Aric Audio Systems Unlimited Preamp

@grannyring much respect to "The Dude" and thank you for the insight on it’s uniqueness! In terms of similarities the ML has the breaker power switch, an exclusively film capacitor power supply and robust storage + PI filter stages. I’ve also employed SS rectification using dual series UF diodes per leg with snubbers across them in a full wave bridge, and perhaps a difference (not knowing the Dude architecture myself), is a large 5H choke after the first filter cap stage for smoothing. This uses a more conventional Mu-Follower stage with a 6SL7 as the amplification. TKD volume potentiometers, and Duelunds on the outputs (Jupiter PIO’s are used in the phono stage section). It’s fairly straightforward but does use a pair of OC3 regulators snubbed with small film capacitors to drop the excessive voltage at the tail end of the B+ before it hits the plate resistors. While there are many differences I’m sure, and this is not out to "clone" the design, I would more respectfully say this pays homage to The Dude in it’s basic structure. Best regards, Aric

Goodness I love what you are doing here. It will sound absolutely wonderful I am sure.  Very nice.  Love to see pictures if possible. 

Based on the pics of the Motherlode I've seen its a beauty. I don't know enough about the workings of all those impressive looking capacitors and such inside of the units to really appreciate what Aric has created here, but if it sounds better than the linestage he built for me ( and I'm sure it does ) this will be one sweet preamp. Can't wait to hear laaudionut's impressions of it. 

That sounds like a wonderful piece of audiophile gear. Love to hear more about the specs. Knowing Aric's attention to details and his choice of excellent components, I have no doubt it'll be a great success. Even his lower end Unlimited preamplifier that I have is excellent and sounds better and better the more I use it.

I'll be able to post more a bit later- perhaps Monday as I had some company arrive for the weekend. Real quick though, is anyone aware of an easy way to post pics on this forum without having to upload them to another site and post a URL?
