:grin: What should I do with this thing?
I've repaired tube amps but never have designed before. This is going to be my first testbed for tube stuff. It's an old TV set I pulled off of the curb in front of someone's house before the garbage collector got there. :guinness: It has what seems to be a raucusly large power supply, lots of tubes and sockets, and oodles of giant wattage resistors and caps. I think the picture tube was blown, cuz everything else seems to work fine.
I'm just learning tube theory, using FET & bipolar (not manic depression) theory as a springboard. I know transistor theory pretty decently, excluding current sinks, on which I haven't found a good resource for study yet.
Where do I go from here? I'm interested in class A preamplifiers almost exclusively. Mostly mics & microphone signal chains. I also have waaaay too many audio transformers... :wink:
I have just drawn up my first basic tube preamp, and I'll probably be able to direct couple it if I want to.
I know there's enough info on this board to keep me going, and I'm almost at information overload every day on the Microphone META META... (Bowing in the direction of PRR and Gyraf)
I found a few links to work from:
