Q & A / Sunn 200s running on 6L6 tubes?!
« Last post by Pacafeliz on April 07, 2024, 08:16:31 am »Hey folks, nice to be back after many years of absence!
I'm back here in Mexico and happened to pick up an old 200s, and it's working. But i did realize it has a pair of 6L6 tubes instead of KT88s - that can't be right, right? The rectifier is a 5U4.
Original owner says he's been running it like that for the last 20-30 years!
The outputs on the back are not marked what impedance they take, so i guess it's 8 and 4, right?
So my brother has a big Fender Dual Showman cab here, which should be 4 ohms, so I connected that one.
No nasty noises, good sound, but one of the power tubes was massively redplating, so i shut it off.
Will take it back to Germany with me and get some KT88 first, then have my tech guy check it out.
Any thoughts?
Cheers,
Pat.

Q & A / Re: sunn 250watt stagemyster
« Last post by Isaac on March 10, 2024, 10:40:54 am »Lurk,The only thing I found was an old ad on Reverb that said it takes "a standard 1/4" footswitch." Pictures of the back would seem to corroborate that. If so, that opens up your options.
Did you ever work out a solution to the footswtich issue? I find myself having the same lack of information. I also got nothing else from the guys over at Sunn currently as all the documentation for the Stagemaster seems to have been purged ages ago. They do have schematic info for the Beta Lead and Beta Bass, which Ive heard some folks whisper that it is similar to the Stagemaster, but could go either way. Ive also heard the Enforcer footswitch also works.
IF an Enforcer footswitch would work, you might try this: https://www.dpeffects.com/2021/02/sunn-enforcer-footswitch.html

Q & A / Re: No sound out of Sonic II/200s ext speaker port
« Last post by Isaac on February 16, 2024, 10:09:54 am »The JBL K140 has a top end of about 2000Hz. That's an octave or two too low for what most people want for a guitar sound. It will be a dark and midrangey sound, not bright. Imagine playing guitar through an amp with the treble turned all the way down. So, strictly for guitar use, I'd say that the Sunn Transducers will yield a better guitar sound. 130s - D, K or E - are a different matter. They are loud, clean, and low distortion. Not everyone's cup of tea for guitar, but some love them. I played with a guy who used a Sunn 1200S into two cabinets with two D130s each. What a sound! Loud and clean, and the differences between guitars and pedals were very clear.
