does anyone know where i can get power tube retainers for the Tweaker 15 combo? I know there are some in there, but i cant find them anymore, and anyways they were for 6V6's, and on those they were tight. Im running 6L6's, and im finding that the longer, louder i play; they tend to work themselves out of the sockets a little. I tried a bunch of different tubes. It would be one thing if it was a head; with that i always had the back grill off so i could reach in there. The combo is much more difficult due to the closed back design, and the fact the tubes face outward on the other side of the chassis where the speaker is. So I can reach my hand back there and fumble around until my hand lands on them and i can push it back in, or make sureits in; but that's getting old quick.
