Members emazur Posted September 4, 2014 Members Share Posted September 4, 2014 Hi. I have an AB Professional model 2220 amplifier driving a pair of Altec 1003B horns. It seems to be very close to the Model 200, but I was wondering if anyone had the service manual for it. ThanksElias Link to comment Share on other sites More sharing options...
Members soulx Posted September 4, 2014 Members Share Posted September 4, 2014 A little better than a year ago I had some specific questions about changing some of the component values in one of their crossover cards. I emailed their service department. The company is more-or-less gone, but there is still a guy keeping up the service end of things, and he was really helpful about finding me some really old and rather obscure schematics. I was pretty impressed. Link to comment Share on other sites More sharing options...
Members agedhorse Posted September 5, 2014 Members Share Posted September 5, 2014 I'm about as familiar with the old AB product line as anybody due to my involvement with the company over a period of 10 years, ending about 15 years ago. I don't recall that model number, nor do I see it in any of my factory paperwork either. It's possible that it was a special run of 200's for a private label type customer that used them originally in pre-packaged theatre installations (all the big manufacturers did some form of this back then, including Crest, QSC, JBL, Carver, etc.) I have a 200 currently for sale on eBay by the way. Don't have much in the way of service docs. as I mostly serviced them from memory. Link to comment Share on other sites More sharing options...
