I did a little poking around inside my amp today. I was able to significantly tighten up the output tube socket contacts. The tubes pushed in with little resistance in stock form and felt very loose. They're now pretty tight. Not quite as tight as my Rogue M180 sockets, but close.
I also changed the cheesy anode connectors and caps. The factory clips were very loose and cheap feeling. When doing this, I got a good look at the blue anode wires and I'm pretty sure that they're Teflon insulated. I forgot to measure them, but they're probably around 18-20awg.
