Well I just found I got an absolute score on my second hand VLA. Got it off craigs list for $90 bucks, just opened it up an found that it has been retubed with N.O.S. RCA and GE tubes that probably cost more than the original unit new.
Sweet
I'm gonna keep the mullard and phillips N.O.S. tubes I ordered for flavor variations but I have to say I love this unit even more than I did when I got it initially
I work at a music store and I bought a VLA off of a customer who had re-tubed it with Mullards. I've had guys listen to it and swear I paid 5 or 10 times what I paid for it.
