ARC Ref 3: Tung-Sol 6550 in power supply?

I have sourced a new production Tungsol 6550 from The Tube Store in Hamilton (Ontario); I intend to use it in the power supply of my ARC Ref 3. Has anyone had any experience with the Tung-Sol TS6550 in the Ref 3? Have you compared it with the original Winged "C" SED 6550C shipped by ARC with this
line stage? Preferences? Reasons?

I thought I had read somewhere that the 6H30 tubes were rated for 10,000 hours? I understand that this is probably a pipe dream but 1800 hours is a long way off 10,000.

I've got over 600 hours on my LS-26 so maybe I need to plan on an earlier swap out than first anticipated???

BTW, I have been to the Tube Store and they are great guys.
