[QUOTE="Ivan Beaver, post: 74893, member: 30"] Re: More old stuff from Grampa's attic One band I worked for in the early 80's had one of those. If the console sat for more than a few days-you had to get a pair of vice grips and "break" the pots loose. They would turn fine for a couple of days after that. I have a 6200 in my collection in my office. I don't know about that particular console-but on some Tapcos-if one leg of the volume pot developed a cracked connection-the op amp would go into open loop gain-and INSTANT uncontrollable feedback. The volume control was in the feedback loop of the op amp. It didn't happen very often-but when it did-WOW! [/QUOTE]
