SB220

[Alex Wa4Ak]

I have an SB220 in near mint condition.  My problem is that when testing
according to the manual, the high voltage readings are a bit low, perhaps 400
volts low.  I think it may be the silicon diode stack in the high voltage power
supply, but the manual and schematic only refers to them as silicon diodes with
a Heath in-house part number of 57-27.  Does anyone know a good modern
substitute for these and a source for them?  Any assistance would be appreciated.
