1. [AMPS] SB-220 Conversion Confusion (score: 1): Author: apight@pa.net (a.p.); Date: Mon, 15 May 2000 10:51:29 -0400; Amp aficionados, et al; I have a 6 M SB-220 conversion that works quite well with one tube. Input SWR is 1.1:1 and output plate tune is at about 1/3 mesh. Efficiency is as expected. However, when I p; /archives//html/Amps/2000-05/msg00151.html (7,578 bytes)
2. [AMPS] SB-220 Conversion Confusion (score: 1): Author: 2@vc.net (measures); Date: Mon, 15 May 2000 09:20:31 -0700; Two tubes requires that L be cut in half and C-tune be doubled to maintain the same Q. Guessing at tank values is not good engineering practice. And remember, Pi-networks are not quite resonant on t; /archives//html/Amps/2000-05/msg00153.html (7,616 bytes)

You did not state the measured value of L with two tubes. Stating the number of turns does not get it. It is the inductance that counts. -; /archives//html/Amps/2000-05/msg00157.html (9,113 bytes)
