The SBT-1K uses 872 rectifiers. I've found some 4B32 solid state units which have a note on them that they are replacements for the 872. Should i or should i not use them? I don't know how much the voltage would increase but it would be Ep only. I don't think it would hurt the 8295 which runs 3100V on it now with the 872's. Comments. Larry W0OGH
