The PV-12 was never that good of a preamp. I don't think its worth putting that kind of money into. You would probably be better off selling it and put the money toward one of their better models.
your experience with mod or upgrade companies.....
i called c/j and talked with jeff, found out that cj now does upgrades for some of their equipment. my pv12 would be about 900.00 four just 5 caps. that seems a little high for just that amount of work. what other compy that you know of is doing this, i know a while back i heard about different ones, but you dont hear to much now. there was a group of indian guys i talked with a while back that seem to do a lot more for at lot less, but i forgot the name of them.. please give me your input, as always is appreciated.......
