Hi
I have a PL400 series 1 with XPL 910 outputs, two of which appear to be fried. I have purchased an installed the White Oak Cap replacements and purchased, and not yet installed, the watts abundant speaker protection.
I understand that one needs to replace all the transistors in one channel , so is there a suitable substitute ( these are darlington transistors),- both the fried were on the same channel, and all drivers transistors (RCA) test OK.
alternatively if I install the white oak PL14 replacement board and the white oak backplane board, what outputs can I install?
I used to have one of these back in the day, but this is the first one I have worked on- and my first post here
Thanks in advance for any and all assistance
btw the amp has a "diane" sticker under the PL14 board- what is this?
