Dual Volt Marstran 1202-118 Switch wiring?

Post by RockinRocket » Sat Dec 01, 2018 8:34 pm

Is it possible to switch the high low taps of the Marstran 118 of a on/off/on standby switch?

I'm trying to figure out how to wire the bias supply..

Is it as simple as taking the bias volts from one high volt tap and adjusting the feed with a resistor/trim pot?
Ive seen Gerorges dual tap transformer but he has separate wires for the bias feed.
Am I over thinking this? :?

The correct switch is here...http://valvestorm.com/Products/Switches Set up your bias circuit using one pair of secondaries. Then you will add a second resistor off of the switch that adjust the bias voltage when switching to the other pair of secondaries.
