An electronic cathode bias switch is used to replace the bias switching relay next to the fan. /// note -- the reason that a SPST vacuum relay is required to switch the output is that no DPDT vacuum relay is fast enough. Is there some TL-922 / QSK owner over there who can explain me how to integrate this kit in an unmodified amp ? Make a bracket to hold the 2 RF relays, mount the relays with Silicone rubber adhesive as per <http://www.somis.org/relay-mtg.html>, allow to cure a day or two, remove the original 2 relays, connect the Fig 7 <http://www.somis.org/HSS-diagram.jpg> circuit and the new relays to the points indicated. A schematic would be great too. Thanks a lot. Richard L.
