Can anyone tell what model Melos this amp is?

We have some type of a Working Vintage Melos High Current Triode Amp that we have no info on. We dont know what model it is or anything. We have researched and cant find anything on it. Below are links to pictures of it, if anyone can tell me anything on this I would really appreciate it. Thanks
a maestro, i think
I can't answer your question, but fwiw, the former owners of Melos, George Bischoff and Mark Porzilli are now the brains behind The Memory Player, at The Nova web site is truly bizarre, but the Memory Player is truly an amazing product -- I've heard it and what they say is true. Mark Porzilli is also the designer of Scaena loudspeaker -- a genius imho. Anyway, you may be able to get more information via the Nova Physics Group.

Just an observation as a Melos owner: model numbers mean little with Melos. Most all Melos pieces were always works in progress. Great stuff, though not the most reliable and very hard to get repaired now because schematics are virtually impossible to find. Check all solder joints.
