KITS just about ready

AntiCrapAntiCrap
in Analogue
The power amps = 5W SECA, 15W PP B class, 30W A/B all design based on chassis from Amazon.
The complex and bit was to design a PCB that did all 3 version thus reducing R&D cost from thousands to £500/
SECA Pre being done now by Quickie.
Normal Pre ready just trying to find nice chassis 
The Amps are all leaded no SMD.
BOM and cct available on request.

    Muy interesante Snr. Uno-cuatro.

    I'm wondering on the 30w A/B and the SECA pre.
    Shame the SECA in only 5w as I need more power Scotty! (I currently have a 15w A class... a snadge more would be perfect).

    All through-hole, oh sweet Mary mudder of Jeesuz, thank you! Eyesight can't manage SMD anymore.

    Clive Meakin asked the same, so as a mono half slave it can get 16W SECA but heatsink will get to 40C at a room temp of 22C

    Just completed all 4 versions of the KIT PCB.
    5W SECA sounds amazing caps 2 off 47,000uF
    SECA A/B amp caps 2 off 22,000uF 5W class A 15W class A/B gives 18W Build this one Paul I put mine in chassis you sent me THANKS
    A/B 15W Amp caps 2 off 10,000uF gives 18W
    A/B 30W Amp caps 2 off 10,000uF gives 40W
    Tested on Mintrals and Ruark Sabre, all stereo.
    When next chassis come will do bridge balance in version at 80W A/B 10W A class.

    When you come to set them up A/B bias first at 100mA and SECA at 1A.
    Also adjust DC bias to less than 1mV

    Have fun
