42-380 Restoration Started
#4

Thanks for the schematic heads up. Got it, and now digging in.
Plugged the chassis into the variable isolation transformer and slowly brought the voltage up to 115.
Sure enough there is the 60 hz ripple on the 195V line, and the base of the 6X5G is cracked as well.
I have ordered a new tube, a 6X5G(T) which should be a direct replacement for $4.00; instead of $16.00 for a used 6X5G. So far I have changed out the capacitors in the bakelite line filter condenser pack with new X/Y safety caps hidden inside. I used a heat gun to melt out the tar that originally filled the innards of the pack, unsoldered the old caps and soldered in the new ones. I'll be replacing the electrolytics and recapping the rest of the unit when the tube and caps arrive. I have also played with cleaning the chassis with Naval Jelly to dissolve some of the surface oxidation. It seems to be working well. I did have to rinse it after with electronic cleaner degreaser because I was concerned that if any got on, or in a tube socket it would cause corrosion.
Question to the knowing: Has anyone used the 6X5GT to replace a 6X5G and is it OK to do so?
Thanks again
