I have had an ongoing extremely scientific and formal survey of this issue (upgrading an amp to handle the instantly destructive utterly dangerous death hazard of 120s or 150s needing heater juice that will instantly destroy the amp, and all life within 11 feet) using informal and clearly amoral studies of data and nearly incoherent blather here and elsewhere. The results indicate nobody has experienced this issue and lived to tell about it…I had KT120s in my trusty 502p for nearly 3 years…replaced with KT150 last December with no issues except burnt fingers from adjusting the blinky light bias screws. The current score in my survey is as follows:
No issue with unmodded amp using 120s or 150s: 317,412.
Issue with catastrophic amp failure after which there is no reason to ever trust in data from posts like this one: 0 (zero)
