[AMPS] New to the Amps list (score: 1): Author: kkanakas@cisco.com (krishna); Date: Tue, 22 Jan 2002 11:23:00 -0500; Hi all, After having frequented the towertalk list, i am new to the amps reflector. Well, wanted that extra power after the tower has been installed. Now i do have some stupid questions on Amps. I am; /archives//html/Amps/2002-01/msg00167.html (8,189 bytes)
2. [AMPS] New to the Amps list (score: 1): Author: stevek@jmr.com (Steve Katz); Date: Tue, 22 Jan 2002 09:05:06 -0800; [Steve Katz] (WB2WIK/6): No, it's not. [Steve Katz] (WB2WIK/6): No, the AL811 does not have an unused tube socket. The AL811 and 811H do not use 572B's, they use 811A's. Only the AL-572 uses 572B's.; /archives//html/Amps/2002-01/msg00168.html (10,551 bytes)

4. [AMPS] New to the Amps list (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Tue, 22 Jan 2002 14:16:51 -0500; No. The AL811H is neutralized and has a few other changes. I'd go for the AL811H. You can drop in 572B's, but it would be a bear to add a fourth tube to the AL811. Three 811's are just on the edge o; /archives//html/Amps/2002-01/msg00172.html (8,341 bytes)
5. [AMPS] New to the Amps list (score: 1): Author: k4ik@subich.com (Joe Subich, K4IK); Date: Tue, 22 Jan 2002 15:07:22 -0500; Tom, Does the AL-811 have provision for raising the plate voltage by 800 to 900 volts to be more compatible with the 572B? As I recall an 811 generally operate at 1200 - 1400 volts where the 572B li; /archives//html/Amps/2002-01/msg00173.html (8,023 bytes)

7. [AMPS] New to the Amps list (score: 1): Author: 2@mail.vcnet.com (rich); Date: Tue, 22 Jan 2002 12:43:30 -0800; ? Good points, Joe. The 572B and the 811A have the same peak cathode emission, Mu, freq rating, and driving Z. The difference is in max allowed anode dissipation and anode supply V. cheers - R. L.

8. [AMPS] New to the Amps list (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Tue, 22 Jan 2002 21:44:49 -0500; No, but the gain is virtually identical because the driving impedance of the tubes is virtually identical. You do not lose any gain, since in grounded grid the ratio of driving impedance to load imp; /archives//html/Amps/2002-01/msg00176.html (7,822 bytes)
