2. [AMPS] SB-220 failure (score: 1): Author: km1h@juno.com (km1h @ juno.com); Date: Mon, 01 Sep 1997 09:47:20 EDT; Mistake # 1 Pete! GRIN... What is the condition of components at the grid and filament pins? Did u install Rich's stuff there also? Check for open resistors or shorted caps. If it is original, check; /archives//html/Amps/1997-09/msg00006.html (10,867 bytes)
3. [AMPS] SB-220 failure (score: 1): Author: w8jitom@postoffice.worldnet.att.net (w8jitom@postoffice.worldnet.att.net); Date: Mon, 1 Sep 1997 15:02:40 +0000; Probably a gassy tube. Nearly all amplifier problems BLAMED on parasitics are simply gassy tubes. Replace the bad tube and repair the damage. Anything you do to the suppressor won't make a bit of di; /archives//html/Amps/1997-09/msg00013.html (8,223 bytes)

It allegedly disappears during the trip between the tube socket and the high-pot tester on the bench. The price of the suppressor retrofit kit is $14.50. So, doing things to th; /archives//html/Amps/1997-09/msg00017.html (8,382 bytes)
5. [AMPS] SB-220 failure (score: 1): Author: paulc@mediaone.net (Paul Christensen); Date: Mon, 1 Sep 1997 20:31:04 -0400; Rich: Let's face it. Selling suppressor kits at $14.50 in a very limited market-demand environment isn't going to make anyone wealthy.
