External Speaker Jack/s
20
These under-the-chassis mounted 1/4 inch jacks allow convenient connection of an
8-ohm external speaker cabinet. If you disconnect the internal 12 inch Celestion®
speaker (2x10 inch on YCV40T), you can connect up to two 8-ohm external cabinets.
Replacement Tube Selection & Bias
These YCV amplifiers come from the factory equipped with matched 6L6 output tubes
(YCV50B uses matched EL34 output tubes). The circuitry has been designed to
accommodate any type of EL34/6CA7 as well as any type of 6L6/5881 output tubes (as
long as the four, or two, output tubes are of a matching type). The amplifier has also been
equipped with bias sensing points for each of the output tubes as well as a recessed bias
adjustment trim pot. This makes tube replacement quick and easy.
**We recommend adjusting the zero signal bias to +75 mV +/-10mV DC at each of the test points.
Please refer servicing to qualified personnel.
