ok i give up...the thing has a buzz,will always have a buzz,and probably always did...i don't know what else to try short of replacing every single component and rewiring the whole chassis...and I'd lay odds it would STILL buzz!
can anyone add ideas to this list...
caps are done...all except the couple hundred ceramic discs[seems that many looking anyway
]
tubes are good or new
tube shields are in place and well grounded to chassis
AC plug orientation makes no difference
cap lead dress or positioning makes no difference
grounds are tight solid and good..there are only a few chassis grounds in his thing...components that were originally routed to them are still...
the speaker and associated bracket has been replaced...the ground through there is also 100% solid
the volume control ground is solid...and has not been disturbed at any rate
i finally got around to finishing the install of the new speaker and bracket today,i also redid one of the caps to ground after looking at some "before pics" last week,i noticed i had it all of a inch or so down the rail from where it was originally[yes I'm down to THAT level of desperation!i'll try shit that i know will make no difference!]....i powered it up and the buzz seemed quite nearly gone,the new speaker sounded good!i put the case back on and the buzz is now not only back but louder than ever.....wtf?!??
i have no doubt that this is just a stupid problem,an iffy connection somewhere or at worst one or a few of the multitude of ceramic discs may have failed...or something...but i just give up,the only way i think i'm gonna get any satisfaction out of this thing is to find a very large hammer and smash it to bits...
