I re-capped my '76 SFVR (non-master) as it had the following symtoms: 1) loss of power (had to crank it to 10 for it sound like what it did at 6) 2) loss of bottom end (became loose and flappy) 3) the mids and highs sounded sterile 4) motor boating I replaced the filter caps under the cover with Sprague Atoms using the same values (16uf, 475V) and 7 cathode caps? (25uf, 50V) caps and one bias cap (100uf, 100V). Now the bottom is very tight, almost mid-range like. The highs sound choked and slightly sterile. Any ideas?
