Good results re the 3456 fix.
Bloody yaesu ft101 driving me insane, got the receiver mostly working, got final tubes in, replaced one anode cap, eventually got them working - who puts the heater circuit through an accessory socket-plug (that mine didn't have! ), 'neutralised' the finals, now not getting getting' drive' into them.
Time for the problem to 'mature' a little - before my 'grumpy old man' attitude takes over and I hurl the bastard at the wall! (And get a hernia for good measure)
