Replacing 6550s with KT 88s

Rodmann99999
Many thanks for your response.The 6550s are due for replacement. Nearly 3+ years. Not sure how many hrs but I guess it would be close to 3000 hrs. I prefer a cleaner sound to a warm, mushy "tubey" sound.
Cheers

I am curious about what changes you found using the NOS GE 6550s as compared to the Winged C 6550s. It may be possible to get a quad NOS from Singapore.Incidentally what power amp are you using?
Many thanks
Pradeep

Hi Joe
Many thanks. It's advice and insights like yours that makes Agon such a
great resource and community. For a tube novice like me this is invaluable.
Enjoyed reading your blog and will post my impressions post acquisition of
a new set of pre and power amp tubes which should arrive ,hopefully within
the next 10 days.
Cheers

Many thanks. You are absolutely correct.I intend to do this slowly and in phases to try and guage the effect of each tube. Am interested in your comments/experience of the NOS 6550s vis a vis the Winged C current production
Cheers

Thanks that seems a sensible way to go as the price differential between NOS and current production for phase splitter and driver tubes, at least in Singapore , is much lower than the 6550 power tubes.
Will post my impressions post makeover.

Check out the Well Audio Labs (Singapore)site. I reckon the prices are competitive vis a vis some other online sites.

I procured a set of Genalex KT 88s from Well Audio Labs, Singapore,last week and spent the better part of the weekend comparing the 3000 hr+ Winged C 6550s with the new KT88s.What immediately struck me was that despite some 3000 + hrs there was little to choose between the 6550s and the KT 88s. There was a smidgen more smoothness and air in the upper frequencies. After extensive listening comparisons done with NJ-Come Away With Me lp, the KT 88s are superior in the context of my system and my listening preferences.
Many thanks for all your input/advise.
Happy listening
