Good afternoon All
I have recently acquired a 4cx250B linear from Frontier Electronics LA-2
2metre Linear Amp.
It hasn't had any volts on it for years.
I have a large mains variac that I use to run up my homebrew stuff but how
should I use it to run up this old linear...should I disconnect all the
supplies to the valve first ?
what sort of mains supply voltage should I start at and how long should I
take before I get it up to our 240vac mains input ?
Tnx in anticipation
Iain G4DPF
