[Boatanchors] Diode replacements for 866 tubes, ratings needed ?

[Gary Schafer]

And how would you define high voltage spikes? How do you figure that a choke
will not give you any spikes that the diodes see?
Do you not consider start up time important?

While I am being rather conservative with diode ratings spikes can not be
ignored.
