Description

Just completed this second system for my Acoustic BBQ office space.  This is where I make my cables.  Since I spend I lot of time here I wanted some good sounding tunes! This is pretty much a complete DIY rig except for the Magnum Dynalab tuber and Roon Rock server. 

DIY EL86 PP amp with 13 watts per channel.   Tube rectified with all film cap power supply and nice top mounted Hsmmond chokes. Mundorf film power supply caps, Jupiter copper foil coupling caps, vintage Scott output transformers, Cardas and WBT connectors, Duelund and Neotech hook up wire, no electrolytic caps anywhere, star grounding, Mills MRA and Takman Rex resistors and fuseless as I used a nice on/off circuit breaker instead.  Sounds marvelous! 

DIY 6sn7 line stage based off the Tube Research Labs Dude preamp. I call it the Son Of A Dude. This baby has a massive CLCLCRC Pi filter power supply using all film Clarity TC caps.  These are the better 4 lead out wire Kelvin style caps. The chokes are Hammond as well as the over-spec’d power tranny. 5u4 tube rectified, voltage regulated, Mills MRA and Shintok resistors, Jupiter copper foil output caps, Tent Labs heater supply for the 6sn7 fills, 48 step shunt type stepped attenuator from Khozmo and again no electrolytic caps to be found. 

Wonderful sounding preamp that I am considering offering as part of my Acoustic BBQ line of products. 

All cabling in the system is my Acoustic BBQ brand.  

I made a nice power distribution box using Duelund 600V 12 gauge polycast copper wire, Pangea outlets and a DC blocking circuit.  All gear plugs into this box. Audience XO caps are also placed across the outlets for filtering out of noise. 

My DAC is a simple Eastern Electric Junior with many mods done to it. 

Speakers are Aurum Acoustics Leisure 2 Signatures on 36 inch Pangea stands. 

Just a nice intimate sounding rig that has wonderful warmth and musicality.

    I love Deja Vu tube gear.  Nice! I am going to look at your rig again.

    Nice Bill my EL34  amp, by Deja Vu Audio, uses an old Accrosound output transformer it sounds great. Not sure about the other transformers but it has some chokes in there as well. Good luck with your next build!

    Good question. I used some nice vintage Scott output transformers in the EL86 amp. The rest are Hammond power trannys and chokes.  I used bigger and more expensive chokes from Hammond.  300 series power tranny on the preamp.  Overkill, but I like the 300 series much more than the 200 series of Hammond power trannys. The 200 series seems to always buzzzzzzz.......mechanical buzz that drives me crazy! 

    I am going to build a SET amp next and will look at using other trannys and chokes for that build.

    Bill another cool looking system and great looking DIY gear. Since you are such a parts perfectionist I'm curious what transformers you use when you build your own tubed gear?
