    My board is here as are the JFets. It will be a while before I can get to this. A vpp amp build is ahead of this and were headed out for a 3 week road trip

    And I just opened the package the pcb are in. Man, a fella could have this breadboarded in half a day. I need to take a closer look at build threads.

    Slowly but surely, step by step, inch by inch. IEC will be changed and the centerpiece of White Oak will be modified. DSC_0039.JPG DSC_0038.JPG

    Great work. The Alpeh J looks good. Those 25watts of pure class A should sound great!

    Kind of reminds me, aesthetically, of the Pioneer Series 20 M-22 Class A amplifier of -- a long time ago

    My SE 45 amps are not a good match for the Jordans and in the meantime, I'm using class D as pushers.

    I’ve got Aleph J on the brain...

    Have either of you guys finished your builds? @opa1 @inthewoods

    I have to get my Avondale’s finished first and I’m part way through a Michell turntable rebuild for a friend but as soon as they’re out of the way I’ll build the F1.

    Got sidetracked, Anthony. My Jordans like a bit more power than the J put's out.

    Inthewoods, any chance you can give me the dimensions for those heatsinks? I don't think they need to be that big for my F1 but it'll give me some idea.
