Finding a good tech is getting harder and harder... There are fewer and fewer of us around. Most of the younger techs don't have any "real" experience in analogue recorders, nor have they cut their teeth in major studios... so mainly they plod along as best they can. The guy who fixes your guitar amps might not be the best person to fix your Ampex. Try and find out which tech the largest studio in your area uses, and get that person over to take a look at your Ampex machine. Try and find someone who's working on these older tape recorders all the time, not just once in a blue moon.
