Acoustat servo amps ??

thanks for the posts everyone.

plato et al: i have found a pair of monitor 4s w/ the servo amps ($1600) and was wondering if anyone was able to compare what these might sound like (i'll drive to hear them next week if it seems promising) compared to my model 3s with the transformers or model 3s potentially 'upgraded' with separate servo amps i might find.

thanks

hey plato thanks again for all the great info.

i'm not sure the vintage of my model IIIs. they were bought new by my father in '81 or '82 i believe but they may have been store demos and older than that however. receipts are long gone unfortunately (i hooked up with a guy at rockford corp who could have replaced the panels for free if i had it. crap.) how can i check to find out which version i have? -these aren't the medallion btw and have the 'internally wired by monster cable' sticker on the back if that provides a clue to their year.

that same guy at rockford can do the medallion upgrades ($700 including shipping) and upgrade the caps and wire if i supply him with the parts (i figure about $3-400 including cardas posts, etc. that option is what im debating against the servos. he recommended infinicaps and solens (47uf) but i've been told by an acoustat freak NOT to go with the infinicaps for this application because they sound thin. someone once told me they personally only use black gate in their acoustats but i cant seem to find any w/ sufficient voltage.

thanks again.

waveriding, thanks for the klipschorn idea. i'll probably do that. there is a company still making acoustat socks for virtually any model but they dont have a great selection of colors. For your records just in case you ever get a cat keep this handy: "The Upholstery Co" in mesa arizona 480-898-9521

guys thanks for all your help.

for the record and future searches on acoustat here are some good contacts:

for upgrades to the acoustat servo amps email mike at analogue associates: savuto@swbell.net. upgrades are all they do! i spoke to mike today and he seems like a great guy and i can tell this is a labor of love for him. he's an accountant by day.

for repairs on stock servos try 'sounds like new' at 561-736-0041

I'm thoe echthited!
