    Pay? No need for that. So did you fire up the 260 yet?

    Thanks, guys.

    Have yet to fire the 260 but maybe in the next day or two.

    Edit - just fired it up with a dbt without incident. Am excited but know I've got some old components to replace before this 260 sees regular use.

    Judging by the pictures and his description all that's been replaced are a few resistors.all those with coupling caps would have to go along with the electrolytic capacitors and the big round filter cap to enjoy years of worry free listening.there really isn't much parts in these amps and if you can solder you could probably do it yourself with very little effort.

    Yeah about 2 pairs year LOL. Overall these amps are very rare compared to other brands. At any rate I have way too much gear anyway...

    Sam,
    Do you know the 411h ? Is it more 750ish than 412ish ? The one that has been listed on the bay sure looks like a 412. just curious... I probably won't be buying it.

    I know the 411H from two examples that have appeared on eBay, and one AKer that owns (or owned) one. Apparently they had some issues with it and it was discontinued in favor of the 412. As far as I can tell, only a few hundred were built, as I don't recall seeing one with a S/N higher than 400. I do know that at least one of them was exchanged under warranty for a 412-4.

    The 411H uses a big Ashland motor similar to (or maybe identical to) the motor used in the Rek-O-Kut B12H. It seems to be a hybrid idler/belt drive with a three-pulley mechanism that changes between 33, 45, and 78, but I've never had one in hand to verify that. The bearing, at least the outer platter casting, the trim wing and the selector knob were all shared with various 412 models.
