After a long, long sleep: ML-335

@bigkidz, @erik_squires...+1

I was a Levinson dealer and they use VERY high quality parts.  IMHO, you shouldn't have any problems, but use caution up front.

@terry9, @bigkidz...you guys are techs, right? I was always told that electrolytic caps age with ’"use", not with just "age". Is that true?

The ML-335 was made in 1998.  That makes it just 25 years old.  Maybe new in box or demo unit.  That's why I asked about age.

@musicfan2349...the ML335 will make those Acoustats "jump up and boogie!"

I run a completely updated pair of 2+2's and was an Acoustat dealer for many years.  GREAT speakers!!!

@gumbedamit...totally agree!  More panels are ALWAYS better!!!  That is indeed a fantastic amp.  

Your Spectra 33's are one of favorite Acoustats.  Only surpassed by the 66's.  

Nice system!  Roy does excellent work.

@musicfan2349...you sure have more will power than I.  I would have had that amp up and running minutes after I got home.  Patience I have not. 🤪

Probably for the best to send it in.

Let us know the outcome...
