This is similar to another question below but I didn't want to hijack the thread as it refers to slightly different amp.
I have what was supposed* to be a matched set of Psvane KT 88's in my VTA ST 70. I have three of the tubes biased at 49-50 mA but one refuses to go that low. It sometimes sits at around 55 and this morning is reading 64mA.
The amp sounds great. Should I worry about this? I have a couple of sets of EL34's I could use but I have to admit the 88's look really cool. Also, the system sounds better now but I also have a feeling my system is just breaking in.
* Too late to return. To Hong Kong.
EDIT: I forgot to add that I tried squeezing in the pins the pins on this socket.
