Anyone work/hobby on vacuum tube electronics, pre-solid state tvs/radios?

I feel like a lone reed (poetic but sort of accurate, and a quote from a movie!) in that, despite the trips to EPO in Sharpstown/Westchase, I don't have a hobby group to chat with.

Currently re-capping '57 RCA b/w tv, gathering materials for a '66 RCA color. Trying to troubleshoot a '55 RCA radio.
