Re: HV rectifier tubes, capacitors, other stuffFS
Hey folks,
I did not offer any toobs for sale, 860s or 866s. I posted to correct Bill
Noble's misprint.
His correction appears below, and the original posting is below that. I wont
fix blame--
Reinhard. :-))) Oh, what a tangled thread we wove.
Happy day,
Ralph Zekelman

Also note that all Mercury rectifier tubes like 866A's and 872A's are not
particularly great in high E RF fields. I personally like the MMD
(multi-mini-diode, to steal from others), but tubes can recover from
overstress conditions, where as solid state semiconductors are less
forgiving...
