Results for My ref C.
Have to say i am very impressed with the amp so far. Very detailed without being harsh and it has a great control. It also also very quiet.
In a way it sounds like a really nice hybrid of the Tripath and LM3886 chip amp sound, the detail of the tripath but without out the slighly fatiguing sound and and the body of the LM based amps but with more detail and better bass control.
I really like the sound though i might trying fiddling with a more exotic input caps since that really seem to have a very positive effect on my Amp3.
I am currently using it with Rudi's dc nulling version of the AD815 preamp. What are people opition of using it with active vs passive preamp. I found the preamp made a very postive effect to the straight LM3886 subber setup though it had a less obvious effect on the Amp3.

I found I prefer the my_ref passive.There is plenty of gain and dynamics.Mauro suggests a low imp pot around 20k.
Now I have tried two pretty good preamps -one is based on ad 8610 plus EL buffer in a Walt Jung type nested feedback circuit and the other is the Broskie Aikido which is better.But both slightly colour the sound and there is a loss of transparency even though some may like that they bring some parts of the sound a little more forward.But for me they subtract too much info.
I am seriously thinking of investing in a good TVC passive pre such as the Django.Too bad that it costs three -four times more than a my_ref.

A single ended Joshua Tree may be just what you are looking for. It works very well directly into the REVC as a passive attenuator, and the cost is quite a lot less then similar devices. The output impedance is a constant 750R and the input impedance in the worst case is about 2.2K, but for most of the range it is around 5K.
Cheers!

It would be interesting to compare a good step attenuator with a TVC.
At the moment I have a small Creek passive pre which is basically an Alps motorized pot.I also have an expensive DACT stepped att in the Aikido pre.But I have not directly compared the two attenuators.
Most people have preferred the TVC over simple passive resistive vol controls quite clearly although as I mentioned they would cost as much as a very good DIY active tube pre.

Hi Protos,
I have a TVC based on Stevens&Billington's TX, bought at Bentaudio.com . I think Django lacks the excellent OCC copper wiring, wich is a very detailed wire. You could build a TVC yourself for around US$650, I believe. I bought mine before (copper) price went up.
My "My-ref" is integrated with a Kookaburra and it is very detailed and controled
it costs ten times less than the TVC!
For a direct comparison between TVC and Kookaburra, I am waiting for my new "my-ref" monoblocks.
Cheers,
M

i was just wondering if anyone had swapped out the sockets and soldered the opamps straight in. Anyone done this and was there any aprieciable difference.
By the way the amp is burning in nicely. Been running it for a week staright and it is a different amp to when i first powered it on. Never had an amp change as much. Odd.

So how is the Oak case coming along?
My father helped me build my first car stereo woofer box over 20 years ago.. He 45'ed all the joints and made a wonderful box that he could be proud of.. It stayed in my car a week before I realized I made the wrong calculations and had another made..
To this day I STILL tell him thank you for taking the time to help me make my first box even though he thought it was "silly". He STILL thinks my stereo and electronics are silly .
I hope that Oak case means as much to you as my box does for me. No mater how it looks or sounds in time you will still remember the box long after the amp is gone.
Sorry to be all sentimental, but to me THAT is perfect DIY.. When you can work with dad / son..

Hi,
My parents have been in Canada for the last few weeks staying with some family friends (someone my great uncle servered with in the RAF). Also in live in London and my parents live in gloucestershire so i don't get to see then as much as i would like. Probably go there next week and find out what Dads been up to. He's just retired but has been a chippy for about 50 years. Should be a walk in the park for him but it will mean a lot to me.
Like you said that sort of thing is great cos it means you can spend time working with your old man and have somethign really nice at the end of it.

Hi guys,
I've just built a plain vanilla Gainclone...from the reports on this circuit's performance, I wish I read this first!
I assume everyone's in agreement that it's much better than the old GC (in whatever iteration)?
Anyway, I've never etched a board before and would like to have a go. There was a post way back with a link to the RevC board artwork, but the link is gone.
Russ, only if you don't mind - can I get a copy of that please?
I'm buying a kit anyway as you guys can source the components for about the same price I can but I don't have the hassle!
Ed, love the Mongo talk. I've been laughing all the way through this massive thread.
Cheers
Stuey

I'd love to get my hands on one of Mauro's new versions of the REV C, sadly he is not selling PCB's outside of Italy, and the assembled boards he is willing to sell start at EUR130... looks real nice... but a bit pricey after imprt duties etc for a pensioner...
EDIT stupid me... Might as copy and paste some of what he e-mailed me.
