My expensive Mullard CV4004 (driver tube) just developed a crack and bit the dust today. Pulling out "Getting the most out of vacuum tubes" by Robert Tomer, I found out that the most probable cause for the crack are the tight tube sockets. The contacts on the tube pins are supposed to float within the socket so that they will not put too much stress on the glass envelope. The contacts in the sockets on my MG Head did not seem to float and the tube is quite tight in the socket. Think thermal expansion and glass stress everytime the tube heats up and cools down.
Has anyone else experienced this?
