I'm talking about a 3 way switch with standby on the bottom, off in the middle & on is up.
to go from standby to on you have to move through off. I was told that it was off so briefly that it did not matter.
Seems like off, standby, on is a better way.
Please edumacate me on whether this matters or not.
Thanks

I have a Supro that has "Off" in the middle position, and it hasn't been a problem for the past 40 or so years. You have to keep in mind that Stand By is simply turning the B+ "high voltage" to the power tubes off, while letting the heater voltage to the filaments continue. Personally, I think the best way is the more popular Marshall/Fender way:
2 seperate switches. But, hey, that costs more $$ to make!
i have two switches on my valveking. i think it works great.
know any reason why the same switch couldn't be wired off/standb
know any reason why the same switch couldn't be wired off/standby/on? or no?
It's a cost and convienience thing on the part of the designer. Centre-off toggle switches are exactly that - off in the centre, where the centre pins are not connected to either of the outer sets of pins. So one pole of the switch is wired with both outers to the mains and the centre to the transformer. The other pole switches the HT, but the HT is connected to only one outer. You get standby toggled one way and normal operation the other.
To ask for a custom made toggle switch is expensive.
