I upgraded the Bassman VT-100 2x15 speaker cab with 2 JBL E140-8 speakers. It's much louder now.
But now the Bassman 100T amp has a weird fizz on the decay of the notes on the clean vintage channel?
It doesn't seem to do it on the OD or overdrive channel, so I don't think it's an issue with the speakers. I'm pretty sure I heard it with the old speakers. I replaced the V1 tube that is unique to the vintage channel, and I thought it went away, but it's back now.
I've been studying the schematic and using google to try and get wise.
I will do a little testing from outside first.
1. Try another bass amp on the speaker cab.
2. Try another speaker cab on the Bassman 100T.
That will prove it is in the speaker cab, or the amp itself.
The fact that it isn't in th eoverdrive channel pretty much says it's in the vintage channel preamp section, not the power amp, or the speakers. But I will do the tests anyway.
I have read on google, it's a common issue with bad caps, bad solder, bad tubes,....
Nice that they narrowed it down for me?
