Mike, you may be right, but I'll try again as Trevor suggested. It just seemed odd to me that the o/p stage was working albeit intermittently until Tinned/soldered the pins of the o/p valve, since then not a peep, even if I gently rock the valve in it's socket. I have a new 5-pin valve socket on order, so when it arrives, I'll change it, which should cure the proble. The output valve or any known equivalent(s) seem to be almost 'unobtanium', so I hope it's not faulty.
