Also, the 3A Filament Fuse should be a 4A slow blow. Cary printed the wrong value on the back of the unit. In the schematic for the V12R is confirms it should be a 4A slow blow.
The fuse is a 4 amp SB, now, had a 5 amp in it, I pulled all the fuses and replaced them. I've bias with a mono 1/4" male splitter with 2 RCAs hook one lead to the outside RCA and the other to the inside via a probe. That's when I learned 210ma sounds ok but 230-240 at lower volume is just as sweet as they come. I'm really liking 6L6 cheapo valves Solvex. Only valve that going from single to UL sounds better. I like the sound better for certain music, especially old country western, or big band stuff. Haven't heard anything that sounds bad other than a bad recording, got a few of those..
At 100.00 + an hour at Cary, I can do a little work myself.. Suppose to be almost bulletproof, amp, I need it..
I'd like to see the upgrades too, there are some clusters of diodes two sets of three that look to be hexfred, at least when I looked them up.
Is it a power supply upgrade? I had Samra do a C20 with Schottkys, PIOs, and a few Teflons. Quietest point to point, I've ever had.. and the most musical. Just no remote... I like a remote.
