  1. friend of mine has heard my DIY LaScalas, Belle and the big DBB Cornscalas. He's bugging me to build him a guitar amp. I've got enough stuff to build a decent 6BQ5/7189 P-P amp and was thinking to use a Crites cast frame 15". It won't have any tone controls or other effects, he'll do all that with his pedals.

    I was thinking to build a traditional open back box, direct radiator setup. Will the K-33 type driver go high enough to do a guitar? Or do I need some other driver completely? I've heard that you can't use quality stereo components in a guitar amp but nobody sez why? I mean, they'll play a guitar from a recording, right?

    I need to go look up the range of the k-33 type woofer and see how that compares with an electric guitar.

    Any bright ideas?

  2. the OP mentioned KDFR, that's Klipschorn, Decorator, Fir. The pics are not of Decorator models at all. Those are the regular B style, hardwood with the collar between top and bottom. I'd be figuring where the discrepancy is. Were those pics posted by the guy who owns the ones you're looking to buy?

  3. notice in this pic the RED wire coming off the NEGATIVE side of the silicon rectifier going to the little terminal strip and thence to the pair of resistors and on to the 4 caps and resistors. This is because the 4 section can cap was bad, couldn't get rid of the hum. I didn't know how to fix it so I sent it to a well-known Scott genius on this board who fixed it for me. I believe he used that pair of resistors to adjust the the negative 55V to the pre-amp tubes.

  4. Gil, if you see this, I was able to dig out that package you sent me back in Nov '04. Thanks again for taking time back then.

    I notice the plans on paper are SpeakerLab, are these still thought to be good? Or has maybe something better become available since them?

  5. Gil,

    Are you the guy who converted Khorn plans to use 3/4" plywood instead of the 1/2" Klipsch used?

    I'm back to thinking about building a set and selling my '60s. What concerns me is the pieces that have both beveled edges and are tapered lengthwise.

    I think you sent me, many years ago, a CD of plans and dimensions of building Khorns. Maybe I should dig it out.
