Sunn 200S...

Do a TB search. You will get more information than you need.

Also, take the time to look around in the TB gear reviews.

 

I got mine for $220 used, but that was a VERY good deal.


Basically, with an efficient cabinet, they're very loud, very clean (mine doesnt distort until 9 on the volume, and it's very slight), durable as hell, simple (only volume, treble & bass), yet complex (that two band EQ can get a wide range of tones, just gotta learn how to use it).

Going rates on them used go anywhere from $200-400. They're great workhorse amps, and I currently use mine actually as a practice PA head. Works like a champ.

 

200S
1966 Similar 60 watt head to the 100S, but for bass with Volume, Treble and Bass controls, plus Hi-Boost and Low-Boost switches. Two D140s were placed in separate folded horn sections of the 42"x24"x15" bottom (same size as 100S).

1969 Change to 6550s

Also, the 60 watt rating is VERY conservative, and with a solid state rectumfrier, bumps the wattage to around 90-100 watts.

 

Back 1970, I tried out( and won the gig on a temp bassis) for a three peice power trio type band. I was not used always using great gear and was basically a plowboy from out in the country.
They owned all Sunn gear, PA, guitar and bass amp. We practised using one side of the PA, 100S and a 200S. This was a real thrill for me. A couple of weeks of intense practice and our first scheduled gig (for me any way). I was told to show up a half hour before the gig at a local High School and that all the gear would be set up. About peed my pants when I walked in and saw a bouble bottem 200S for me! HECK I would have driven the 40 miles each way and played for free just for the chance to play through that rig. Guitar had a double bottem 100S. We had two more similar sized gigs, then I was informed about the "important big gig' at the armory.
I show up and here is the 2000S one cab in the guitar stack, one in the bass stack, and on top is the 200S side ways. Each side had a 2000S and 1000S cab along with the appropriate 'practice amp' on top. The PA was double cabbed and horned, you remember those huge JBL's with the huge Lens. A wet show was the main light show.
It didn't take a geniose ( or a good speller)to recognize the guy watching me most the night was my replacement. It was actually the bassist I replaced, they kicked him out to straighten up his attitude and just wanted somebody to make him want back in.

Lessons learned;
1. subbing can be fun. I started doing a lot of subbing from 1 night to 3 months.
2. I kinda giggle when some asks "What is a good practice amp?"
3. I developed a love for 200S cabinets. Did you know that the Ampeg BT140 is within a fraction of an inch in all dimensions/ The 200S and SBT are amazingly similar also.
4. Later in life I used a V4B witha 200S loaded with K140's and I will say that- that particular 100watts will play a reasonably sized bar. I used to snicker at lesser companies power claims.

Best Of Luck,

PS the B15S cab is pretty close to 1/2 of a 200S. The Ampeg served me well for may years. I think a major part of the sound was the cab.
