7025's are supposedly notorious for being great, and then going belly-up. They are supposed to be out again in the future, but for now the plant is down.
I think similar results of the Ei 7025 could be had with a nice, measured and tested 9th gen Chinese in module V1; maybe a second one in V2 of the module, or maybe a Tung Sol 12AX7 in V2. Plus, V1 in the head/rack unit will play a HUGE role as well. No mention of what V1 was in that head. Do a Tung Sol 12AX7 or maybe even a JJ ECC803S (tested, of course) in the head V1, EL34L biased mid to hot, and then pop two 9th Gen Chinese (tested for hi gain) in the module V1 and V2. Too thin or brilliant? Swap in another Tung Sol for a Chinese (module V2 would be my first choice), or go warmer NOS in V1 in the head, then push the gain a little more, or boost in front. Too many people disregard lower gain (but warmer) V1 tubes (NOT the module V1!); sometimes it can allow the most incredible control factor thru the use of a pedal or different pickups up front. Interaction!
Pickups, speakers, cab, and volume will play some part.. and the person playing being the biggest part IMO. As an example, I have yet to find a single preamp, module, head, amp, etc that an EH will work for me in. Put one in any module, amp, etc, and all I have ot do is play one note and I know it is an EH or similar tube. Oddly, a Penta vs an unbranded (but tested!) 9th Gen Chinese is easy to pick as well. I love seeing people use gear that does not work for me. And I love finding stuff that never stuck out that is magic... for me
