i think i have a plan on the brass,but i'm gonna wait till last on that...but by way of an update on this project
i had ordered a new 19t8 and 12at7 for this radio since they were the only tubes that didn't test near new. i was hoping that possibly the new 19t8 MIGHT do something with the slight buzz,since i'm about out of ideas and even theories at this point to solve it.... as well before i started messing with oscillator coil spacing that has existed for some 60 years,in order to fix the slight offset in the dial like the service info instructs,.i figured i'd get a new 12at7 and see if that affected anything there..both tubes work out to about a 20 dollar experiment,and i figured I'd at least know that all the tubes were then tip top even if it affected no change at all
other than these issues the set has been performing well enough,i find the heat from the 50l6 a bit worrisome but being that it seems to be operating on proper voltages,if not actually even a bit on the conservative side,i guess thats just the way it is...it gets warm enough on top that plastic would surely soften and warp,but i guess the bakelite can take it....??and i guess i know where to set a cup of coffee i need to keep warm
anyway i've had the thing playing off and on for a while now,and for a good while last night with good volume and sound quality,no issues whatsoever beyond those i've mentioned,so i shut it down for a while and when i came back later...dead,the dial lights up,but no sound...damn,a quick look inside revealed no lit heaters on the tubes...double damn,now of course in a perfect world the filament that went would have belonged to the 19t8 or 12at7 that i had on order,the ones that actually arrived just today...but nope,after checking across the heater pins of the four other tubes...I've lost a perfectly good testing 12ba6 to an open filament...dang setback #112 on this project,i got new tubes to put in,some stuff to try and i can't fire it up until i locate a working 12ba6 lol
