1. [Amps] NCL 2000? (score: 1): Author: "Paul B. Peters, VE7AVV" <ve7avv@shaw.ca>; Date: Sun, 28 Sep 2003 10:04:03 -0700; I'm looking for comments (pro and con) regarding the NCL 2000 amp. I have an opportunity to buy one dirt cheap and aside from the cost of the 8122 tube, I'm wondering if there is anything else I shou; /archives//html/Amps/2003-09/msg00200.html (6,669 bytes)
