    Unhappy My Bad...

    Got it. I'll stop posting these amps to Audio Heritage. I ended up on this particular thread as it was one of the only ones where people were specifically interested in Soundscrafstmen (there are lots of places to broadcast to the world, but I was trying to find enthusiasts). Didn't mean to violate policy. Out...

    Nothing wrong with posting items for sale. For your benefit and ours they should just be in the Marketplace section where we'll look for them and you'll get more response.

    I'd love to have two, but then I'd love to have money, too!

    S800's

    I bought the 2 with the missing face plates. These are like new old stock. THe scratches are fresh like they had put them in a rack new and covered them up in storage and scratched them pulling them out. Not even the slightest dust residue on the PCB's. Whoever pulled them out scratched them up. Great sounding (tested them on my 4412A's) and a lot of watts for the buck. Nice mosfet shoebox amps.
    XPL 200's, XPL 160's, XPL 140's, L7's, L5's, Homemade L Center, 4412's, L60T's, L3's, L20T's and still looking.

    Bolt Covers?

Must be a common rectangular button from that era since SAE used the same ones. EQ slider knobs seem to get lost, too. And the Pro-Control and Pre-Receiver knobs are quite unique and often missing. None of my ten-or-so components are so afflicted, luckily. Adult-owned by people who cared enough to keep the original boxes seems to help. And I keep a dusting brush on hand. Easy enough. While we're on the topic: For the later EQs, the plastic tips on the sliders are matched pretty well by the smallest bolt covers in the Lowe's hardware bins. You can even get them in red to set-off the main gain controls from the third-octave controls which is why I found them. Then one dead CX-series pre-EQ can supply practically an entire forum membership with spare parts . . .

    Any errors on the description please tell.

    Now,

    The story with these amplifiers is that during their production years according for those in the know in hi fi they weren't good for hi end and according to the DJs they weren't good for professional use, go figure.

    I have tube amps, class D amps and I'm thinking of building one of Nelson Pass class A designs.

    If one reads all over the web it seems that the general idea is that there's no perfect amplifier and neither are these.

    But I have to say they sound extremely good.

    After several A-B tests the newer MTX Soundcraftsmen seem to sound a little cleaner than the older models. It must be taken into account that the capacitors in the old amps are over 20 years old and that component technology has improved vastly. Also the use of the newer Profusion and Magnatec mosfets might make a difference in some of the newer models. This amplifiers are a huge bargain. I have bought several ones in horrible condition and since the sound comes from the "circuit" I just put them on a wood plank or buy a new chassis.

    I have invited some naysayers to do a blind test with some of their amps but they refuse.

    If anyone is interested in schematics email me and I'll gladly cooperate with you.

    BTW,

    I have over 30 Soundcraftsmen amps and I love them all.

    Anyone have the schematics on the MTX S800? I really would like to a copy before they become extinct since I have 4 functional S800's. I called MTX and the guy said it was proprietary, give me a break.
    XPL 200's, XPL 160's, XPL 140's, L7's, L5's, Homemade L Center, 4412's, L60T's, L3's, L20T's and still looking.

    I'm always in the market for the big pcr-regulated FET amps. I have 9 of the bigger soundcraftsmen amps now, each like twice the more common 'shoebox'. I have 5 of the 900X2 with the soundcraftsmen name, and 8 with the earlier PM 1800 name, but the same inside as far as I can tell.

    I mention it because I'd love to have one more.

    Soundcraftsman Amps

    Just my 2 cents.

    Back in the late 70's, early 80's, I bought a brand-new amp at the factory in Santa Ana, Ca, (I don't remember what model, but it had a graphic EQ and 200 WPC @ 8 ohms.

    I was underwhelmed, to say the least, it sounded bad & distorted with my old Bose 901 II's, (insert groan here).

    I traded it for a Paragon 12A Tube pre. The guy thought I was crazy, but I've never regretted my decision, and still own and use it every day. Did I get a lemon?
    Repeat after me, tubes and vinyl.

    AFAIK, Soundcraftsmen never made an "amp" with a graphic EQ. They were famous for their pre-amps with built-in EQ and, in later years, they even had power-amps with LED signal-strength arrays, but unless you had two separate units I don't know how you got that combination in a Soundcraftsmen unit.


    You used the words "bad", "distorted", and "Bose" in the same sentence!

    Your right, I did. And that is one reason I have a pair of L65's and a pair of ESS speakers

    My memory might be fuzzy, (it has been a LONG time) but I swear it had a EQ built in. And, I know it was an amp, because I used it with a preamp.

    So If I am wrong about the EQ, show me a list of amps that I can refresh my memory on. And, Soundcraftmen did have a factory in Santa Ana, right?

    They were in Santa Ana until MTX acquired them and sent them to Hell.
