"i dont know what version of model 88 you are talking about the one i repaired doesnt have a coin battery in it!!!!!!!!!!!!!!!!!!!!!!!!"

As stated: Model 88CD has the battery mounted on the front panel, it supplies backup B+ for the RTC. The battery is a PCB mount, soldered in circuit.

RE: Solder Issues.

I have repaired many as well, 88 and 88CD. Not one had any cold solder issues or bad capacitors. There are only three PCB's in the 88CD.... top control board, front display/IR/control board, rear power supply/amp board and a woofer midsection. Perhaps the chassis serial run that came in for repair didn't have soldering issues.
