Tube Roll for McIntosh C2300 PreAmp

I just rolled a pair of Gold Lion Super Cryo and already noticed the diff. I also got a pair of 1950 Telefunken that I will try after 100 hours with the GL. What difference could I expect from the Tele.?

I hears JJ Tesla was also a good choice for tube. Anyone have experience with JJ Tesla?

Sorry, didn't see the post.

Teles here!

I bought 12ax7 Telefunken tubes from Brent Jesse Recording Supply Illinois and am extremely happy with the results! Best $200 bucks ever spent!

Manoterror - Wher can I find the tubes you are referring to?

FWIW, Mullard 12AX7 reissues made a huge improvement in my C220. McIntosh has told me that, other than the phono section and a few features, the C220 and C2300 are the same.

Have no experience but would be curious if anyone had success using 5751s. Just a thought. There are a few really good current 12AX7s. I like current production Tung Sols but not better than my Sylvania triple Mica Blackplates from the 50s. I just don't know how good a 5751 would sound in that circuit.

Telefunken ribbed plates

Telefunken are the bomb!

I use super-cryoed Mullards from cryoset. They are not expensive, and have a super black background...while smooth as silk. Try em out.

Mullard and Svetlana are other options.
