The cover I've bougth somewhere on Ebay, the main case is from Hammond and the two things as P3 jacks (I can use the RCA´s with my HT or the P3´s with a headphone).
First time I used a transformer (the top cover was higher), but I changed for a simple 12V psu and trim a bit the cover.
Instead of FET´s I used an OPA2134.
Before was like that :
The paint was getting blemishes, so I change to an automotive one.
