I put together a power supply for an old Sony PS1 for a local guy. I did a little load testing last night, seems to be fine, no overheating issues. Chassis is a generic Chinese amp chassis, which was originally used for a Hypex NC1200 amp.
I used a Neutrik 4 pole speakon connector for the output, one pair for 3.6v and the other for 7.6V.
It has no tubes, please forgive me. ;)
