Apr 6, 2018 · Usually I use EL84 in all my amps. Because of that I asked about EL84. From many months I tried to find good schematic to my purpose and to this time I don't find ready to …

Jul 12, 2019 · From the tube charts: At 360 Plate volts a pair of 6V6s in PP needs -22.5 fixed bias volts, or +22.5 cathode bias volts. @ 250 Plate volts, an SE EL84 needs 7.5V bias. You can …

Jan 19, 2014 · I had built a SE EL84 and switched out to a 6V6 after not liking the distorted sound. It did sound much better with the 6V6. But I may have had other variables with mine all I had …

Sep 15, 2017 · Hoffman Amplifiers Tube Amp Forum, EL84 SE BIAS. I have the el84's biased hot in my Orange amp with a 120 ohm resistor.

Feb 23, 2016 · Hello all, Building a weird little single ended special, with two EL84's in a parallel SE configuration, and wondering the what-if's about pushing the plate voltage(s) to about 350 …

Jul 30, 2019 · Re: Second design - SE EL84, cascode pre « Reply #83 on: August 27, 2019, 04:06:45 pm » I "test" my PSU at the 1st tap virtually every time, I've got a bunch of 2K N 5K …

Jul 15, 2012 · I built a SE using a paralleled 12AT7 (changed from ax7 for less distortion) into 5879 pentode feeding a 6v6. With a little lower voltage, an EL84 should sound really good as …

Sep 29, 2010 · Re: my se el84 running at 370 vdc ? « Reply #19 on: September 21, 2010, 06:45:48 pm » As you lower the current,the plate voltage will rise.That's normal with less load …

May 21, 2014 · A Champ is a "4w amp" so you might say SE 6V6 gives 4w (from a 12w tube), so we might say SE Class A yields about 1/3 plate dissipation as output power. That means SE …

Jan 13, 2018 · The EL84 stage is basically the same except for the grid resistors which I followed from J.Mesa. Now its time to ask some questions. I hope some here can help guide me …
