This was one of the reasons that HP eventually went to the DC oven controller. Even the early 5061A had this same problem. The 5060A and the early 5061As had an AC oven controller. When they changed to the DC controller, it probably saved a lot of people from insanity. some of the other reasons were the transformer taps that had to be changed when a new tube was installed, parts issues improved design, manufactureability, etc...
