistorized Philips analog display VAOhmeter with low-Z input and linear display (equal accuracy and resolution at either end of the scale).
  6. A Wavetek 2030 true r.m.s. testmeter with audio output to convert signal to sound.
  7. A Fluke 27 for explosive atmospheres.
  8. And last but not least, an original 1920 Westek Telco D'Arsonval ammeter.

I do have a variac and a rack mounted variable AC with hi pot testing. No nixie tubes.

I have a like new Simpson 260 and a decent true RMS fluke handheld.

All great suggestions though!

I have an AM radio upstairs from the turn of the 20th century whose speaker uses no permanent magnet, the radio itself fed a current through a core to energize it, the tuning cap is a multi-ganged copper drum about 6 inches in diameter and about 8 inches long, and the output tubes are not like any others I've seen (push-pull?), they have a smooth straight taper from the round top to the much narrower base, and the tubes then go into some sort of adapter to fit them to the radio chassis and appear to only have four pins each.

I tried to find a picture of a similar tube on the web but I found none. The tubes have a paper tag glued to each base apparently from the store that originally sold them and it has the same city on it as the radio itself came from.

These Oscillation tubes (used in RF welders) were about 8 inches tall. Maybe 10.

That sounds very valuable and collectable.

Those were classics! Indestructible. Really great tool for testing motors and other low-Z items, their only flaw being that the displays were logarithmic and lost resolution towards the tops of each range.

My Philips is odd in that it operates and looks just like a VAΩ meter, but it has a 20-meg input Z just like other electronic multitesters.
 
Just one more then I need to get to bed.

This was one of my repairs.

The wires burned and broke from the tube and I had to gently fix the wirs to the legs with small hose clamps. I also hand wound the newer looking choke, by counting the turns on the original.

LOL.

Fun times.
