Hi all, Silly question - Has anyone here tried the Russian TungSol KT120 tube in a Hiwatt DR405 or have heard any reports? According to the marketing blurb: New Sensor now announces the Tung-Sol KT120, which has a plate dissipation of 60 watts, making it the most powerful tube in the 6550/KT88/KT90 ...

Thanks,
Emil

A question he has asked me, whick I would like to run past you guys, is whether there would be any negative effect in increasing the 100uF filter caps to 200uF. I'd expect there to be less power supply rip...

I have a set of reissue Tung-Sol EL34's in my recently built VHR DR103 and am extremely happy with them. Lots of room shaking bottom in those while still sounding rather crisp.
