[Amps] GS35B questions

[Marius Hauki]

OK, thanks. Will consider a interlock between the racks as well as a
separate ground strip between the racks. Will probably have to isolate
the Bminus and therefore the casing of the HV connector (if circular
connector used), since I will run grounded grid and need a measurement
resistor for grid current to chassis ground from Bminus.
