Just to answer the question I posed. When I disconnected the heater supply the heaters went out but the sound through the headphones stayed the same in every respect so it looks as if the predictions about the valves doing nothing were correct. Thanks for the "neatness" comment.

Hi Ken.
A bit of a con then regarding the valves. That is very disappointing indeed.
I've been asked to build a headphone amp with 6080 valves

Allegedly these are excellent for the purpose, ready built versions can cost up to £600
