    Have you contacted GK? They've always been good to me as far as providing schematics.

    I just rebuilt an old similar Dynacord MCX24.4.2. I couldn't find a schematic, but they are pretty straightforward mixers. Nothing fancy. Separate cards for each channel, which is something you don't...

    Sorry, but that's not going to happen because of a number of things. Google and read about the "Fletcher Munson Curve" for one. Also, depending on exactly "how loud" you're talking, some of your...

    Ok. Saying first that replacement is best, when you can't find parts, you sometimes have to improvise. Try taking the pot apart and giving the contacts a slight bend/tightening. It often works.

    From the picture, it looks like the reason for replacing the 10k pot is that the shaft is broken. If that is indeed the case, take the wafer/contact portion off of the 10k pot and put it on the...

    NOTE: Without a schematic, this is a bit of generic info and speculation.

    My first suspect would be a shorted op amp on the channel with the pegging meter. On many of these machines, the inputs...

    I'll add, if you remove the screen to clean up the area and re-glue, be careful that no chunks of old glue or other debris falls into the inner workings of the speaker. It only takes a small chunk of...

    So thirty bucks less per piece of "The Nevets Collection"? That could be thousands of dollars. ;)

    The shi+ of it is that nobody's buying anything right now (except apparently toilet paper). It's a bad time to unload gear. If we could help find a place to store it, the eventual outcome would be...

    This makes me sad. Believe me. I'll be stewing on anybody I know in the area that could store your gear for a while. I don't have a lot of contacts in your area, so don't hold your breath, but my...

    ^^^^^^That! It almost has to be a triggering/measurement error of some kind. If phase was actually flipped on one side making the two outputs in phase, there would be no voltage drop across the load....

    Yep. I wasn't meaning specifically that design- just using it as an example. In other words, find a SS reverb circuit you like and copy it. There are plenty of examples out there.

    If you're looking for a Blues/Rock sound and have no pedals, I'd dime the amp.

    It would help to know what kind of music you play and what tone you're after. Blues player? Clean jazz player? Metalhead?

    Those look like tantalum caps to me- not ceramic. Aside from that, no comment. The internet is full of "what caps sound best?" debates. I won't start another one.

    Of course leaky caps effect tone. A leaky cap is no longer a cap. It's a resistor. You can't expect the circuit to work correctly.

    You could copy the reverb circuit from any number of amps with a SS reverb. The Fender Hot Rod Deville or similar might be a good reference.

    Monitor voltages. Do any of the supplies disappear when the amp stops working? What is your bias current? Are tubes red plating?
