Hi all,
I've got a rather old beastie here, a LAB Series L5 amplifier, apparently capable of some 150 watts of output power, with a shorted end stage transistor.
The transistor is an RCA type, with the following markings:
254 002C RCA CW 7923The last number no doubt indicates the production year and week of the transistor, but I can't find anything about this 254 002C type number.
Does anyone have a clue what the equivalent may be? The problem is that there's ten of these in all, and proper repair procedure requires that I replace them all, so "simply trying" a few likely types (such as the MJ150XX series) isn't really a economical option.
Thanks in advance, best regards,
Richard Rasker
