12AX7 tube alternatives for Jolida JD-100

I tried the Sylvania 5751 triple mica black plate and loved the richness, but not the heavy bottom end. Went back to the Svetlana 12ax7's until someone posted something about the Chinese Full Music 12ax7's. I bought a pair for around 70 dollars, and found they were very comparable to the Sylvanias, but balanced across the board in my system. Sold the Sylvanias, love the Full Music!

I'd also consider ECC803S

Rooski-

I googled 12BH7s and found interesting info about them. They have equal gain (mu) to 12AX7 but draw twice plate current and give off a lot of heat.

People who have used them in Jolida amps say they increase the soundstage and are more dynamic.

Also, Cary six-pac owners use them because they increase watt output and decrease distortion.

Like you I don't think I would use them because I'm not sure how the circuitry would respond to extra heat current.

Also because of their size they are microphonic, but that can be tamed by using a Herbie's Halo.

Wharfy,

I,m assuming you meant to type "12BZ7", and yeah, I've read similar comments.

I just recently found out about the TJ Full Music 12AX7's, which sound promising, but are pricey.

Yes, 12BZ7, not to be confused with the annoying B&H commercials I keep hearing constantly.

I also heard about the TJ's. Extended without harshness is a phrase I have read. Does this mean "without grain and glare?"

At $110/pr plus shipping I also find them pricey.
