The boards I've seen use generic chips. That is, if you can take a photo of the chips showing the marking/lettering, one of us can tell you what/where to order replacements.

As to whether or not the chip(s) are your problem is above my pay grade - I'm not an ASC tech.

The chips are generic chips, the FET's in the boiler board are the same ones used on the PS/2 boards, and there's some resistors and a cap or two. There are also a few diodes on the boiler board, looks pretty standard to me.

Boiler board IC, bog standard LM339.

Tender board IC, another bog standard chip, the LM393.
