Prima luna dialogue 2 tube rolling

The NOS ECC83 Mullards, which made before 1970's, during 50's are the best, imo. They are not dull or to warm or what ever, they are just great. I rolled lots of ECC82, ECC83 in my previous Primaluna Prologue Two and ended up with NOS GEC KT88 + ECC83 Mullards + CV4003 Mullards. Even in my CDP still sit 2x ECC82 Mullards. I also highly recommend NOS E83CC TESLA or ECC803S at least, but dont mix up them with general ECC83 or fakes, cos they are nothing alike, here you can read all info you need http://www.jacmusic.com/nos/ECC83-part-numbering1.html

Further, I tried all kinds of TUNG SOLS, TELES, BRIMARS, TUNGSRAMS, PHILIPS, SYLVANIAS, but still prefer truly NOS Mullards. You can make some nice combination, where not only the Mullards are in, but say TUNGS SOLS BLACK GLASS + Mullards, but better would be BRIMARS and MULLARDS, but than again, made during 50's or earlier 60's

One last, but sure not least, is Mullard CV491=ECC82, but than again, sorry for mentioning this over and over again, but you need the one from 50's, this one

I know that it may sound bit to Mullard, but thats my conclusion that I have based on years of tubes rolling, where folks see them as warm only, which is not the whole true, imo.

About EL34. I only tried NOS TESLA's and found them a very good alternative to NOS GEC KT88.

Good luck and hoping your wallet can handle it:)

Thanks for the suggestions so far.

@Maxmad Thanks, probably I will end with NOS tubes but at the moment my wallet still needs a bit recovery due to a happening involving tubes that took place about 2 months ago;)

What about the, more affordable current production pre and powertubes, which brands and types tend to add a bit of warmth?

Is it wiser to change the preamp tubes for a bit more warmth or change a powertube instead so you can use more transparent sounding preamp tubes?

You can go for GENALEX KT88, seems to be a nice modern production tubes. Alos, C logo of Svetlana's EL34 are one to take a look at.

Yes, pre-amp tubes are very important and you can better invest in some nice NOS, not very expensive, but still a good one and thats BRIMAR's http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=180558460740&ssPageName=STRK:MEWAX:IT of http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=180560154874&ssPageName=STRK:MEWAX:IT

or RCA long black plates http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160490277846&ssPageName=STRK:MEWAX:IT

Make sure that the plates are long and black, before buying, its very easy to see what ever its grey or black.

Check Ebay UK more often, where lots of interesting valves comes up, but be carefull about their test results, cos lots of shity stuf are on Ebay, where folks just dont tell the true, so, your own tester is a must if you in the tube world.

Good luck.

I found this web a very good for the info

Maxmad, Rodman, for those of us who cannot afford true NOS tubes, what would you guys consider the best subs? I have a Dialogue 2 powering a pair of Klipsch Cornwalls.
