321. [AMPS] Parasitic suppressors/another question, (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Fri, 9 Apr 99 14:19:25 -0500; The "typical" anode resonance of a 4-1000A is around 80 MHz. However, with my current design that uses NO suppressor resistors in the anode, I cannot find a resonant dip on my GDO in that region or; /archives//html/Amps/1999-04/msg00191.html (13,513 bytes)

What I do have though are series RC networks from cathode pins to ground. Perhaps the 4-1K wants to see some capacitance to; /archives//html/Amps/1999-04/msg00232.html (7,549 bytes)

Then you can say with certainty that the suppressor resistors were OK before the oscillation. So perhaps the oscillation did cause the damage. But then you have t; /archives//html/Amps/1999-04/msg00247.html (9,504 bytes)

If I put in 100 Watts, 20 times that is 2 KW. That is great! In fact, it's damn near what I see in my 4-1K amp.
