Good evening all,
A friend has given me a beast of a thermonic valve, a half-wave rectifier, RG4-3000, to turn into some sort of table lamp.
Access appears to be somewhat tricky as i'd need to remove the glass envelope. I remember removing the envelope of a smaller glass tube pentode when I was 15-16 years of age to produce a scaled technical drawing, but for the life of me I can't remember whether or not I broke the glass asm I never bothered to replace it..
My question is, has anybody attempted anything similar and how did they remove the glass envelope in tact so that it could be attached at a later time?
Legh
regards to all and thanks for reading
