My '03 Ghia has a voracious appetite for V1 preamp tubes. Halfway through our gig last night I had to replace the third one in about two months. These are NOS tubes so I'm inclined to think it's not bad tubes. Any ideas?

Have you tried cleaning the tube sockets with DeOxit or another cleaner? I'm wondering if the tubes are just losing conductivity to the socket.
Have you confirmed that the tubes are "dead" by trying them in another amp or in another position in the Ghia?
Again for the hundreth time I concure with Steve. The Chicago made black " Connector Corp." sockets don't hold up as well as some, especially in a 10 year amp in position V1 that may have lot's of NOS tubes swapped in during tone tasteing sessions.
You can eliminate that problem by installing a new Belton ( brown) 9 pin socket, if in fact the socket is the problem. A loose socket will cause problems like you are having .
Also don't think that what is left of NOS 12AX7 are so superior anymore. I use about 600 pre amp tubes a month and refuse to purchase NOS 12AX7's anymore. Nothing left but stems and seeds for the most part, but slick tube salesmen will tell you differant when they offer you a $60.00 12AX7. The Mica spacers are 40 years old in a 1970 circa tube and quickly deteriate from use in a hot guitar amp.
But your problem does seem to be a streched out V1 socket, from the little data given.

GuitarZ: So, I cranked up the privacy protection on my browsers, facebook, etc. I have to say I miss the music ads and such. I really don't need ads for watches and other random stuff. Maybe the internet knowing me isn't such a bad thing.

Joey Beverages: hayesgary307 try a Z 210 or Z 410 with Galaxie ... also, yes the G1265 is most tasty and excellent

GuitarZ: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!
