Nope. He just judged what you mentioned about the issue and that you came from pedal building and now try to fix an amp with essential knowlegde missing and his advice has been correct (and was also a reason why I kept my mouth shut as I could smell the missing experience). People like him (and also me with ~30yrs in this trade) get a feeling on how competent people just by reading/hearing problem statement and if an advice will end as a success or disaster and with the comments you gave later in this tread regarding Ken's response I know that disqualified / blacklisted yourself to several people.
On a side note said I dunno believe that just changing the heater wiring as per MB did solve the issue, it is more likely that you had a bad solder joint or lead dress issue somewhere which has now been resolved unintentionally. I worked on 2203/2204 which had heater wires not even twisted and had been at an acceptable level of noise, even when being +40yrs old and having weak filter caps.
I think you are right because I started rolling preamp tubes again in v1 and there were a couple that brought some of the noise back to a level similar to it was after fixing the initial blown trimmer issue.
Yes I am inexperienced and I made this clear in the beginning. I don’t appreciate being mocked and characterized as some idiot who watches a single youtube video and thinks I know everything about amps. I have respect for people that have put years into this trade. I just wanted an opportunity to get my feet wet and I expressed I knew how to work safely so I don’t see why it is such a big deal.
If people want to disqualify me because I made a joke about Ken being grumpy, so be it. Im sure the man doesn’t appreciate being put on a pedestal as many around here seem to do anyway.
