Get some socket savers. They come in 8 or 9 pin. Before you put them in just squeeze the female pins a tad and then stick the socket saver in so it fits tight. Now you will always replace your tubes in the socket saver not the sockets on your amp. I use them on my amps and they solve the problem.
is there a way to tighten pins in tube sockets?
Two of the output tube sockets of my VAC amp don't grip the tube pins tight. The tubes are Winged C and I have several sets and all exhibit the same looseness. Before I send it back to VAC, is there a way to tighten the pins?
The problem I experience from this is a right channel hum and unstable tube bias.
