I just retubed the output tubes on my MC275 Mk VI (see my post on Psvane tubes).
I just checked KT 88 tube temps with an infrared thermometer and temps are all over the place. From left to right, V8 is 130F; V9 is 230F; V10 is 290F; V11 is 321F.
Is this normal? Or do I have a bias problem? Or is this a tube problem?
The vendor tested these tubes before sending out and they are within 5% for Ip.
