Mark, wouldn't be me if I wasn't scanning the main text & utterly missing the "small print"! Oh well, I do plan to become more active on this forum also since we have plenty of time currently!
Jeffrey, that is a very good point & one I'd not thought of. Mainly because I'm not super-experienced with how valve radios function & I was merely going from another FET circuit kindly devised by someone on the other forum which did include the "filament" resistors. To be honest though, I may carry on and use the pair of resistors just to keep the loading on the filament winding similar to if it had a valve in place because it might help stabilise the voltage and avoid the other valves being over-run (we have fairly strong line voltage here, mid-high 240's usually)
That aside though, just ignore the G1 part of the circuit & include a 75 or 150mA fuse?
Thanks again, Dan.
