  • Reverb tank connection location for Polytone Mini-Brute III/IV (newer model)??

    Hi all -- new member here -- as I had my Polytone open on the bench, the rear panel fell down and ripped the connections for the reverb tank off of the board.

    The problem is I have no idea where they belong! I've done minor repairs but I'm far from an electronics expert and it's fairly labyrinthine on that PCB -- would anyone happen to have a photo of that PCB with its connections intact?

    I'm having trouble reading the schematic :/

    In case it makes a difference, it is the newer model with the sonic circuit.

    Thanks so much in advance!

    I can provide photos if needed.

    Welcome to the place.

    Have both of the wires been pulled off of the board? Those new boards are pretty messy and as I remember them there are no terminal markings on any of the pc points.

    Try and post a copy of the schematic here and a photo of the pc board. Somebody will be able to help you.

      Bill, thanks for the response -- after much scouring with a flashlight, it looks like it belongs on E15 and E16 as per this schematic: http://schems.com/bmampscom/polytone...I%20-%20IV.pdf

      (There were some wire fragments in the solder points, it's not blind guessing )

      Now I just need to find my soldering iron and find an itty-bitty tip for these tiny points.

      Thanks again!
