Thread: Nad! 200-s

  1. #11
    When you said "200-S" I thought you meant one of these:



    I've owned mine since High School, and sadly don't use it much anymore because it's so damn loud! Our pal Steve helped me out by installing a three prong power cord so I would electrocute myself. Thanks, buddy!

    A buddy of mine, bass player and occasionally keyboard, told me a story about Sunn. I never verified this but the story goes like this...when Sunn was first starting out the guys took Bogen PA amps, put them in a badged Sunn cab or head and sold them as "Sunn" amps.

    I was suprised to hear this as I remember Sunn amps being high end and expensive. Only knew on guy who had a Sunn.

    As an aside...my bass player friend was trying to improve his bass sound. He constantly had balance problems that increasing power to improve bass would harshly distort the high end. He had a good high pay job at Mack Truck so money wasn't an issue. So as we talked I suggested he add an electronic crossover to the setup. This was 1972 so electronic crossovers were not common. Having a HiFi hobby I suggested he use a Crown VFX2 Crossover.
    Make a long story short he bought the Crown VFX2, Phase Linear 400 amp, 2 Cerwin Vega 18" speakers, Altec multi cell horn, Altec driver. We build two large bass cabs and he used a Kustom 100 guitar amp for the high frequencies, with reverb, and the Phase Linear and pair of 18 cabs for the lows. He would also scoop the mids...needless to say his bass sound was incredible!

    Sorry for veer...

    "Alternatively, you could just go the ultra-relic route with it. Basically go for a look that says the amp was on fire and they put it out using belt sanders."

    I believe the early Sunn equipment was based on (or actually) Dynaco pre-amps and power amps; back in the sixties you could buy a Dynaco which was built by Dyna or a "Dynakit" to do yourself, in either tube or solid state...the (Dyna) Stereo 120 power amp was a really big deal when it came out in the late 60's...not sure that was ever a kit. Organ pedal at the beginning of Wagner's Gotterdamerung, no problem!

    But I digress. It seems the topology on that amp is not much different than my '63 66-J, using only one half of a 12AX7 as a preamp, making for a very clean sounding amp. I cannot recognize it from the schematic, but probably Baxendall (sp?) tone controls, which are great but also rob a little gain...

    Good luck with that, bet its killer!

    I think Bill is correct. It was always my understanding that the early Sunn amps were built with Dynaco guts. Then Fender bought them out and destroyed them, like they have done with so many others...

    That's one sweet looking amp. Must be loud as hell.
    I'd love to plug my LPJ into that baby!
    Nice!

    If my memory is correct the 200S isn't as loud as you would think. I think the combination of the modest preamp gain, to keep it clean, and the the bias of the output tubes keep the volume in check. The 200S and its 4 EL34 tubes won't have the volume of a Marshall or modern amp with 4 EL34. It is a different breed of amp and another example of excellent high quality guitar amp. Guild amp have always high quality and well built amps. However their tone was not the popular amps of their day.

    According to Hans, they did have stereo output available on guitars as an option; but oddly only starting in '67, long after this amp was discontinued. A $25 option in '72. http://westerlyguildguitars.com/file...lists/72-2.pdf

    Great, looks like I'll need to hunt down one for my stable.

    All I can find at the moment is a Jetstar II Bass stereo.

    Possibly the main intent of the 200S configuration wasn't stereo but two equal power channels to have two guitars play through a single amp, or vocal and guitar.
    I remember as a kid few garage bands had a PA so vocals often came out of an amp.
