Hughes & Kettner schematic needed

[Stratfordade]

Does anyone please have a schematic for a Hughes & Kettner ATS MkII?

I’ve found one for the ATS 120 which is a close relative but has many differences (e.g. the MkII has two pairs of J49/K134 MOSFETS on PA board but 120 just has one pair, Mk II has more fuses on PA board).

Usually easy to find H&K documentation but this one is elusive!

Thanks in advance.

ATS-60?
ATS Mk2 ... which model?

It's only an amplifier ... what is wrong with it?

The only model reference is that ATS MkII on the front panel Jon. Nothing at all on rear or on any of the boards inside (at least not on topside - haven’t pulled any boards yet). It’s more similar to a 120 than a 60 as has pair of ECC83s in overdrive channel. Unlike the 60 and 120 it has a set of five slider pots for the ‘tube’ channel but uses rotary eq pots for clean channel.
