It is in the 3-500Z amp section. I took a different approach and redesigned the cap for a lower minimum C in the small section. Sold them for several years. Look at the photos of the Commander 2500; you will see that they use that design and buy them from OEP. I also have a number of brand new Cardwell dual caps built for Alpha. They are 8-55 and 15-220pf at .075" spacing. A modified 154-10 and just perfect for a pair of 3CX800A7's, etc. Price is $50 shipped. Also have a a number of used National NCL-2000 dual section caps; 8-85 and 12-165pf at .0625" spacing. They hold up fine at 2500VDC and are $30 shipped. 73 Carl KM1H _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.
