21. [Amps] 2 x 8877 amp (score: 1): Author: wlfuqu00@uky.edu (Bill Fuqua); Date: Wed, 06 Nov 2002 16:40:20 -0500; I once ran 4 6AG7s grounded grid in parallel with 1200volts on the plate and 300 watts PEP plate input. But being a non-drinker this was a dry amplifier. I had made a heat sink out of a block of alum; /archives//html/Amps/2002-11/msg00072.html (11,752 bytes)
22.

26. [Amps] RMS-PEP & 2x8877 (score: 1): Author: wlfuqu00@uky.edu (Bill Fuqua); Date: Thu, 07 Nov 2002 14:46:00 -0500; To understand what Average power for one cycle means you must first realize that "RMS Power" is meaningless. What most are calling RMS power is Average power. See my previous example. 73 Bill wa4lav; /archives//html/Amps/2002-11/msg00107.html (14,381 bytes)
