It is very different (AC-coupled and normal bias only) and will need to be fully refurbished.

Congrats

Congrats! WTF though, a normal bias only SRM-1/mk2?

^ Yep, they had both normal bias and pro-bias SRM-1/Mk2. Considering how often they come up for sale, I don't know how many normal bias SRM-1/Mk2 they sold.

Ahh. I have only seen the 1 normal, 1 pro and the PP versions.

They came out in same year, but the price difference was minimal between the two amps so I suspect most folks opted for pro bias version which had both pro and normal bias jacks.

The normal bias only version was made well into the 80's going all the different boards I've seen used in them. Most are pretty easy to fit with pro bias...
