Default Re: Restorers dream part 2 the chassis.

Sounds good. The LOP is definitely running and trying to make EHT. Whether blue or purple, the glow in the U25 is not healthy. There should just be a dull red glow from the heater.

Don't remember a visconol or other EHT smoother on my T311. Can't see on on the circuit either. The CRT has a graphite inside and out to make an EHT smoothing cap. I don't know if metrosils can go s/c. The one on my T311 had gone before I owned the set and it really isn't needed.
