1. [Amps] 3CPX800A7 Not Available (HAROLD B MANDEL) (score: 1): Author: "Tom Hix" <w4th@charter.net>; Date: Tue, 29 Nov 2005 13:11:57 -0600; Hello all; Can someone tell me what makes a 3CPX800A7 is so much better than a plain 3cx800a7 tube? The 3cx800a7 tubes were all the amateur amps had in the way of a 3cx800a7 type tube for many many y; /archives//html/Amps/2005-11/msg00516.html (7,993 bytes)
2. Re: [Amps] 3CPX800A7 Not Available (HAROLD B MANDEL) (score: 1): Author: jkearman@att.net (Jim Kearman); Date: Tue, 29 Nov 2005 20:14:26 +0000; The P version has the same external dimensions but taller ceramic structure internally, so it can withstand higher anode voltage. Eimac recommends 2250 max for the 3CX, and 3500 max for the 3CPX. For; /archives//html/Amps/2005-11/msg00517.html (7,781 bytes)

Re: [Amps] 3CPX800A7 Not Available (HAROLD B MANDEL) (score: 1): Author: HAROLD B MANDEL <ka1xo@juno.com>; Date: Tue, 29 Nov 2005 15:11:11 -0500; Dear Tom, The 3CPX800A7 has more ceramic material that separates the interior elements, allowing it to run at an elevated plate voltage. The 3CX800A7 is rated at 2200 volts on the plate while the 3CP; /archives//html/Amps/2005-11/msg00518.html (7,233 bytes)
