It's 39 years old and started sounding "tired" so I had a cap job done and "blackfaced". That didn't really improve the sound any so I changed all the tubes (tried new tubes and NOS tubes)...not much difference in sound. Changed the speaker (tried a Cannabis Rex and Weber 12F150 25W)...a little better but still sounds muffled and mid-range and honky. The bass doesn't seem to do much and the treble is very dominant so I removed one side of the bright cap which tamed it some but even now the treble at 4 is still dominating which causes the amp to sound thin and brittle and honky...did I mention honky? I'm debating replacing ALL the caps on the turret board with new Sozo caps since I want to check them all out anyways. It wouldn't take too long to just replace as lifting one side to measure them. The amp has the "blue turds" which I understand don't usually go bad so should I change them or not? I wonder if the iron could be breaking down and needing replacing. How could I easily confirm if the transformers (PO and OT, choke) are bad? If I'm going to replace all the caps on the board, which caps do you recommend? I was considering standard sozo or the new sozo blue molded caps. Anyone have any experience with these? The half-dozen resistors I checked are all within spec so I don't think I need to worry about those...or do I? Any help/advice would be greatly appreciated.
