Default Re: Yet Another Bush TV22

It doesn't appear to be a valve fault because half a dozen different ECL80s all display the same frame ripple and the cathodes are at ground potential. I did push the heater wires about this morning and did achieve a quieter sound intrinsic but have yet to see any frame improvement.
