Replacement Tubes And Bias - YORKVILLE Traynor Custom Valve YCV4050 Mode D'emploi

Replacement Tubes and Bias

The YCV4050 comes equipped with 6L6 output tubes. Replacements can be any brand of 6L6 or 5881 and we
recommend that the bias voltage be measured and possibly adjusted (see below). Swapping in EL34/6CA7 output
tubes requires a change in one of the bias resistors to avoid tube overheating. The modification should be per-
formed by a qualified technician.
**The YCV4050 has test points and a bias adjustment pot. If you have installed new 6L6/5881s and wish
to check and possibly adjust bias, we recommend adjusting the zero signal bias to +75 mV +/-10mV DC at
each of the test points.
