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.
