Hello Everybody,
I'm attempting to restore my great-uncle's 915 Voice of Music console, this thread will focus on the 6v6 PP amplifier, and maybe branch off into the pre-amp as well. Visually the 915 is identical to the 815 shown on this page; the only difference seems to be the addition to an AM/FM receiver in the 915.
The console was the first thing my great-aunt and uncle purchased after they got married; adjusted for 2013 dollars it cost over 3K and was moved from place to place until my great-uncle gave it to me last week.
I have no previous experience with antique audio equipment, but I follow directions well =)
Progress log:
12/25/12-Get console home, blow out dust, contact Gary Stork at voiceofmusic.com for manuals.
1/4/13-Pull amplifier from console, remove and store the tubes, start to figure out what caps to order
2/10/13-Replaced filter and signal caps, unit will not power on
4/15/13-Purchased identical amplifier and pre-amp for troubleshooting
5/15/13-Replaced filter caps in second amp, second amp and pre-amp power on, unit sounds "ok"
Resources:
Schematics of the 6v6 power amplifier from the VoM 812, 912 & 815 consoles
Schematic of the Pre-amp that came with VoM 912, 1001 & 1002
Question #1-Schematics show the image below for capacitors, I understand I will be replacing the filter (can) cap with 4 individual caps on the underside of the chassis, but for C3, c4, c5, c6 what voltage should i be looking for?
Question #2-I understand there are different types of caps, and brands as well; what types and brands should I use?
Best,
Danneskjold
