Apr 3, 2023 · The output tubes can be configured in either pentode mode (normal) or triode mode for a slightly darker tone. Three drive tones in triode mode were also added. All of these tone models are demo'ed in ToneNet without cabinets, so you should also try them with a cabinet that sounds good to you. Let me know if you have any questions.

May 13, 2021 · I am looking to compile a list of tubes with different triode gain factors because I would like to experiment a bit and really tweak some of my amps preamp stages. Not sure how popular this concept was in vacuum tube production but I do know a few of these oddballs exist like the 12DW7 and also...

May 22, 2017 · I don't have experience with any Jubilee combo, but I have owned a 2553 half stack which is essentially the 2554 in a head format. When changing between the 50 and 25 watt settings the tone is really different. 25 watt (triode) is much warmer, rounder, and a little more spongy. More bluesy, vintage-y maybe.

Apr 9, 2013 · The circuit is simple. Signal comes off the plate on the first triode and goes through terminal 1 and on its way thru a .02 coupling cap and 470K resistor on its way to the grounded volume pot. There's a .047uF cap going to ground off the wiper and terminal 3 has no connection.

Dec 11, 2017 · The tubes have well balanced triode pairs and a very even flat response. Compared to a Tung Sol it sounds a bit flat, but so does a NOS Mullard. Microphonics is not an issue despite the larger that average plate structure. The transconductance on my sample was the same as two NOS samples I measured.

Sep 25, 2019 · In triode mode, there is more sag because the plate voltage has more of an effect on plate current in a triode. The supply sag created by the power transformer resistance lowers not only the plate voltage, but the screen voltage as well, since the screen is nearly always a filtered version of the supply going to the plate.

Sep 26, 2011 · Have been all over the map from the new Vox custom heads to Bad Cat Cub IIIr, 3rd Power Dual Citizen and the Maz 8, which is most appealing to me right now because it's the lowest-powered of the bunch (while still having some of the versatility of pentode/triode plus reverb) and the studio combo is a nice form factor for me.

Nov 18, 2023 · Heavy +1. I updated my Floor to 3.7 and took it into the rehearsal room this weekend for a jam, expecting to test out all the new models—but literally didn't make it past the 2203.

Jul 10, 2017 · Hey! There's a nice Rambler near me that I wanna pick up, but it's a bit older (a 2003). I was wondering if anyone knows if there have been any changes to the amp from then, aside from the speakers? There are Kingpin 60's in there, could I order the newer Carr/Eminence speakers for it? Thanks y'all!
