Hi decca4(A),
I think the problem is with this particular tube (6lf6). When I interchanged it with tube 3 it still glowed in its new position while tube 3 was OK.
Yes according to the circuit diagram all the 6lf6 tubes need to be matched. I am in the process of getting a few tubes in the hope of finding one that matches. Following this and once I get a copy of the biasing instructions I would bias the amp.
Thanks,
Nara Naidu
