So I have an amp build that I just finished. For all intents and purposes it is an Allen modded bassman with 100w Iron (UL OT with the UL taps disconnected) and B+ in the 450v range with 2 5v4's or 470ish with SS rec. 2 6L6's and an 8ohm out. The filtering is stock for an AB763 circuit. It was built from a bassman 135 that I got for dirt cheap. And yes it is heavy as hell.
I am liking the sound so far. It cuts really well and has ridiculously quick response. The tone is big, raw, and open with not a ton of compression so it is very unforgiving when you play. The problem is that the notes seem to decay pretty quickly. I know this is a function of the huge OT, the filtering and the huge power supply.
So what can I do to help with this issue? Switch to a 50w OT? Keep a 100w OT but change it out for a non UL type?
I was thinking about dropping the b+ but where I am at is right in super reverb territory. Same with the filtering. My biggest thought is the OT at the moment.
Any insight would be much appreciated!
