Anyone familiar with a Mitsubishi DA-R35 receiver or AR11s?
My system became unplugged for about 6 months and wont restart easily:
The receiver wouldn't start and just lay inactive for about three hours Everything was dead including the whole tuner section which was stuck at beginning of the register. No controls worked. Then suddenly it sprang to life and started working. I am pretty sure I didnt put any batteries in the compartment at the back to corrode but is this starting procedure normal? But then the AR11s (possibly about 20 years olf?) started giving problems: One seems OK but the other only gives a thin scratchy mid- range sound and intermittently at that. It sounds like dirty pots or whatever those controls are behind the three position switches? Or does this speaker just need new caps on the crossover? Does anyone know of any instructions on line to get at the cross-over please? (There seems to be a vintage speaker forum with lots of dead links on it) |
