I've just had a look at my STA15 III. The EF86s are Siemens and the ECF82s are Telefunken. I do have a complete set of Mullard valves for the amp as back up, but I came across the alternatives cheaply and just popped them in.
Can't say I've done any serious tube rolling - but as others have said, the Radfords sound great regardless of valve manufacturer; though based on the experience of the guys at Chelmer Valve Company (whose premises are not far from me), Chinese valves need to be carefully screened for quality, so I would tend to avoid them.

I'm Ian.
I certainly agree with the comment regarding signal valves having more influence on sound. I can't recommend these on the basis of comparison with other valves as I haven't 'rolled', having bought them on the basis of NOS at what I considered to be a reasonable cost, but all sounds mighty fine to me.....

Anyway, just for your interest ;-)
Interesting thread! I've just realised I'm in exactly the same position, I'm rolling EL34's in my Radford. I dug out my old STA25 and had a good listen. I couldn't remember what I'd plumbed in earlier but had a blind listening test. Several hours later and I'm very happy with my results, turns out they were Electroharmonix . I've been looking into vintage American valves and may even try some of the JJ's considering that they are an exact copy of the old Mullards. I do have some old Mullard 34's but I'm not sure how strong or matched they may be. JJ's have a good reputation, I liked the JJECC83's when I tried them in my Radford Pre, but ultimately went onto a batch of NOS Mullard ECC83 yellow labels (even though the JJ's were supposed to be an exact copy of the Mullards ). Oh, decisions, decisions!
