Reliability issue - Nagra VPA power not KR tube

I have a pair of Nagra VPA Type I on evaluation. I ran over the weekend. The chassis heated up to well over finger warm. Tubes are obviously very hot - 535 F. My friend that has had a pair for 4 years recently had a major issuethat costed him $ 2,000 to repair. As part of my evalution, I am curios to hear from other VPA owners, what reliability issues they have had and the costs to repair them. Are these amps one should avoid from a reliability point of view. Thanks

in term of 845 tubes, I've tried 3 different pair in my system (Mastersound Reference 845/Italian). I tried the new 845M and was totally disapointed by the sound. Then I switched to Fullmusic 845 ($820 for quad) and got disapointed as well.
My current setup is using Valve Art, which I'm very satisfy with the sound. However, these Valve Art are getting to old so time for replacement. I just recently ordered 4 845tube from KR, let's see what's the result!
