    The boards are long sold out and can now only be picked up from people who bought them and are selling them on. There used to be quite a few available this way but they are now becoming rare and don't come up often.

    Simon used to let potential customers try his but I don't think he's planning on building any more.

    2 Improve listening room.jpg3 TT and arm worthy of paradise .jpg4A who is going to complain .jpg4Bwork in progress .jpgAll I need is same BC337_40.jpg

    Do not despair options are :
    1)Ask on Diyaudio
    2)ask Simon
    3)wait a long time for some one to design and make new boards

    I did a first sketch and print of the boards a couple of years ago posted on Diyaudio Hessener comment was that is a very tight input stage
    I am still working on it and made quite same progress

    1) get rid of GF . Done
    2)improve listening room . 95% need to isolate the wall whit neighbours but that can be done later
    3)get new TT and arm worthy of paradise
    4) sort out end of chain to be worthy of new TT and arm ( this is constant work in progress just got a pair of Daly Rubicon on loan from Dogodaudio Liverpool
    5) obtain a decent number of BC337-40 to finish populating the R3 boards I had on the bench from 2 years ago and that where started before point 1 of this list became the main priority as remaining point 2 to 5 would not have been possible .
    6) once R3 boards whit Calvin Buffer are completed dig out old drawings and restart

    As you understand it is a slow process for example the next stage point 6 will mean design and build a few prototypes and once that is done and working I will find a decent professional studio to make decent boards
    7) Get decent boards made
    8) make a lot of peoples happy and a further lot not so ...

    It is going to take same time work and money, SEE 1 and 2 where 2 is buy new house whit 15 ft X 16 ft living room, but once U listen to Paradise for the first time I am sure you would agree that it is well worthy

    Another option is to wait until I begin making a phono stage which works on the same almost unique operating principle as the Paradise in a few months time.

    Are you going to use the alternative output stage?

    Also, interesting choice of capacitors in the RIAA - any particular reasons for that combo?

    Edit: oh sorry, just read your post properly and I see you are going to add the Calvin buffer boards .

    Simon,

    Is that a HiFi-2000 / Modu case?
    I was looking for a full size Alu case to house the dual PSU but can't find one exactly like I want.
    Can either find the size I want in steel or smaller than I'd like in Alu.

    Far above what I can do, my knowledge of electronics is limited to welding and bashing
    I was thinking about using complementary Toshibas for the mirrors as they do not have such a wide HFE span as the not so complementary BC337-40
    I am sure the PSU would also benefit from a re- design maybe use Zen Mod Shunty
