Tube rolling in ARC preamps?

[TLi]

I have just put the EH6H30 in my reference 10. The EH sounds brighter and more solid compared with the original Sovtek. It would be just the effect of new tubes. For the relatively small cost for a set of EH tubes, all reference preamp users should give it a try.

I am not going back to Sovtek.

Whoa. Does one use 1 under each foot or do you use 3?

I changed the original sovtek with 6h30dr of 1972, far better than sovtek. I changed tthe 6550we for 6550c , and they were more. But the best result i got is a 6550 tung sol black plate of 1958, a little better than the grrey plate of 1961. Tung Sol explore music as no other one, for my taste.
My conclusion is that 6550 ts and 6h30dr lead ref5se to another world and deeper into music.

Those are the tubes I am using in my Ref 5 SE and Ref 2 Phono SE. It is the best combination I have tried.

I am going to consider isolation, but some of the solutions are very expensive.

Three is fine but I found 4 is even better.

What did you pay for the 6 h30dr's and where did you get them?

What is a good/reputable source for the 6H30-DRs and the 1958 6550 Tungsol Balck Plates? If I ask that the measurements on the 6550s be provided as well, what should I be looking for gents? Also, what are we talking about roughly speaking for cost/tube for these two types? te 6H30-DRs that I have seen advertised seem to be in th e$200 range which is quite pricey? What about the Tungsol 6550?

Thx

I got them from this seller: tanerunlusoy on eBay

They vary in price based on the vintage. He is very good to deal with.
