[AMPS] 30L1 Grid circuit (score: 1): Author: w8jitom@postoffice.worldnet.att.net (w8jitom@postoffice.worldnet.att.net); Date: Wed, 14 May 1997 15:24:20 +0000; Hey Guys, Look at the grid circuit of the Collins carefully, and look at a few things. The theory presented (Orr also presents the same theory in his "Super Cathode Driven" circuit article) is that t; /archives//html/Amps/1997-05/msg00105.html (11,789 bytes)

The reason does not really matter, the fact the caps are there is the only important thing. So while y; /archives//html/Amps/1997-05/msg00112.html (11,645 bytes)
4. [AMPS] 30L1 Grid circuit (score: 1): Author: pgerba@crl.com (Peter Gerba); Date: Wed, 14 May 1997 19:50:32 -0700 (PDT); I have a 30L1 question... maybe Tom or Carl can help. I have a Round Emblem model. I was told that the RF cable used to connect the Xmiter (KWM2 etc) to the input of the 30L1 was of critical length.; /archives//html/Amps/1997-05/msg00113.html (8,522 bytes)
