I have an Eastern Electric Minimax preamp modded by Tom Tutay for sale. It is easily in 8/10 condition. I'll have to check the tubes it has in it. I'm a little reluctant to let it go. You just never know when you might want to throw some tube warmth into the chain. Plus it's just a cool little piece of gear with tons of tube rolling options.
Feel free to ask questions. PM me. Let's talk.

Update : Looking for around $
700 $675. Stock units normally sell (used) on Audiogon for around $600, so I believe my price is about right especially considering it is an upgraded unit.
