I just got a LK-500ZA in for repair, the bypass cap
at the plate choke had failed and it took out the
grid shunt. According to the paperwork I have on this
amp the values of the shunts are simply "factory selected"
does anyone know what the value is? If not, I guess
I'll have to do it the hard way.
What a crap design, no method used to prevent
the B- from rising above chassis ground in case of a B+
short.
