AVO 2 panel valve tester MR2 and missing cutout
Having located a valve base panel I now have a complete AVO 2 panel valve tester (plus spare control panel) so have started the restoration.
However I am puzzled by the reference to a second metal rectifier, MR2, and a "cut out assembly" on David Williams' redraw of the circuit. These do not appear on the original AVO manual nor the Chris Colebrook redraw. Neither of my panels have MR2 fitted. Does anyone know if this was something fitted in later versions? Peter |

It was fitted to the admiralty pattern 55046 version, and is quite handy if the cut out sensitivity is working as it should still.
