I have installed the PT, lamp, on-off portion of the isolated volume knob and run the heater wires, 5v and the two 3255VAC HTs, grounded the CT and installed the chord. The chord is also grounded to the chassis. The volume pot/Power switch is not grounded. I've also got a .5 amp slow blow fuse on hand for testing. I'd like to power up and get voltages from my transformer primaries and secondaries, filaments and B+ voltages before installing the board and inputs. Trying to do this in phases. Does anyone see any problems here? With a smaller fuse, i dont see any danger to the components. The OT is not connected and no tubes installed (could I install tubes?). With no filter caps the B+ should be low, but I'd like to see where it is before I stalling it to the circuit. Anyway, anyone see a problem with this approach?
