Westone Thunder 1A preamp queries

[BreadBin]

Oh great hive mind, I seek answers to questions...

I have a friend with an old 1A pictured below - it has a broken switch. Is this an active/passive switch? Does anyone know if a suitable replacement?  He would like to run passive if possible, so the simplest solution is to replace the switch if that is in fact what it is. 

Alternatively, is there a decent replacement preamp available? Does @KiOgon provide something suitable?

Thanks in advance 👍

@BreadBin Yes I can do a passive kit, have done some in the past for Westones, PM me if you are interested.

I also made a neater version of the wiring schematic for my own reference (plus I didn't have much work on at the time...)

@BreadBin, if your mate's active circuit is still working, I'd be interested in buying it off him. Mine is fecked.

Can't help feeling your volume is not going to be working well if you followed that circuit to the letter.

Wow, thanks everyone some great info there 👍

He has decided to keep it original (sorry @Rich!) so I am looking for a suitable replacement switch.

Do you have such a thing @KiOgon?

@BreadBin, give me a minute to check my spares box, I might have a flat bladed switch of that type.
