Tube Dealer Recommendation

Hi There,

I am hoping to re-tube my Cary SLI-80 amplifier with NOS tubes. Specifically looking to change out the 6922 and 6SN&. There seems to be quite a few tube dealers out there. Anyone have recommendations for well regarded tube dealers whose integrity, tube knowledge and tube selection skills you trust? If you prefer, feel free to private message me.

Thanks for your help.
