NOS tubes For my Rhea


It looks like I will need to replace the tubes in my Rhea.
I have been hearing a sporadic “rushing” sound from one channel on my system. I suspect it may be tubes in my Rhea OR Calypso. First off I do I determine which unit is the culprit (I only use one source – Turntable) . Also who is the best dealer (best prices) for tubes. I am very untechnical so I need help and advice. Thanks!!

"has anyone bought tubes for the Rhea (or anything else) from Upscale Audio???"

Yes, this past fall I bought 5 Telefunken E88CCs for my Symphonic Line pre from "Uncle Kevin." He was extremely informative about what the various 6922 family tube flavors would provide when I spoke with him about options.

And when one tube died within the 90-day warranty period, he replaced it without issue. So count me as a happy camper.
Thank you all for your responses and advise! I must say that both Brent Jessee and Andy Bowman were so helpful.....I made my decision.
Now I have another question that I will post on a new thread.
Hi all...I am looking for the contact number for Aesthetix but can't locate them. Anyone have it???? Tks!
Well it’s been approx. 3 days (9-12 hrs. ) of listening . It’s amazing how new tubes could make such a significant difference. The top end on my RS 1-B’s is more delicate and shimmering and yet the mid-range and bass has much more meat on the bone then before. Enjoying the new tubes and a big endorsement to Andy Bowman of Vintage Tube Service. Now I need to think of re-tubing my Aesthetic Calypso!!
