1. [Amps] Sb-200 plate current (again) (score: 1): Author: stewgoat at indy.net (Jeff Stewart); Date: Sat Jun 14 08:46:54 2003; I just did a visual and a 33 ohm resister off the grid of one tube R21 or R22 is cracked in two. The tube on that side has a discoloration on one side (the gitter appears to be at the bottom) so it m; /archives//html/Amps/2003-06/msg00090.html (6,866 bytes)
2. [Amps] Sb-200 plate current (again) (score: 1): Author: gmguerin at voyager.net (George & Marijke Guerin); Date: Sun Jun 15 09:21:08 2003; Hi Jeff, etc., I lost one of those resistors many years ago. I would say old age. Maybe some stray current, but I replaced the 33 ohm 1W with 33 ohm 2 Watt resistors. One of my tubes was not working; /archives//html/Amps/2003-06/msg00099.html (8,682 bytes)
3. [Amps] Sb-200 plate current (again) (score: 1): Author: wb8jkr at juno.com (wb8jkr@juno.com); Date: Mon Jun 16 08:16:03 2003; Max PLATE current for a 572-B is 275 ma. per tube, maximum grid current is 50 ma. per tube. In a properly operating SB-200 you'll see 500 ma plate current keydown, about 85-100 ma grid current and 20; /archives//html/Amps/2003-06/msg00101.html (10,058 bytes)
4. [Amps] Sb-200 plate current (again) (score: 1): Author: 2 at vc.net (2); Date: Mon Jun 16 08:16:19 2003; ? the typical grid-current in a 572B will not blow even a 1/4W 33-ohm resistor. Rich, AG6K, 805-386-3734, www.vcnet.com/measures; /archives//html/Amps/2003-06/msg00106.html (9,322 bytes)
