1. RE: [Amps] TL-922A - Loud Pop, Blown Fuses (score: 1): Author: "Mike Clarson" <mclarson@rcc.com>; Date: Mon, 6 Dec 2004 12:19:06 -0500; Don't know if the TL-922A has similar problems, but my SB-220 has exhibited evidence of parasitic oscillations, and, when that happens, one gets the ".22 Caliber" pop. It is unpredictable, and, it ca; /archives//html/Amps/2004-12/msg00113.html (9,700 bytes)
2. RE: RE : [Amps] .82 ohm (score: 1): Author: "Mike Clarson" <mclarson@rcc.com>; Date: Tue, 7 Dec 2004 12:28:35 -0500; It seems quite unlikely that 120 watts would blow the .82 ohm shunt. Oter forces were at work (Parasitics likely). I often looked at the grid current but never actually used the reading for anything.; /archives//html/Amps/2004-12/msg00123.html (9,741 bytes)

Intended for continuous heavy duty use. Used HYVOL (the oil?) that allows compact size with high capacity. Looks like an oil filled unit,; /archives//html/Amps/2004-12/msg00219.html (7,985 bytes)
