there is a high speed ,low noise rectifier upgrade
4 new caps, 6 bypass electrolytics, and im thinking about the wbt binding posts. its about $750 plus shipping and with the new posts would be $1100. that includes the $125 per amp bench fee. the person i spoke to at cary said they would be like a new pair of amps, open and bigger stage with more focused imaging.
but being without a little music when i get home from work even for just a few minutes a night for an entire month really would suck. so im holding out until i find something to test out while they are gone.
turns out even though they dont make my amps for production anymore they still build custom pairs and keep upgrading them. and since i bought them used and(for the first time in years) see them sticking around for awhile , i figure they can look them over and make sure they are in perfect working order.
