I had a pair of Monitor III's for 20 yrs. Sold them cheap because it had to be local buyer. There were a couple upgrades to that amp, which in itself was an upgrade to the Acoustat-X amp. They involved mostly cap changes, but significantly tightened up the bass. Joe Curcio had an upgrade to the amp years ago but it cost a couple grand, which was out of my league. Acoustat gave up on the servo-charge amps because there wasn't a market for those large tube-driven monster speakers. You might see if www.musicalconcepts.com would consider looking at the transformers. There might be some other folks with former connections at Acoustat that are still out there....

hey anybody know where i can get my acoustats upgraded? i'm looking for the medallion upgrade and i'd like to get the caps upgraded. i think the panels are ok for now. i have model IIIs - Los Angeles area would be ideal but anywhere that does a good job is ok. rockford isn't doing work on these anymore, by the way.
