You have some of the most lust worthy tubes/valves I've seen to date.

Do you have any Mullard MC1 long plates?

Finally got around to taking a picture of the one tube I have in my system (Peachtree Audio Nova): A 6DJ8 made at General Electric’s Owensboro (Kentucky) plant during the 43rd week of 1962 (thankfully, I have a few spares).

This is what the tube looks like while playing Kind Of Blue:

Hi Mike,

I reviewed the Peachtree iNova for Stereotimes and that is not the factory tube. How do you like the GE? Have you tried other vintage 6DJ8s with the Nova?

Cheers,
Paul

Hi,Paul,personally I don't like these black plate Mullard as they sounds a bit bright and thin compare to the 1600 date code.Another black plate valve which I really like is the Brimar 12ax7 which I am using it on my amplify, so no regret even you never heard them before.

Hi Paul,

I swapped this in after the original piece of Sovtek junk died in less than a year.

I love the GE. It does a great job cutting the sonic sludge on CDs and opens things up a bit. With DVD-A, the biggest change tends to be on soundstage (better depth and definition) and noise floor (lowering/eliminating). On SACD, it tends to give a little more body, overall.

After I had the tube in for a while, I decided to play around with using attenuators (Rothwell). Another huge difference after I did that. To get the most out of the tube, I've got to get the volume knob in the position/range of 10 o' clock to 2 o' clock.

I haven't gotten into any serious tube rolling with this unit. I planned to, but I've been so happy with this GE, I haven't felt the need. I did drop in a gold-pinned Amperex 6922 from the early 70s for comparison. The results were not as dramatic, and not quiet as warm (meaning, analog-sounding).

Be Well,

Mike
