    Hi
    I´m about to complete the installation of the Juno 66 upgrade on my Juno 60 (the old version).
    I want to add the extended Filter Range Mod. The capacitor job looks easier. But I´m not sure about the resistor change,I´m not familiar with SMT . But you mentioned a Through Hole Resistor can be soldered across the existing SMT one which located on the Juno 66 board.

    So: Do i solder a resistor in the green dots position on the picture?:

    if so , which resistor do i have to use?

    Thanks

    A 27k or 24k resistor would work.
    The green point on the right looks good, but you will probably have a hard time soldering to the left. Better to use the resistor’s pad on the left.
    Maybe the best option is to send it to us (if you are in Europe) or find someone who can just replace the resistor..

    Hi
    Thanks helping.
    I´m in South America so…?

    Would it be ok if i scratch the left trace a bit , as if i was repairing a broken trace , and make a solder point in there for the resistor?

    Thanks again

    Yes that would work

    You can also get a smd 0603 resistor and just solder that on top of the other. It is not much harder than soldering an tht resistor.

    Thanks a lot!
    I can´t wait to try the Juno 66. I already placed the socket. But before doing the last steps , i´m cleaning everything , key contacts, and fixing some switches issues.

    Hi, just one more thing please,

    I just checked my Juno 66 board closely and see that, in it, the mentioned SMT resistor is a numbered: 1003. While in the upgrade instructions picture says: 01D
    also, my kit came with a 100n capacitor already.

    Does it mean i have the 20K SMT resistor in my J66 board already? it was bought on 2015
    Please see the pictures:

    Thanks

    No. 1003 means 100 *10^3 = 100.000 = 100k

    You got one of the very early ones. Must have been the first batch!
    We are now at serial number 1000!
    Awesome.

    Yes, it´s old, i took me a while getting back to this project. Moved from one continent to another, with all my gear and projects. I bought the Juno 60 for GBP300. It was seriously in bad state . Got the parts , replaced all the sliders etc.

    So i´LL add the 27k across the SMT right
    Thanks
    Ric
