Spot the mistake!

This a photo of the filter caps from a Blackface Fender Twin Reverb that was recently brought in for repair. Note the early ’64 date code on the reverb transformer. The main filter caps have been replaced with Sprague Atoms. Can anyone see the error the previous repairer had made?

    Hi, I’m doing amp repairs up in Manchester.

    At a guess, I’d say that the cap on the right is the wrong way around

    That’s the 1st correct answer I’ve had!

    Probably a reflection of the number of people following our blog…..

    I just opened up one of these today.

    Planning on doing some work. Before that I’m just browsing and making sure I avoid problems.

    It’s an original blackface, never opened.

    It’s going to be fun
