Re: PYE 15A valve question
Hi Ronners,
I have never seen a 15A, but wonder if the valve holders (sockets) are the thin brown paxilon type?
The paxilon type are very brittle and it is easy to 'make' another key way if you do not understand the need to line the key on the valve spigot with the recess in the holder... the valve spigot key always wins!
As you say an EBL31 is hard to find and someone might have tried a substitute, but that would need changes to the circuit. Have a look under the chassis and see if there are any obvious changes.
But the common thing about octal valves is nearly all have their heaters on pins 2 and 7. So just making another key way by 'design' to fit a substitute is not going to work.
You have a PM. Alan
