Jos,
I got into doing antique radio restorations when I graduated also. A mentor of mine who went to school with my mother, now would have been about 82 years old (sadly passed on), gave me his set of Ryder manuals and books as a graduation present. Before I stated my own shop, I worked for him full time about a year. He had a radio repair shop, and back then (1984), there was still a large amount of tube equipment around. I actually worked part time after school for him when I was 16 on till my shop. I met Ed Delaney through him who most know manufactured the D&A amplifiers. He was a ham, and an instructor at a correspondence trade school. His picture used to be in several radio magazine ads. I can't now think of the name of that school, but he lived in Nebraska. He talked me into getting into amplifiers along with Abe Brewer of Brewer labs. Most know what they manufactured without getting into that here. There knowledge was deep and sure did help with anything I wanted to know. Ed died not long after I met him, if I recall with cancer. I offered to buy the remains of D&A at one time from his widow but she wanted to much. I think she priced it at about $75,000+ and that was way too much money for somebody my age back then (1984?). It ended up going out to several surplus houses I heard. Anyhow, tubes were what I cut my teeth on.


I have an old "push button" Zenith B&W here I've kept as an antique. Push button back then was a Rube Goldberg contraption. To change the channels, you pushed in a big button on the cabinet where the tuner knob would have been. A stepping motor inside turned the 13 channel tuner. That was once touted as a major advance in television, Har Har! I still fire it up every now and then, but the caps are going to have to be changed as the verticle hold is starting to get screwy. I have an old Zenith floor radio here too I overhauled. It's one of the tall wooden ones from back in the late 40's or early 50's. To be very honest, I like the sound of the thing.

Besides RF amps, I like tinkering on tube guitar amps. I've had Marshall Plexis, Ampeg Porta-Flex's, Fender Bassmans, etc. all come through here from local bands and others. I've had request, on top of request, to get more distortion out of some. After working on them I generally get a free jam session to test drive them so to speak. I had a complete bluegrass band here at the shop one time. Needless to say, I didn't get much work dome but it was fun. I'm not able to do a lot with them now like I did, but sure enjoyed it.

The prices some are getting for these "new ones" is ridiculous. Tabletop models with the tubes showing just for the looks, are running at war prices. I've thought awful seriously in getting into these, but haven't yet, as I just don't see a market that well here. There's not that much to one to get a couple thousand bucks out of it, and folks are paying it evidently! There's a new tube tester available, specializing in audio tubes, and the price for it is ridiculous too! I know one thing, they can be built for about 1/8 the price and be sold for 1/4 of the going rate. There's some transformer-choke manufacturers stating theirs is better than others for audio quality, and you'll pay that quality price for them. If they're designed correctly ( for audio service), there shouldn't be any difference. One sales gimmick after another to get that extra buck.

Luckily,
While I was in Vo-Tech, our electronics training included tubes as much as semis. Our instructor was an avid ham and seen we were taught both. We had several tube type, television trainers made by Motorola on the bench. Plus, some tube ham gear there. We were taught home brewing also as we had a small, shear, brake, drill press, and a lathe. Not doing something then was no excuse. It's funny that I learned on those old tube Motorola trainers and then took over a Quasar dealership after I graduated. Remember the "works in a drawer"? Those used to be tube, tube-hybrid, then all solid state. I used to have a ball working on that


stuff and everything was heavy built, steel chassis. I had shelves of tube power transformers salvaged from Quasar, RCA, Sylvania, etc. sets. I'll have to say, Sylvania was the toughest, even in their first modular

sets. I remember in my first year of school, at the ripe age of 16. I had a 304-TL and a 572B in each hand and the instructor telling me he could get way more output out of the 572B. The physical size of the 304-TL (round) made me think it was larger in power back then =) All those days are about gone, and how much I've learned in the 23 years
since.

When I got into ham radio in the late '50s it was more common for transmitters to be homebrewed than bought, especially if you include kits as "homebrewed". Thinking back on all my friends from those days, not one had a commercially made transmitter.

Receivers were a different matter.  Nearly all were commercial or
modified war surplus, which there was a ton of back then.

Ahhhhh... the good ol' days. :-)
