I see. I knew it wouldn't be that easy but had to ask. I do not have a safe way to put this thin together and be able to probe the caps with it on to see what the voltage is. But the fact that there are 80v caps on this and there not blown up should mean its safe to use 80v i would think

What, you don’t have a multimeter?
That is not the statement at all. It seems that the system is built of modules and presently not assembled. Evidently the amplifier is a five=channel assembly of amplifiers. I had not considered that as the arrangement, and I can see where it would require quite a bit of dis-assembly before any module could be serviced. And evidently the intended repair scheme would be a parts-changer replacing modules, rather than doing any diagnostics and replacing a failed component. It requires much less technical ability.

Also u have to remove all five amp modules before u can remove the main rail cap board and final wiring from the system. Also u have to remove the transformers second to last. But even if I put it all the way back together the case is not on the lower side. Also I'm not crazy enough to turn this thing on laying on my desk.

Good thing I'm changing out all the caps. I pulled another amp board to upgrade the caps and pulled the 50v 220 cap location but found some one had installed 25v 220 uf caps in those spots. one of the caps has started to bulge on top

The damn ribbon cable linking both boards broke off at the lead tips on one of the boards. Also my soldering iron broke at the same time. Not sure Weller makes a good product

My experience is that Weller products are of adequate quality, but that ALL soldering devices are subject to eventual failure of some kind. Some products last much longer than others, of course.

Soldered ribbon cables at the PCB end are very delicate indeed, that is why sometimes the junction is supported by a bead of glue. For repairing it might work to install a ribbon cable connector pair instead of just re-soldering the cable. The "AMP"braand IDC connectors can be installed without needing a special (expensive) tool.
