Guitar and Amplifiers / Power NPN transistor for an amp, but what is it?
« on: March 28, 2016, 06:41:28 PM »
Hi Gang,
I got a few of these really cool NPN power transistors to build a nice power amplifier Ive been rattling in my mind for a few months. Really old but they test fine on my transistor tester and there gold plated too, lol.

What is very odd is the number on them is not on the net at all! I mean no where. Ebay, alldatasheet, alibaba, ext, really no where. Maybe some of you may have come across them? They look like they can handle a few amps but thats because they are in a TO66 package. They have a gain of about 80 or so and are BJTs from the early 70's. On the top is a cryptic number U6X and then under it 15H. There is what looks like a part number on the side ZA1023? Heres a pic

Oh well, if anyone has ever used one, from that time and/or are better tranny guys than me and may have a spec sheet or just seen it, please reply. Thanks!!

Hi All and you too Radio Tech as well. I've been here a few times, and decided too introduce myself today and hope to come back more. I saw many of your youtubes RT and clicked on the link in one of them recently to check this site out. I did not know It was yours and so glad that it is. Your youtube's are awesome as I have said. Am I mistaken in that your name is Buddy? OK, now a bit about me.

I have been mostly a computer geek for many years but have been into electronics since the late 60's. Worked at a few electronic like company's with transistor and early IC components (tech and design) but got into software for most of the late 80's and into the rest of that time until I had a stroke a few years ago and decided to retire early. Seems my wife and the doctors said I had too, oh well so I did. Took a while but back into just getting back into it. Electronics that is. No too much software though, just building and fixing stuff again and loving it.

Started to look closer at antique radios lately, got my tech license back a few years ago (never was really a big RF man) but got my degree in the electronic field in my 20's and just enjoying (NOW) getting into older (more fun) tube like radio equipment. Wanting to up my radio knowledge a bit now as well. Want to get a general class soon also and try a bit more of the Ham areas.

Just happy to play around with anything that has legs a bit bigger than surface mount invisible components like older transistors and now vacuum filled glass bulbs... haha!! Still love chips but a 12AX7 does hold a feel of fun for me because I play a guitar, love that old tech, and it truly does make a difference with sound.

All in all, pushing electrons has been in my blood since childhood, with many labs or benches or (shacks lol). Radio now has my interests along with Ham stuff and glad to be here and hope to share stuff with you guys and gals. I like to think of myself as an all around lover of this technology but now, a newer appreciation for the awesome stuff that has been built in the early days. I hope I can contribute as much as many of you has given here and elsewhere.

(Live long and prosper)  \\//
