I have a 1974 Session 400. I bought it new that year. Over the years it's been serviced which required pulling the plastic Molex connectors from the circuit boards. For 50 years, I would have to occasionally remove them and try to squeeze the female connectors to get better connections. Lately, it's been cutting in and out. I finally bought new female and male pins and replaced all of them inside the plastic connectors. Instead of crimping them as the factory did, I did soft crimps, and soldered the wires to the pins and reinstalled them into the plastic connectors. Amazing difference. Totally quiet and full power again. I did a capacitor mod upgrade in 2013. I also, upgraded the power transistors to the ones used in the Nashville 400. If you're having to pound on the top of your Session 400 to get it to act right, I highly recommend re-pinning the Molex connectors. I have a flat spider magnet 1501 in it. Great tone.

| It's a shame that Peavey used the Molex system. I had to deal with them in older Ford and Chrysler vehicles. I once complained to the Ford service manager, he told me "they made it way out of warranty before they gave problems" The same is true for Peavey! |
