SRS 1.2TL Project

This was a little more demanding than a typical SDA re-build. I had a budget to work with, so Sonicaps an Mills Resistors were used for the Hi-Pass, and Dayton 5% for the Lo-Pass.
Dayton doesn't make a 13.5uf cap, so two 6.8uf caps in parallel were used instead. All resistors were relocated to the bottom of the circuit board to clear space for the new caps. The Sub-Bass Drive Inductor was replaced with a #16 gauge Erse SuperQ. The large (and heavy) 16mh spool inductor was eliminated, and a new mounting board fabricated from 1/2" MDF. A #1/4-20 Hurricane nut was installed and glued to the MDF, and holes were marked, drilled and countersunk for the new nylon stand-offs. The new Erse Inductor was installed at an angle to keep it as far away from the small Inductors as possible. Small strips of Armacell foam tape were installed on the back side of the MDF, so that when it was bolted to the back of the Aluminum front plate, it would not spin or vibrate.
To complete the work, a new #10 gauge Interconnect cable with SpeakONs was fabricated, the Binding Post Cups were modified with a SpeakON Sockets, new Gold Plated Copper Insulating Binding Posts, and finally, new #10 gauge jumpers were fabricated, with Gold Plated Copper Fork connectors. Turned out to be a lot of fun.

Very nice work Dave. Always much easier when the budget is bigger, but when it's not a higher degree of creativity is necessary."Science is suppose to explain observations not dismiss them as impossible" - Norm on AA; 2.3TL's w/sonicaps/mills/jantzen inductors, Gimpod's boards, Lg Solen SDA inductors, RD-0198's, MW's dynamatted, Armaflex speaker gaskets, H-nuts, brass spikes, Cardas CCGR BP's, upgraded IC Cable, Black Hole Damping Sheet strips, interior of cabinets sealed with Loctite Power Grab, AI-1 interface with 1000VA A-L transformer

Very nice looking work, and I bet they'll sound great!Family Room, Innuos Statement streamer (Roon Core) with Morrow Audio USB cable to McIntosh MC 2700 pre with DC2 Digital Audio Module; AQ Sky XLRs to CAT 600.2 dualmono amp, Morrow Elite Speaker Cables to NOLA Baby Grand Reference Gold 3 speakers. Power source for all components: Silver Circle Audio Pure Power One with dedicated 20 amp circuit to main panel.
Exercise Room, Innuos Streamer via Cat 6 cable connection to PS Audio PerfectWave MkII DAC w/Bridge II, AQ King Cobra RCAs to Perreaux PMF3150 amp (fully restored and upgraded by Jeffrey Jackson, Precision Audio Labs), Supra Rondo 4x2.5 Speaker Cables to SDA 1Cs (Vr3 Mods Xovers and other mods.), Dreadnaught with Supra Rondo 4x2.5 interconnect cables by Vr3 Mods. Power for each component from dedicated 20 amp circuit to main panel, except Innuos Statement powered from Silver Circle Audio Pure Power One. -
Very nice looking indeed. No fair, no fair. I could never create that

westmassguy Nice job, The only thing I would be concerned about is the connectors for those #16 gauge Erse SuperQ inductors. If it was me I would make sure they were insulated some how.

I would use at least some electrical tape or even hot glue to keep any shorts from happening, but than again I have a tendency to be a bit anal about short circuits.“The two most important days in your life are the day you are born and the day you find out why.” ~ Mark Twain

I loathe hot glue, it should only be used for Martha Stuart craft projects.Home Theater/2 Channel:
