12AX7 DRRI question

[shakerAU]

I've swapped out V2 in my DRRI with a Tung Sol reissue and noticed an improvement in tone.

Should I also swap out V4? It's a Sovtek 12ax7WC,
I have an unused Sovtek 12ax7LPS here at home, would that be an improvement?

Thanks
John

Try it and see. If you don't notice much impact, then swap your original V2 and V4 and then try the Tung Sol RI in V4 just to guage whether or not you'll hear an improvement by upgrading the tube in that socket.

Is the 12AX7LPS a better tube than the 12AX7WC?

Nothing is "better" unless you like it better;)
