Levinson ML-11

I’ve recently acquired an ML-12 preamp, which needs an ML-11 as a mate to power it. One assumes, then, that the synergy between these two vintage pieces is quite good. Soooo...dual part question:

(1) Is anyone still running the ML-11 and ML-12 combo and what do you think?

(2) Does anyone have an ML-11 amp (with the rectangular power ports, not the round ones) that they would like to part with? I’m a bargain oriented guy but pay fair prices.

Focus is on Q1. Q2 is just there in case. I’m curious to hear what folks think of this combo. I would likely use it as a second or third system somewhere, and with speakers not needing a ton of current.

Thanks!
