Default Re: Restorers dream part 2 the chassis.

If the U25 is glowing a nice purple colour it is a sign that the line output stage is operating and producing AC EHT. The U25 is either faulty [gassy] or the EHT smoothing capacitor, the brown Visconol .001uf is faulty. It can be disconnected if this has not already been done and will have little if any effect on the raster. Good progress. J.
