Next stop is replace the film cap. These square ones fits better on one side. I made a case for it so the idea is to clip it on to the headphone jack and the corner screw of the transformers so I dot have to drill any hole.
Very important you have good clearance around your capacitor terminals from the metal securing band and preferably insulate the connection as well otherwise there is a very real risk of your top plate becoming live if the capacitor moves even a milimetre or two during normal moving and handling movements.
Maybe it's just the angle of the pic but clearance looks pretty minimal from the picture particularly at either ends
Neat way of securing them other wise.
