Mercury Rectifiers and the Frozen Northeast!

It got down to -3 last pm, and hasn't been above freezing in 2 weeks. Adds yet another twist in using mercury rectifiers.

My music room is a large space which gets pretty cold. I've been using a programmable delay of 2 minutes between filament and B+ on a pair of 866jr's. The last few days' I've been getting flashover unless I increase the delay to 4 minutes. Darn things sure don't like starting up at 50 degrees.

I guess that's why the 3B28 was marketed as an "all temperature" replacement for the 866A!
