Hi everyone, I've just bought a 1974 Bassman 50, which sounds ok, but is lacking volume. While this may not be the issue, I of course need to replace the electrolytic caps. Trouble is, the values in the amp don't seem to relate to any of the possible schematics (AA371, AA270, Bassman 50). Here they are: 2x 70mfd 350V 3x 20mfd 500V 1x 16mfd 475V 1x 1mfd 50V 1x 5mfd 50V 3x 25mfd 25V 2x 80mfd 75V They all seem to be original (photo's available) as they are Mallorys and look old! So, should just replace the caps with as similar as possible, or work off a schematic? Thanks for your help!
