Welcome to the forum.  How hard is it to find tubes for your hobby/past time?  I've always heard that tube amps are the mac-daddy, but have never been around one side-by-side to a good quality class-A transistor amp.

@js, Welcome to the forum! You'll find many members that are both willing and knowledgeable in electronics, and coding in C++, and many other languages as well. I look forward to hearing about your projects and of course your Tube restoration hobby. I was Navy Trained back in the mid 1960's in electronics when we were still mostly using Tubes.. I was an FT ( Fire control Tech, EWS, D.A.S.H., ASROC)  After the Navy I went back to School to learn more about solid state and computer science..Worked in heavy industrial electrical/Instrumentation for the next 45 years until retirement.

Great to see such people as yourself expanding their horizons and wanting to learn more..that's mostly what most of us are doing as well, and passing along some of our knowledge to others.

Welcome aboard..

kind regards,

LouisR

Indeed Tube Amps are the Mac-daddy , especially for audio amps..very good micro-phonics, and somewhat easier to troubleshoot as when the tubes go, so does the glow...lol

Thanks for the reply, I can still get tubes for Projects but getting harder to find. Exp. 5U4 Ret. tube.

As far as Solid State, I have a class AB----Pioneer SA 9600 that I have rebuilt.

Good ole heavy duty power transformer and linier power supply. It does not grunt when hitting the low frequency.

@inst-tech 

Thanks for the Welcome, I have learned Basic command prompts for Linux--Ubuntu and reading about C++ coding for Arduino, just another mind exercise for the hobby. I am also a Tesla follower

and working with high voltage @about 27khz to levitate small objects. I have a small lab complete w/digital scope, power supply and waveform generator.    

Hi JS,

I am also a big Tesla fan as well.

Welcome to the forum.

@inst-tech Yep, I have worked on some seat warmers, Ha. You can load Plates on tubes better than silicone collectors, I think. <>

hello Inst-Tech,

I am Rallard and welcome to the forum.

Have You heard of Uncle Doug? He is big on amp repairs.

@rallard No, I cannot say that I know <Doug>. Does he broadcast on you tube?

Thanks, Rallard, for reach out...

Welcome aboard

Hello @rallard,  No, I can't say that I have heard of uncle Doug..but then I haven't worked with Tubes since I got out of the Navy over 50 years ago...lol

@js, yep.. that's a 10-4 buddy... micro-electronics is another world where high current and voltage is the enemy...lol

I gota say now, I don't miss those "seat warmers" with plate voltage of 500 volts on our SPS-30 transmitter..got across one of those  2000 uF  electrolytic once when pulling out the power supply for maintenance check..forgot that shorting stick..didn't ever forget again!..lol

@sj_h1 Thanks, Man
