    Hi,

    It's my first post here, I'm trying to find schematic of 3BF for Deluxe 85 but it's quite hard ...
    After a research on the web about footswitch schematic I find schematic of the amplifier but no way to find one of footswitch.
    I've found by the way parts list for the footswitch... So here is the parts list for pn 0028146000 (footswitch of Deluxe 85):

    S 1,2,3 - Switch push SPDT - n.3
    J 1 - Jack phone mono - n.1
    CR 1,2 - Diode 1N4448 signal 75PIV - n.2
    LD 1,2,3 - Led red 5x5 SLB-55VR3 - n.3
    CR 3 - Diode Zener 1N5234B 0,5W 6,2V - n.1

    Then I read a post from Tuuur a member of Tdpri and, if I am not wrong he had a Deluxe footswitch but with different Part Number ! More exactly it's pn 028148A.

    So... looking to photos of 028148A from Tuuur and using parts list of 0028146000 I'm trying to build this footswitch, but as I am not skilled in electronic and I have some doubts I would post here schematic and pics ... and if anyone here had some information or tips it would be helpful :)

    I've tried to sketch the schematic, does it make any sens ?

    - I don't know if LEDs are in the right direction
    - I don't know if I have choosen right switches in schematic, in the photo we see 3 pins switch and from de parts list ... it's push SPDT.
    - I am not sure about if In and Ground of the mono Jack are ok or inverted!

    Looking closely to parts list posted above 028148A of the Tuuur's PCB is very similar to pn 0028148-000 so maybe it's the same footswitch then 0028146000!
