I am in need of some amp revival advice. I have a 1st generation Gonset
GSB201 that I want to restart. I have not put power to it since 2008 when
I replaced the power supply caps. It worked fine at that time. Since
then the amp & myself have moved cross country with the amp stored for years
in a semi-conditioned (no humidity control) environment. The tubes are the
older model Svetlana 811As (with anode heat sinks) last replaced about
2002ish and have low hours. I also have the set of well used RCAs that I
pulled in 2002. I have the amp at home now in a full conditioned
environment and thought I would let it set there for a week or so to dry out
in the event something inside soaked up some of that humidity.
Should I bring it up on the old RCAs since I understand it's hard to get
good replacement tubes?
Should I/can I use a Variac to bring it up slowly without having to do
disconnect anything inside the amp?
If I get it up to HV, how long do I need to heat the anodes to activate the
gettering process? The amp has no internal shutoff bias so it normally
flows anode current at idle.
Anything else I should be aware of?
Many thanks for advice!
