Default Re: Top caps ;can you explain them?

Get a moving coil (or another meter) and measure again. It should be 6.3v. 5.3 is a bit low. Looking at the Ace circuit, the valve heaters are in parallel. Check the earthing and the voltage adjust on the Mains Input.

Try taking the valves out and measuring the voltage. One may be taking too much perhaps?

Leave the LW slug for now, but clean the contacts on the Wavechange switch.

Cheers,

Steve P.
