[19Seventy7]

I can’t seem to determine the two specific wires that are for the tuners valve heaters for some odd reason. I’m at a complete loss here as I can’t refer to the circuit diagram as the tuner section doesn’t appear on either one I have which is a shame.

The separate brown and white wires lead to the signals panel; The other three lead to the user control panel, so I’d think the brown and white should get shorted out, but this doesn’t result in anything.

On further testing on the signals panel there is a lack of continuity between the valves on the top and the valves on the bottom of the board so I think a component or two may have gone O/C. I’ll do some testing tomorrow when I have some more space. Some valve sockets also seem like they need “tightening” too, which I’ll do too and see if that helps.

If anyone has an idea on which pins need shorting out I would appreciate the help as I’m a little stuck otherwise.

Thanks
