ZP3 front tube
05/12/20 at 23:31:46
 
I just had my Raytheon 12AX7 in the front spot go bad.  I like these tubes but I'm not seeing anything reasonable on ebay right now.  Can anyone recommend tubes they like for this spot?  I'm not into high dollar exotic.  $20-ish would be great.

Adam, I read good reviews on these about a year ago, and have been very happy with them.

GE JG-5751 triple mica black plates.

This is an example of what they can be found for on eBay:

I just found this review of 12AX7 tubes. †The Raytheon and GE are both highly regarded.

Cool.  Below is the long article I read about a year ago that got me to try the GEís. Also tried the RCA clear top 12AU7 because of this article. Use the table of contents at the top - 12AX7 Part 3 for summary, and the very first part that evaluates the 12AU7. I use the black plate 5751ís in the first 2 spots, and the RCA clear top / side getter for the third.

Ya'll don't forget too, to try an RCA clear top 12AU7 in the third spot. Another affordable tube that sounds really good.

Thanks Geno Iíll look for the 12AU7. It seems the JG-5751ís are creeping up in price since you guys got yours.

OK Geno, another JG-5751 is on the way as well as the clear top 12AU7. Iíve got so many 12AU7ís but not that one. There cheap so I guess one more wonít hurt.
