Reseating tubes
This morning one of my power tubes went in the 2301. I don't have a tube tester so I went with trying the 'process of elimination' method. Luckily, The 2301 makes this just a bit easier. The 8 power tubes per amp are grouped in fours. You can run the amp on 4 tubes for a short time to sort out which tube is bad. Once I found out which quad was defective, it was straight forward. I got lucky and picked the offending tube first try.
Here's what I found after reinstalling all the tubes. The tubes burn noticeably brighter on the amp where to tubes were reseated. So I reseated the tubes on the other amp and what do you know! Now these tubes are burning brighter as well. It's been 14 months since I installed these tubes. I guess it's like cables and interconnects, in that they should be reseated from time to time. YMMV Reg

It wouldn't hurt to use a little regular DeoxIT on the pins either.
