wiring a voltage selector

hello
i m wiring a Marshall voltage selector for my 1202-118 (marstran)

http://www.mojotone.com/amp-parts/Switc ... tor-Switch" onclick="window.open(this.href);return false;

The voltage selector switch has 220v 230v and 110v for the usa.

i m in Europe and need the 220v and 230 v,

should i use the 100v or 120volt tape from the transformer for the usa voltage -
the voltage selector switch has only 110volt

what are you doing with the 2 left tapes -
the switch has lugs for 6 different tapes- bot only printing for 3 tapes (220v 230v and 110v)

it would be possible to wire all 5 different voltage tapes but there is only the printing for 3.

do you wire the 2 left tapes or just tube shrink those.

i also wonder the price difference

I can only help with your first question...

I read here recently that the 100V tap is for Japan, the 120V tap is for the US.

Hopefully someone familiar with the switches will be along (wake up :wink: ) soon to answer the rest of your questions.

I thought in the USA its 110volt.
So I will use the 120 volt tap (USA)
thank you

I suggest that you twist the whole primary loom together to the selector.

Use the 120v tap for US, 220v for Europe and 240v for UK and solder those to the selector. The wires you do not use keep the wires the same length as the others but fold them back and put shrink wrap on them, then hide the ends in the bundle by the selector, then you have choice if you need them later :wink:
