Bands Using SUNN / Sunn Rigs 2024
« Last post by Janisdooms on May 05, 2024, 03:51:24 pm »Send your Sunn rigs! Here's mine 
. Some non Sunn stuff too, 1979 Beta Lead 212 combo, 1984 Enforcer 212 combo, Crate Powerblock, and Carvin RL410T (for bass).

Q & A / Re: Sunn 200s running on 6L6 tubes?!
« Last post by Soundmasterg on April 19, 2024, 12:05:31 am »Black electrical tape is a no-no with high voltage DC. They modified something in there with the extra electrolytic caps too, as Loudthud noted. Personally if it was my amp, I would go back to stock with the whole circuit arrangement, but change all the electrolytic caps in the amp, and for the first two filter stages, use series connected caps with parallel resistors as I noted to get a good voltage rating that is sufficient for today's wall voltages. Even if you are running it at 110 VAC, the stock 525V caps were right on the ragged edge of OK. In the 200S I used to have, I used series connected caps to get to a 700V rating on the first two stages so it would be safe even with turn on surge.

What it does is to change the low end cutoff from 80Hz to 40Hz. That extra octave is below anything a guitar typically produces or a guitar speaker reproduces.
I'd have to review the schematic to see how the HI BOOST functions.

Well i and the amp made it back to Germany safely. Got some KT88s and plugged it into my 110v step down converter.
There is sound, but a loud hum over it, that wasn't there before.
Opening it up it all looks original and pretty solid...
( Pictures not duplicated )
...but this here has broken, might have happened on the rough plane ride.
EDIT: resoldered it and now it's workig nice and quiet again!
Only the Lo and Hi switches don't change a thing?
My amp guy is currently on vacation, dammit.
So looking at the pics, is this an 8 - 4 Ohm output?
BTW yes all the pots are dated 1967.
Any other thing that jumps in your eye?
Thnx,
Pat.
It looks like your amp has been modified to have the 4 Ohm tap hooked to both output jacks with no switching involved. You can use either jack for a 4 Ohm speaker cabinet or use two 8 Ohm cabinets.
Other mods seem to have been done. There are two large resistors connected to the power tubes, not sure what the story is there. The three axial caps clustered around the original main chassis mount cap aren't stock. One of them says 150V so not sure what's going on with that. Then there is the black electrical tape, another mystery.

« Last post by Pacafeliz on April 16, 2024, 07:38:09 am »Ok so i sprayed the pot and switches with Deoxit, now the latter ones work intermittently - they'll have to go, eventually.
But for now I'm a happy cat!
Thanks for your help!
