My "keeper" SE 45 amp

108.200.38.54

After sitting on the shelf for 15 years or so, I recently put a pair of DS-050s to use. Although the endbells are now powder coated, they are brass. These were also were built with M4 lams. The chassis is CNC machined billet aluminum with powder coat. Circuit is based on the Bugle. Thanks Mikey and Gordon!

Jam,

Looks killer, were did you get the chassis made?

Take it those are 6SL7, sylvania's right? I always liked the brown base versions of those!

Thanks,
Gordon

  Thanks, Gordon! Had two of these chassis made locally 15 years ago(barter deal). 12SL7(stocked up when NOS were bargains).

Hello,
Very nice build. Please provide some photos of the insides if you can. A schematic or a description of the ps and circuit changes would be nice. Enjoy your new amp.
Regards,
David

  More photos of "keeper".
  
  The circuit is basically Bugle, but with 12SL7 drivers. Also power supply is rectified with Hexfreds, but I added a damper diode tube for slow warm-up.

    Hi jamsburg
    
    Good build and thanks for the photos. layout is neat. I'm also contemplating a Bugle build to power my Altecs, and have downloaded and am studying the schematics carefully. I am planning a pair of monoblocks, rather than a stereo one. Would you mind sharing the vendor from whom you sourced the caps and resistors? I see the Hammond 157G chokes, specified in the circuit.
    
    Thanks
