M mkane New member Jul 9, 2015 #2 Problem solved. One of the tubes was bad. Glad I bought a few of those Mullard's.
P Paul Joppa Moderator Jul 9, 2015 #3 It might just be corroded tube pins or a poor socket connection. Always worth checking!
B Bonzo New member Jul 10, 2015 #5 Plugging in and out the tube several times can clean a bit the pins. Ciao!
