Chuck, I'm glad you are ok and you never gor seriously hurt or killed. Just look at it this way, you got a 2.5kV zap from one of the coolest prewar sets.
I'd love to own a TRK-5 or a TT-5, but I pretty much have a better chance at winning the lottery then even getting an oppertunity of owning one, or even getting the money to pay for it.
I think this is an important thread. I handle the 10BP4 I have with great care. An implosion would pretty much be leathal. This is quite un-nerving to me, but if I'm careful, I'll be ok. The HV cage is open as well, but I want to sand it and paint it with some metallic black gloss paint. Once it's done the HV cage goes on. The 60Hz HV windings are more dangerous, but a prewar HV supply or a postwar HV supply can both be lethal. I am more concerned about CRT implosion than HV, but I've worked with HV more than I've worked with CRTs.
With the 21" color CRTs. I'm getting one and I'm glad I read this thread. I will be extra careful when I handle the CRT, as if it implodes not only a good 21" round color CRT not exist anymore, I wouldn't either. Thanks so much for your posts and these safety tips.
