Upscale sells tubes of the highest quality. My go to sellers are Brent Jessee and Andy at Vintage Tube Services. They sell high grade tubes and offer a return policy, which is great for a tube roller such as myself.

Good stuff!

Well done, the Philips are very close to top of the hill!
Good that you will first do the PSU/rectifier before you do more rolling, especially because rolling rectifiers is another adventure! 
I wouldn't worry about Siemens, I don't believe they can beat what you have in an ARC phonostage. Maybe if we were talking DACs or a Preamp that handles a digital source. 
Yes the Teles are better than Philips in an ARC phono but also sound slightly cooler which you might not like.

Thanks. Yes you nailed it. Before I do anything else I will be doing the power tube upgrade. Obviously you know what that entails. For those who don’t ARC used 3 power tubes in the PH7 (prob other models as well). What they found out is that the 3 tubes wear unevenly which causes/could cause degradation in SQ. To resolve this they came up with an upgrade to replace the 3 tubes with a single rectifier tube that is supposed to A. Resolve that problem B improves SQ overall. So I’m really looking forward to that mod. I’m on a waiting list about 7 deep because ARC was only doing warranty work during covid but they are now taking in some upgrades and service work. It must be quite involved because they would not give me permission to have my local tube gear guy get the plans/schematics and the upgrade kit for this mod. So I’m waiting. It’s all good tho. Sometimes patience pays off.
