Hello,
New guy here, in need of some help to recap an old Randall Commander II (RG 120). I hope one of you fine fellows will be able to provide some insights.
I've opened the amplifier and looked in. It's been serviced once (as mentionned by the seller) : some 7 watts resistors have been replaced by newer cement ones, because one of them had obviously burned (nasty burn mark on the PCB). All the caps seem to be original (with the expected amount of oxydation on their leads and solder joints).
So I was a bit puzzled when I noticed the two large filter caps have lower values than indicated on the original schematic : they should be 6000 mfd / 50 VDC but they're 4500 mfd ?!
Do you think that I should replace them with equivalent caps or switch to 6000 mfd as showed on the schem ?
Note that it's an Import-type amp. I don't think this is really relevant, but my knowledge in electronics has its limits, so I'd rather be careful than sorry.
