Searching (no luck) for T03 style replacement
(OP)
Hi all. I'm repairing an audio amp. The output devices are T03-can F15N and F15P. No other markings, date code or anything. I've searched the web with no useable results. I guess 3055's & compliments would probably do, but I'd like to do a proper job. Any takers?
Thanks, Steve.
Thanks, Steve.

And the power output.

you can afford to select more expensive,better part
so try to pick as close to ideal specs as possible.
You have to satisfy the owner and not some abstract specification -- it shouldn't be hard.

2SA / 2SC are fast PNP & NPN BJT's respectively
2SB / 2SD are slower PNP & NPN BJT's respectively
2SJ / 2SK are P channel & N channel FETs respectively
What brand is the amp? SCRs seem a strange component for the average audio amp to be using.

Maybe these are markings for matched pairs. In other words, each amplifier off the production line would have a pair with the same xx number: FxxN and FxxP. Maybe... maybe not.

It seems the brand and model of this amplifier is still a secret.

It's a Musical Fidelity, "Elektra E100".

In the meantime... I've found out that they are just good ole' bipolars. I've ordered some MJ15024's & 5's. I'll check them on the 'scope. If they look ropey I'll try MJ21193 & 4 (but they're over £6 each). Thanks for the comments; wee'll see how it goes. Steve.
