Golden Tube Audio SE-40 - Good for SDA-SRS or 1Cs?

Hey guys, I have a quick question about the GTA SE-40:

1) Is the SE-40 a common ground amp suitable to use with SDAs? (I searched, but couldn't find an answer).

2) Will they be powerful enough to run my original SDA-SRS speakers? If not, how about 1Cs?

    I don't know if it is common ground. If it is, it might do ok with the 1C's, but barely. It will not work well with the SRS.

    "A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a t-u-r-d by the clean end."

  • Thanks, F1. I had a hunch it wouldn't be enough for the SRS's. I think I'll just pass on it, especially if it's questionable about being common ground...

    It's a pretty cool looking amp though, so I was tempted.

    Not to spread misinformation (me?!? ;) ) but weren't these GTA amps rather notorious for their fragility? Maybe I am thinking of a different model...

    It's a pp EL34 amplifier, isn't it? Something like 35 watts per channel, give or take (maybe 40 or even 50) -- kind of hard to imagine that would be optimal for any of the SDAs (although I have zero data on this myself!).

  • mhardy - I think it's a Class A 40 watt/ch amp, and yes, they were known for having a lot of breakdowns. It doesn't have EL34's in it.

    The guy selling the particular amp I was looking at says to have refreshed all the components, so it shouldn't have those reliability problems. I'm still debating picking it up to run with some smaller speakers. But, I do most of my listening on my SDA-SRS system, so (as F1 pointed out), it would be severely underpowered.

    I may be wrong, but I think that amplifier runs its tubes hard -- in other words, the fragility is intrinsic.
    What are the output tubes? 40 watts in Class A would take pretty massive high voltage and beefy output tubes.

    Still trying to find info on the design; here's a "review" of sorts from audio asylum.

    EDIT: well, ok, maybe mainly crummy parts (i.e., in the original, new production models):

    EDIT^2: aaaaaah. three paralleled 6L6 outputs :) 40 watts... hmmm...?

  • Sounds like you answered your own questions, mhardy. :+1:

    Agreed, it sounds like the parts were just sub-par and undersized. I'm still tempted, but might just look for something else with a better reputation...
