I'm working on a 1971 Twin Reverb.
6 of the film capacitors are blue blobs, which I am familiar with.
3 of the film capacitors are light red blobs. I have a feeling these are from the factory also, but would like someone to confirm this.
However, there are 2 film capacitors (22nF) which are a dark red with a shiny surface.
I have a feeling that someone has installed these as replacements, but I wanted to check in case anyone has seen these in a stock Fender amp.
Does anyone know what they are?
