Where do you guys buy tubes?

Just got off the phone with Kalvin at ARC regarding KT120 or 6550.  I will do 6550 because transformer will run hotter with KT120 and will shorten life of transformers.  So I only need one matched pair of 6550.

If you are looking for a set of matched KT-88s, you can get some very decent JJs from https://www.cedist.com/ (formerly Antique Radio Supply) in Arizona. They make distinctly better KT-88s than the usual Russian or Chinese fare.

Andy Bowman is a good source for NOS types. TC Tubes is a good vendor too. We've done very well by Upscale Audio.

Upscale Audio, Jim McShane, Andy at Vintage Tubes has always been my go to suppliers.

Thank you very much everyone for your input.  I am sure this info will not only benefit me but will be benefit to many other that looking for a place to purchase their tubes in the future. 

Regards,

Ebay for the odd ducks (6C33C-B and 6350) that I then send to tctubes for testing.
