Very happy with GGL AU's and AT's.  Tried a NOS Amperex in the pre-amp socket, and very little difference between it and the GGL.

I like JJ’s. Their ECC83s sound great and don’t cost an arm and a leg.

In my Jolida 502P (a GREAT amp sold recently as I switched to a single ended thing) I used GL 12AX7s and they were great…for 12AT7s I used NOS Mullard 6201s or 4024s which I really liked…and they flash on start up which is a bonus and a crowd pleaser.

I just received my amp today. It came from the factory with TungSol 12AX7'S & 12AT7'S for line and Electro Harmonics for output. It's been outside for quite a while. I'm not going to plug it in until tomorrow. Can't wait to listen to it

I had tried the Tung-Sol and found them to be a little sterile in my Unison amp.
In place I am using the RFT, though a little darker I like the richer tone.
