2 position rotary power switch

Looking for 2 position Rotary switch

Voltage 220v.

My transformer is rated at 6.5 amps

The pre-amp and buffer requires 3 amps.

Same switch (not the knob) employed in the amp below.

An externally hosted image should be here but it was not working when we last tested it.

A high power rotary switch with 6mm shaft is hard to find, I use a 0.25A rotary switch to control a line voltage high power relay.

9.5 Amps*220V=2090W. Are You sure the tubes handle that much ?
Look at 60s 70s vintage equipment
I remember disassembling baquellite ones from Preh and perhaps I have them lying around...

Pre-amp and buffer draws 3 amps at 12v.

That's 36W, which you divide by 220V to get the input current, which is then less than 0.2A.

You could use a fake rotary switch like the above (from Surplus Sales) - it is
actually a toggle switch controlled by a rotary action. Probably DIYable.

The "legendary" Tektronix 4xx scopes used a somewhat similar arrangement.

Maybe something like this would work?

I purchased a lot of these NOS switches for my recent EQ tube clone build. My total current draw is less than 1A and working like a charm.... If you're using 120V supply, these are rated at 6A.

Oops... sorry.. you said 220V, so 3A.
