'79 Sylvania E48 console superset

[radiotvnut]

I just found a Sylvania 25" superset from '79 that uses the E48 chassis with the dark tinted delta gun CRT and single knob varactor tuner. The cabinet is decent and the TV still works; but, the CRT is getting tired. While watching it, I heard a loud HV arc along with the picture blanking out for a split second. I suspect the cause is either a dirty anode connector, an arcing CRT socket, or an arcing CRT. Maybe it will do it while I'm looking in the back of the set and then I can see what's going on. Concerning the tired CRT, I have a 25V Zenith chromacolor CRT that I could stick in there; but, the Zenith tube won't have the dark glass. Anyway, I'll try to get some pictures of the set tomorrow. I supose I should keep the old dark glass Sylvania tube in the event I can one day find an outfit to rebuild it.
