Range V2

    Hello, I have a problem with the range.
    I have the V2 PCB. There's no wiring diagram for this one. Even if the circuit is very simple I have some doubts.


    Some months ago I worked on this project, but I couldn't make it work.
    Now I decided to start working again on it, and I'm not sure what is going wrong.
    Here's an image of my current wiring: https://ibb.co/HzmMSZL
    With this, I get a constant interference noise as output. If I play the guitar I can hear it, but very low.

    Some things:

    1) the transistor is working fine, I have tried it in another rangemaster I have.

    2) I suppose the GND and +9v are the input from the power supply. I have attached a battery clip for this. I believe the AC125 transistor that came with the kit is a PNP transistor, so ground shouldn't be positive? In this case the marks shouldn't be -9 and GND? I have wired the batter clip in both orders, but I get the same result.

    3) I broke the original 10KA potentiometer and replaced it with one marked 10A 10K .. is this the same value?

    4) Maybe the first time I wired it I blowed the diode because reverse polarity? Can I replace the original (1N4007) with other similar?

    5) I did a basic wiring for the input/output jacks, but this shouldn't be the problem as I have done several effects before and I always start with this layout... still, maybe I did something wrong here?


    I have no clue how to continue with this, I appreciate any help.
    Thanks in advance

    Hi,

    Some Tips:

    1.:Transistor is working,but did it work in this Circuit? DC Measures?
    2.:Yes,Tranny is PNP,but Circuit is based on negative Ground,take a look in the Shematic.
    3.: Should be the Same.
    4.: You can replace in with any other Type of 1N400X,the be different in Voltage Ratings,but all of them high over 9VDC
    5.Yeah,you had to check if the Circuit is working,beginn with the Tranny,DC Measurement,if it works,it will be helpful to use a Audio/Signal probe to check where you Signal goes t and where it stucks.to check it,use simple in/ out wiring without True Bypass Switch.

    Last,but for you first after Measuring: Check your Component Values and orientation,check Traces,check Solder Joints !!!

    For additional help,take some High-res. Pictures in Detail of Solder and Component Side and full Wiring.

    best regards,
    Micha
