  5. Technical Assistance/Advice Thread

    in Do It Yourself

    Posted · Edited by lkong

    Working on build a water cooling Uberamp.

    Snatched a cold plate off ebay.

    I'm looking for advice to mount the transistors. I dont think I should drill and tap into the cold plate.

    So I have 2 option:

    1: 1/8 by 1 copper plates drilled to mount on the cold plate and sandwich the transistors in between.

    -----copper plate-------

    -----transistors----------

    -----cold plate-----------

    2: mount copper plates directly on the cold plate, drill mounting holes on the copper plates, counterbore the back side (the face contacting the cold plate).

    -----transistors----------

    -----copper plate-------

    -----cold plate-----------

    Any suggestions?

    Here's a planned layout:

    You should be OK, assuming you are using the right adapters (don't use the SA1349/SC33xx adapters!). There aren't really any voltages present there that would damage the JFETs, unless the Gate is wired incorrectly.

    What worries me is what caused it, I simply tested the amp with 1k sine wave. I hope it's just the input jfet.

    That's certainly one approach to amplifier placement.   The subs certainly aren't going to walk anywhere.
