7.6. Power Selector, alternative output tubes
Position „HIGH“:
KT150 / KT120
Position „LOW“: KT88, 6550, KT90, KT100 (EL34 with Restrictions)
The Power Selector allows adjusting the V 80 SE in accordance to the output tubes. Position HIGH
is reserved for the standard KT150 tubes as well as the KT120. In the HIGH Position the V 80 SE
is able to deliver up to 2 x 130 W RMS Output Power. The slightly weaker tubes type KT 88 or
6550 can be used in the position LOW. In this position the maximum output power is limited to 2 x
70 W to avoid overloading these tubes. The rather rare tubes of type KT 90 and KT 100 can be
used also in the LOW position.
The EL 34 can be used in the LOW Position in cases of speakers with impedance higher than 4
ohms.
Tubes of Type 6L6, KT 66, 5881, EL 519 and EL 156 are not suitable for the V 80 SE.
Before switching the Power Selector turn OFF the mains
After switching from power LOW to HIGH and vice versa the BIAS should also be corrected in case
of using the same output tubes. Normally there is only a slight correction necessary.
When using different tubes the BIAS has to adjust according to chapter 8.3
