    I checked out the design and looks to be very sensible - I don't doubt it will sound good.

    Thanks for taking the time to do that, Andrew. I am hopeful. Alan and a couple of other guys have said it's a pretty decent design at least. For 6 the PCB was cheap and the components have probably come in for less than 60 the Transformer is 30 so 100 ish. It's been a good learning curve so far.

    Cheekier Update

    After 6 hours at Alan's today, we have a fully Working phonostage.

    It's a lash up power supply but there is a board here for a power supply which will be made up in the future.

    Here's the pics from today

    Managed to get a good couple of hours of listening and I am very surprised at how good it is!

    Very very nice midrange and extended highs. The bass is hard to judge because I'm experimenting with a new cartridge but it's very Rich and textured.

    I have some hum which wasn't there on the bench at Alan's, so I must have an earthing issue somewhere.

    Is it worth re-boxing in to a nice enclosure?

    Definitely. It's hard to imagine putting the Jolida back in at the minute.

    Huge thanks to Alan! Without his help and tutelage (correct spelling?), it would never have made it to a working unit!!!!

    I'll post the pictures of the re-boxing when it takes place.

    So is this the birth of a Bigbottle or Fireman80?

    Hahaha BIGbottle. That made me laugh mate.

    No, it's a PCB made by Valve Wizard. I can't claim any creative input on that. I just did it for my own experience.

    It's been very cool. Great sound I'm getting too.

    Whoo hooo

    Yes I thought it would sound rather good with the Decca. It's a very good design, preferable in my eyes to the EAR 834 clones.

    For anyone thinking of building this don't forget to bias the heater supply up to 60-70 volts above ground to meet heater to cathode limits.
