Thank you, all!

I greatly appreciate the options you have given me! 

All the best,

6550's...  How about a slightly more powerful tube as in a KT88 or better yet, a KT90!  It's only money...hah!  :)

Upscale has restrictions on tube sales (read the descriptions).

I bought from Tube Depot before. They were intelligent to talk to and the tubes were shipped quickly.

TUNG SOL - $86,95 EA.   UPSCALE AUDIO IS THE BEST SOURCE FOR VACUUM TUBES.  TUNG SOL ARE EXCELLENT TUBES AND QUITE RELIABLE

fan of the tube store.  ordered a pair of 12ax7s for phono preamp.  called first to consult, as I wanted lowest noise tubes available.  was steered towards a product that was well below their highest priced tubes.  

Go wild. They test them too. Ask ‘em.

You can buy Sovtek 6550 tubes on Amazon....they have some in stock now.

I've bought tubes on Amazon and they worked just fine.

A few days ago I bought a Svetlana 6550 tube from the Tube Amp Doctor in Germany.  

I paid $150 total including shipping for it...it got here in three days.

It seems the OP has not looked very far! 6550's are available, and in stock at many places.

I can't reccomend VivaTubes highly enough. I ordered a matched set of 4 6H30Pi and they arrived at my door in just 5 days, and I'm in the UK! 6550's are available almost everywhere - I easily bought a pair of Sovtek 6550WA for my Ref3, although I only needed one, but singles are a little thinner on the ground and he wouldn't split a matched pair.

My supplier in the UK told me Russian tubes are rapidly going out of stock though, and they cannot get any more in the current climate, so I'd buy an extra for the future.

Upscale Audio has them in stock.

@rbschauman some places are out of stock of some times many are not. 6550s are readily available. ok eurotubes has em too. yeah. semms most of your new production tube seller have em. 

TC tubes seems to have a bunch........

The Tube store looks like they have several brands.

@rbschauman  Below is a link to VivaTubes - they appear to have 6550s from a few brands

I always buy my tubes from Brent Jessee - you might want to check with him....

Yes, there is supposedly a world wide tube shortage.  Prices are up a wee bit.  Russia has made lots of tubes for years.  They are having import/export problems to most other countries, just about everywhere these days.  I have bought from The Tube Depot in Memphis and Decware on several occasions and if they say they have in stock, you see the following week.  They ship same day or next.  You have got to ask, "are they in stock"?  I believe Upscale Audio is another source.  Don't know where you placed the order but there are lots of other sources.  A friend of mine used to order his tubes directly from Audio Research and that could some times take a while.  I would keep the order in with where you have it placed, unless they are talking years to get.  You can't have too many tubes.  Good luck.
