Re: Bush VHF61 - magic eye not closing.
I've tried changing the EF89(x2) and the EABC80 valves - no improvement (purchased as NOS tested)
I'm not using the sets internal aerial as I have it out of it's cabinet. I don't have access to a proper external aerial at the moment, so I am use two pieces of enamelled wire, approximately 76cms each for the aerial.
I don't believe I am in a poor reception area, I'm in the city of Plymouth and the nearest transmitter is in Plympton (about 5 - 7 miles away)
I've taken some voltage readings from the EM81, as follows:
Pin 1 (grid) when tuned to a station
VHF = -0.5mv
MW = -2.2v
Pin 2 (cathode)
VHF and MW both at -0.2mv
Pin 7 when tuned to a station
VHF = 4.8v
MW = 75v
Pin 9
VHF 177v
MW 185v
