Dallas Arbiter Soundcity Studio 20 / Elpico mains selector plug 1960’s

So as someone who sells parts for vintage amps(as well as vintage amps and speakers) I think I have outdone myself in the rarity department

Here we have a mains selector plug as used by soundcity/Elpico on their 20w amps

Niche I know, perfect if your amp is missing it’s selector

I don’t expect this to sell quickly but as the saying goes find another…

Anything else just ask
