Greetings I own a 45 year old amp, AUDIOMOBILE SA-1000. Power transistor blown. Its a T0-3 type, "S" brand "SOLITRON" I think
Numbers on it are 0602016 8101
I cant find anything online, Uggggggg any help will be much appreciated, need new ones as well as some advice in regards to these blowing. My 45 year old amps are all working fine BUT this particular one. It ran hard for a while in my other car, but after it thermal shut down I pulled it but I think i hurt it. Been blowing output transistors (2) so far and now.... Power source is dead. This poor amp. LOL....
I just bought a couple more SA-1000's so I will have spares to blow up soon. Would like to get this one fixed.
Any help, THANKS!!!

Why not try the TO-3 PS FETs that Linear power used if they're bipolar transistors.
Remove a good one and measure the forward voltage of the B-E junction on diode-check.

Yes, a substitute may be in order as I am not finding anything spec related online. Damn. Power transistor made my LIGHT come on BRIGHT.... Thanks for that idea. One I think is OK and one is surely shorted. 45 year old caps and transistors. Uggggggg
I also been messing with a amplifier I bought that wont turn on. an OKUR brand. Still unsure of why its dead but I think its transistor based issue. Unsure. LEARNING is hard when ya in AGONY..... LOL.
Hi Perry, Theres four numbers at the bottom of this transistor "8101"... thats a DATE code, yes?. Might have found a replacement.... 22 bucks... OUCH. LMK BDBD/2022
Hi Perry, Happy Holidays to you. I suffered a fall and broke my back pretty bad... pain but I will live. I measured the "good' transistor at 557 reading on the diode check meter setting. No shorts on this one, the other one has an obvious short/BAD. Just went POOF!. I ordered REPLACEMENTS, on their way in the mail. Wondering if the power supply capacitors should be suspect for replacement simply for proper operation. Hmmmmm.... I check them with the capacitor checker meter and they read good. Good quality ELNA brand BUT they 48 years young so..... My aching back. LOL. Hope you are having a Happy Holidays time bud. Keep ya posted...
ALOHA BDBD 2022.
OH YEAH.... my PC DIED... Uggggg SO I scraped up the FUNDS to purchase a NEW one so now i can get to uploading the old Safari etc and then I will get your tutorial and start learning HARD.... Nose to the grindstone. I got some stuff to FIX, I am pretty much a cripple now... It's what I will be doing going forward. Be in touch. BDBD/2022
Sorry to hear about your back injury. Those can be tough to recover from 100%.

Go here to buy the original SA1000 and SA2000 TO3 transistors.
https://www.surplussales.com/Semiconductors/Transistors-SCR-1.html Their part number is (STR) 0602016 for $22.00 each. The date code is 8313 which were made the 13 week of 1983

and PERRY... I have that AMP you describe as taking YEARS to REPAIR.... LOL... I WILL find the problem... BDBD
