    For the OD2 To OD1 mod, did I change components on the wrong Board? This is the pic of the main board. Is it the board the knobs are attached to? IMG_20200813_215532065~2_copy_2000x1500.jpg

    Drop the soldering iron and walk away

    If you're clueless, then you shouldn't be holding an iron

    Not sure, I think you're in the right amp though.
    I wouldn't drop the iron, If I dropped my guitar the first time I made a mistake I would have only played for 30 seconds instead of 30 years.

    This PCB style board is probably not something a beginner should go for, but anyways OP should be able to read a schematic and identify his amp before proceeding

    well I'm not completely clueless I've been a commercial and industrial electrician for 20 years I just have not had to go through basic circuitry since apprenticeship class I had a simple question there's two boards on that amp your response sounds like someone who's actually never picked up a soldering iron before. That's why in the jvm forms they tell you what number of component to change I did not realize the front control mounted board had the exact same number designations.

    Can you read a schematic that's my question . It would be very easy for me to be like you in just fork over some money for a tech to do the repair for me but unlike you I'm actually going to take the time to try and learn something new and not just flex my muscles in a forum.

    Printed circuit boards are not easy to trace things out that is the problem . The traces will lift and fall apart if worked to much . The best thing to do is put back to original . You can build a 2204 ptp board and all the mods you want

    I can read a schematic and build my own amp from it, not to worry. But only p2p I don't mess around with PCBs.

    Maybe the issue is that you didn't provide us with all the info you got. You basically show a picture with a few circles, how can you expect people being helpful from that.

    Not all questions can be answered by just anyone. People with the answer will respond to that question. I don't try to answer questions if my knowledge isn't pertanent to the subject.

    I've been here several years and never had problems. I know most of the regulars. Didn't mean to be so brazen but Im not keen on opening with sarcasm either. Thanks anyways though. Have a good weekend.

    It's my fault really, if I had of looked at the schematic and followed the OD circuit path instead of open the amp and immediately see the designation numbers on the first board I see I wouldn't have made the mistake. My joints are really clean so no major deal to pop the original components back in and do it properly.

    i found i wasn't teachable until i had the humility to admit i may be in over my head and accept suggestions without getting defensive

    first amp i ever tried to mod was a dsl with the Joey mods and ended up destroying an already non-functioning amp, so i get it
    before i even plug the iron in I've thoroughly gone through the schematic, compared the device in front of me to the schematic (they're not always the same!), and possibly even marked the solder joints in going to desolder with a sharpie. that whole measure twice, cut once thing my father always tried to teach me that seemed like needless time wasting as a yout

    Before I started building amps I spent three years in night school. And that is just the beginning of it . We all have projects that don’t work that is part of the game . But you will get better the more research you do the better of you are
