Default Re: New build WDPhono 3 Questions; heater voltage/LED

It must be an update.
I take it you don't have the rotary switch on the LHS of the front panel to switch in the LF filters? They are a decoration anyway in my opinion, mine stays on the 10hz setting permanently.
No matter it wont affect the heaters.
Have you considered the possibility of a duff valve?
Also try checking the voltages with just 1 valve in and swap it round the sockets, if theres a wiring fault it might show up?
It'll be something fundamental it usually is.
