I'm looking for some information regarding PN 88650-60212 for my AC Amplifier in my 40th Ann.

I have found a few mentions that PN88650-60091 out of an HDJ81 is identical to FZJ80 part. I have found one to purchase from a reliable source for roughly 200 w/ shipping. Want to make sure, if I can, that these parts are interchangeable.

If I've missed as existing thread I apologize but thank you in advance for a link ;)

Can you post up a photo or two (both sides?) of the circuit board inside the box? Do you see any burned or popped components?

I'm stuck in relation to the AC amplifier for the Holy Truck:

88650-60171

Any information on interchanges would be very helpful.

@Engineer8000 might be able to work his circuit board magic if you are dealing with a problematic unit.

There will most likely not be an interchangeable part that would be a direct fit. There will most likely be wiring changes needed to install/use a different amplifier unit.

Thank you OGB. Much appreciated.

Thanks again for your suggestion, OGB. Engineer offered valuable advice.

Just for general knowledge, these things are pretty damn similar to each other even thought mine is off a Middle East Truck with a rear AC unit.

Here is the Unit off the truck:

Here is the unit I can readily find in the salvage yards:

The printed circuit boards are identical. The 60171 board just has a few more components installed. We will try moving a couple of components suggested by Engineer from the 60080 to the 60171 board.

I am so grateful to this forum....
