Hallicrafters S-40B
Has any one come across the hallicrafters S-40B with different wiring in the secondary HT and LT wiring, my receiver only has one 6.3 volt secondary the original circuit has two, one 6.3 volt windings is for the heaters and dial lamps, the other for HT circuit.
This set came like above from the USA. 73s Andy 2E0NDZ |
