Differences in tubes.


Can anyone tell me the differences sonically between kt77s and 6550s? I know a lot of is dependent on the circuit the tubes are used in. I'm using a Jolida 302b with 6550s in it and was thinking of trying kt77s for something different.

Thanks in advance for any help!

I was also wondering how the KT-77 compares with the KT-66 tube? I'm also a fan of the EL-34 tube. Beautiful sounding mid range. I've been considering the Gold Lion tube. Running with Quicksilver amps...Thanks...

If you're still using Triangle loudspeakers, you may want to call Kevin Deal at Upscale Audio in SoCal (see the A'Gon Guild). He's a Triangle dealer and (I think) a Jolida dealer who specializes in tubes/tube amps and may have some useful thoughts for you.
