TBS Tracking Bias Supply Kit     $46 Printer-friendly PDF

Down the road, you might like to convert a cathode-biased amp fitted with a PSK-2 to fixed-bias. The TBS allows you to retain the PSK-2 and convert it to a PSK-1, which fully accommodates fixed-bias operation. Combine the TBS with the appropriate BMK Bias Mod Kit to attain the required number of bias pots and meter jacks for either the push and pull circuit halves or for individual output tubes.
