Default It is done!

Hey guys,

After A LOT of work on my speaker amp project, I have finally finished it (at least for the moment). Since this was my first speaker amp project, I decided not to skimp out on parts and chose the Nichicon Muse lines for all electrolytic caps with all film caps by Solen and Holco / PRP resistors.

To break it down, this is a CKK-III PreAmp with a simplified Epsilon12 muting circuit set to a 3 second delay, 2x LM3886 based GainClones running off snubberized, regulated LM338-based power supplies at +/- 31V. There is also a very nice AlienDAC wired into the source 4x selector with an RCA loop out.

Power supply caps in the GainClone PSU are 3x 3300uF Nichicon Muse FX, all others are Nichicon Muse KZ.

There is also a tiny and simple RFI power mains filter, as described here, only it's single stage and without the choke (top left of photo).

All equipment is tied together to a star-ground before it goes through a ground loop breaker to the case.

Insides:


Input Wiring - input wires are 99.99% silver


AlienDAC - 1000uF BlackGate power supply cap, 1.0uF AuriCap outputs


CKK-III PreAmp with


GainClone (a little messy) - output wires are 18AWG Cardas


GainClne PSU


The casework - Case from www.vt4c.com/shop, Vampire RCA, and a Neutrik switching headphone jack.



Finally sitting on my desk with the speakers and my Millet MAX, hooked up with an Iron Lung Jellyfish power cord and my new 18AWG Cardas in Teflon RCA.


Oh, and yeah, it sounds great driving my newly acquired Wharfedale 9.2 - thanks Bryan - HiGHFLYiN9!
