Hi all,
i wonder if anyone out there has any info on this manufacturer and this power amp in particular?
The manufacturer is Audio Concepts and according to the label on the unit they were based in Kings Lynne, Norfolk, U.K.
The amp in question is the Legend P300 power amp, dating as far as i can tell from the early 80's (a sticker from "Securicor" is dated 11/8/83 being the giveaway here!).
I have googled unsuccesfully, there is absolutely nothing out there at all. There seems to be an American company now using the Audio Concepts brand name though.
One channel output stage has failed, taking out two of the 6 MosFets. Removing the faulty transistors improves things considerably, now only -6volts at the output (still no signal) instead of the full -ve supply rail.
Does anyone remember this amp and does anyone have any info, especially the schematic?
A couple of pics are attached.
Hopefully, Percy.
