I baught a pair of these amps a couple of months back and now need some help.
Although the amps came with the owners manual the biasing instructions were not included. I guess I have the earlier version of the amps as they come with 15 coupling caps and a test socket with 7 test points. The circuit diagrams available in the net are for versions with a larger no. of caps. If anyone has a copy of the biasing instructions could you pl send me a copy. Alternatively I am prepared to pay postage for a hard copy to Singapore.
Anpther issue is, valve 1 (6lf6) has a orange glow although there is signal to the speakers. Is the valve shot. Any coments on this would be appreciated. Currently I am not using the amp, need to resolve this first. If need be would replace with a matched valve.
All comments would be appreciated. Thanks
Nara
