Anyone know good replacements or where to get the outputs for this amp?


They are::

B778

D998

I use the FJA4213 and FJA4313 as universal replacements for all of the various output transistors in amps like these. They are inexpensive, generally readily available and reliable. I have used hundreds of them and have never had any fail.

Wow, those p/n's look like the ones used in an ancient pyramid pb600g I used to have. Maybe off by one digit, lol

You may have used the 4210/4310.

Haha I was referring to the originals. The amp never died on me, I just had it opened to bypass the "bridge" switch.

Actually I think the pyramid had a b7something and the corresponding opposite. These to3P's appear to be like the ones in a newer kicker impulse amp or similar.
