I’ve had a pair of very rare Sherwood Mono Integrated Amps in storage for many years after purchasing from who knows where. These put out 60 watts of audio from 6 – 7189s. I recently commenced the process of restoring one of these and have some questions but first will describe what I have done. Initially powered it up on variac over time to reform caps and got very faint audio output which told me the fundamentals were there. I began by replacing the main C1 Can Electrolytic with one from Antique Electronic Supply which fit perfectly. Bypassed other 2 Electrolytic cans with under chassis replacements. Due to the unusual (“valley”) design of this amp, there was plenty of room for replacement caps on the bottom side of the chassis even though overall the amp has a very low profile. Then, replaced all the caps one would normally replace in an old amp (mostly Orange Drops) and powered it up. Works real well and has a very robust sound. I next proceeded to address power supply issues. This amp does not have a rectifier tube (unlike the Sherwood S-1000 which uses a 5Y3). The main rectification in the 1060 is done by 6 diodes located to the left of the power transformer (see pic.). The voltage readings after this are very close to factory specs—so the diodes seem to be good. In addition, there is a selenium rectifier (M-7 on pictured schematic) which, according to the schematic receives 25 VAC from the power transformer and is supposed to put out -3h0V DC @150ma. It is getting 25 VAC in but I get a -15 volt reading on the output. Tis tells me the selenium rectifier is in partial failure. I have planned to replace the selenium (for obvious reasons) but am not certain what type diodes to use. I assume the 2 anode ends will be connected to the 2 - 25 VAC blue wires from transformer and the negative ends will be wired together and connected to the C2A terminal of the electrolytic and I may need a dropping resistor. Do I have this right? I don’t deal in diodes much and am lacking a bit in knowledge. Any help would be appreciated.
