12AX7 tube alternatives for Jolida JD-100


After using Mullard, Telefunken and Amperex 12AX7s, I've substituted 5751 command series blackplate, 12AU7WA, GE5814 and 6414 Raytheon blackplate, a 12AT7 variant.

I thought the 5751 was nice with lower gain and warmth, but still had grain that smears sound.

The AU7 and its variant was too sterile.

I'm impressed with the 6414. Focused sound, holographic, good bottom to top presentation without being too edgy.

Anyone else tried something like this?

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.
Look on ebay for the Full Music 12ax7's. I got mine there for $69.99 plus $5 for registered mail shipping from Hong Kong. Gold pin new in box.

For $70 and postage I took the plunge. I'll start looking in the mail next week. It's nice getting something other than bills and junk mail.
I think you'll like these. The Svetlanas I was using lacked good bottom end, so I put down some serious money for the Sylvanias, which really improved pretty much everything. But they brought along some serious bottom end, a little too much for my liking, so I went back to the Svetlanas. I read a post here on A'gon about the TJ Full Musics, and did what you did. I feel they are just as good as the Sylvanias, if not better. They are balanced from top to bottom and sound great! If I remember correctly, they didn't take a real long time to break in. Keep us posted.
