I have a pair of the late Paul Gryzbyk's TAD-1000 monoblocks, which have been dark for a couple of years. I want to power them up. I have bought a kit to place between the power tubes and the sockets, with leads to permit bias reading/setting on a multimeter. My amp pair was from the later-run, with LED lights to guide in setting the bias , but I don't know what bias values should be as measured by a meter, and since the amps were supplied with EL34s, I don't know if the built-in set-up will correctly guide me to correctly bias the KT88s currently installed, or what a proper bias would be on kt77s (which I might like to try)
Can anyone help? I found the instructions for his smaller amps on the web, I have a copy of the instructions for using the built-in light system, but I can't find the instructions for the earlier version that used a multimeter.
(I can't do a search here, because I haven't had the requisite posting history.)
Thanks for any help you can provide!
