Can we refocus:
Want ti replace the Power Tubes in my CJ Premier 11a with NOS 6550. Don't want KT88, KT 90 or any other tube type. NOS 6550 only.
I am told the amp was originally voiced with GE 6550a. I have located those as well as various NOS Tung-Sol. Goals are more bass but "tuneful", NOT "Thump, thump", extended frequency but NOT fatiguing or over etched, and "magic midrange, more like EL 34, with longevity and reliability. I am presently using Russian "Tung-sol 6550."
I'm ultimately going to replace the signal tubes as well:
V1 and v2 are 5751
V3 and v4 are 6FQ7.
Suggestions please from those who have actually heard tubes in this amp...and remember please don't suggest substituting a tube type.
Also any experience with:
Vintage Tube Srevices
and/or
HiFi Town
Thanks!
