Hi Paul, to clarify,

1) was it a power amp only before and is it an integrated with volume control and input selector now?

2) if so are you using the relay board or the original type rotary selector?

3) at what stage did the hum start, after the conversion, or was it fine for a while then started out of the blue etc?

4) is it on both channels, on all inputs, have you replaced or moved valves across channels, any other investigations so far?
