12AX7 replacement


It’s time to replace my tubes in my preamp. I’m looking for some suggestions as to specific brand performance and or where to purchase. There are a total of 8 all 12AX7. I believe 3 are for phono and the rest are for preamp and tone control circuits. Thanks in advance for your opinions.

Brent Jessee at Brent Jessee Recording will give you good recommendations and has a large stock and will offer an optional warranty on your tubes (not a bad idea with NOS tubes).
I just tried the new JJ Tesla Frame Grid E83CC.  I found them wonderful sounding.  They are only ~$22.00 each.  They have gotten some very excellent reviews.

There are many choices for you out there.  Depends on how much you want to spend.

Good Luck!
