Sockets gone bad?

Ryan	Sockets gone bad? I know I've posted on here numerous times in regards to the V4 I've been tinkering with in my free time from school. In short, amp was purchased and working and soon after fried a resistor in the power amp section (plate if my memory serves me correct). Amp was taken back to the store where new resistor was installed but they neglected to notice the lack of volume and glowing tubes. The two closest to the center (1 half of the PP) glow red if you start playing. Voltages were all good. From the phase inverter up I've replaced all the tubes and componants on the board and added some grid stoppers thinking it might be parasitics. That left the transformer. Talking to a tube guy he said I could swap the leads for a second to see if it went to the other sockets. I did that and disconnected the NF lead but it's still those tubes that glow. I'm looking towards the socket since I seem to have done just about everything short of buying a new amp. Could they be the culprits? Thanks for your patience and wealth of knowledge. Young and still trying to learn, Ryan
