Rob, The original feet for the AC-4, when used stand alone, had a 6-32 stud projecting from a rubber "bumper" that protected the table top. These were removed when the AC-4 was inserted in a MS-4 speaker cabinet. The feet were then used to secure the AC-4 to the MS-4 cabinet which had its own feet that were longer.
Below is one site where you can get these AC-4 feet. I have no interest in Donny's site other than as a satisfied customer. I have purchased the B and C line blue filters and white diffusers from him. http://www.wa9tgt.com/Drake_Cabinet_Feet_Bumpers.html As for crystals, everybody has their favorite source. I use JAN Crystals for the B and C lines I own/repair. I don't buy used crystals because you don't know what you are getting and most sellers want close to what JAN charges for a new one. Also, JAN provides a guarantee and will replace a defective xtal. How many sellers of used xtals will do that? 73, Ken, WA2LBI On 12/9/06, R. Ton <[EMAIL PROTECTED]> wrote:
