I'm bumming again!! My Bassman is down again!! It is a handwired '59 Bassman with all high quality components, everything has been upgraded, Merc Transformers, frickin' Top of the line speakers and capacitors etc... I haven't played it in about 2 months, I have been moving. Fired it up to play a festival last week and it hums like crazy. was fine at the old house. took out tubes, changed tubes, still hums. How do I figure out if it is a transformer, filter caps etc... Thanks

Re: '59 Bassman Replica
Although I noticed a ground wire attached to my Master Volume Pot came off, could this have fried a tranny? Here is a pic of part of the guts.

how is that MV wired?Dax-The-Ax wrote:Although I noticed a ground wire attached to my Master Volume Pot came off, could this have fried a tranny? Here is a pic of part of the guts.
If you experience hum,it could be either a bad connection,a tube,or a bad ground system where you are powering it,or some other piece of equipment like stage lights radiating in the circuit.

Re: '59 Bassman Replica
If one wire has come adrift highly likely another has done the same somewhere, if it hums now and did not before you have to think a ground wire somewhere.

Hey Dax-The-Ax, what are the brand of polarized orange electrolytic caps as seen in your 59' Bassman Replica amp? Are they NOS caps?
