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?

Hi Bifwyne,

Thanks for your advice, i have had contact with ARC, they already told me not to do.

The reasons:
The filament-transformer is not powerfull enough.
There will not be enough space for de KT120.
The KT 120 is to heavy for the socket.
