Mark 2? I think...triamp.

Thanks!

I got information that it seems to be not an MK 2, it is an MK 1.

The Mk2 packs have much more chunky handles. Although I don't remember seeing those MF/HF knobs on the Mk1. They used to be holes with screw pots

I had a pair of Mki 100As, the owner had upgraded the tweeters to the SEAS variant but the bass units were non SL.

The picture is definitely of a mki amp pack and mine also had the knobs to adjust bass and treble.

I don’t think there is anything wrong with the mki amp pack once serviced, they will properly be over 25 years old, it would be sensible to do.
