Is this an assumption or did you check it before you did the work? Are you not willing to report what the redstripe bias volts are for fear of proving 46mA is just stoopid? I could check bias V's on one of mine but if you're not going to help yourself you might as well put this in the hands of someone that isn't hung up on the most basic part of a bias circuit or that can fix whatever you did.


20W of a 30W tube is 66%. On a data sheet that is ok. A boogie was not designed for that dissipation but this horse is long dead. One version of the 387/7581A story is the higher testing ones made the 35W cut. When you put a tube that was not a rugged 415 it slowly started to redplate so the 415 is the only reason you are not redplating from what you laid out.


How could this be more clear that you choose to ignore a problem biting you in the face?


46mA is not original to that amp despite your resolute inference that it was. To think it's ok because you tested it at that value after you did some work and then to resist normalizing it while asking for help is beyond what I should have stepped into. None of the pots you mentioned operate in isolation of the others either.


You haven't once bothered to run your blues in a safe zone. Good luck chasing your tail.
