Please note that I have never found a single reported case of KT120s overheating any transformer anywhere ever at any time in the history of the universe....and I've asked around. I'm using 'em in a Jolida amp and they sound killer compared to the fine stock 6550s and an also great sounding set of Sovtek KT88s. I just love them 120s!
KT120 tubes in AudioResearch ref 300 MK2
Hi
I own the ARC ref 300mk2 mono-amps and i wonder if someone have any experience with replacing the powertubes for the Tungsol KT120.
More specific: Is there enough room because the KT 120 is a bit bigger?
Does it gives problem with the heat?
Is it necessary to replace the filament-transformer,
because the Tungsol needs more current?
What is the soundexperience?
