That’s interesting, I’ll have a look.
Thanks sjs.
For some reason HH I don’t get the option to send you a message. Can you send one to me & I’ll email you the schematics?
Them pesky mods have probably banned me again and didn’t tell me this time. 
Message sent mate.
Thanks
Des.
Up date - A few dry solder joints, a new 5687 valve, and 2 grid stopper resistors on 2 of the tubes and bingo, silent !
Job done, thanks for all your help, especially Guy for the schematics.
