Thanks Chuck,
I need to get oriented with the schematics and the overall layout / functionality of the rig. It's quite a bit of components in there ...
It shouldn't be too difficult to trace the RF input signal. But unfortunately the bulb fuse is fine ;)
Which manual are you referring to ? I downloaded quite a few of them.
I removed the upper casing and the rig looks quite clean inside. It also has the optional CW filter it seems.
I couldn't get to the valves but they're all NEC.
