Shuttlemax tube subs
I had my ShuttleMAX 12.0 opened up to troubleshoot an intermittent output problem (loose connector) and while I was in there, I decided to try a few different 12AX7s in the tube side.
I have a pretty good collection of NOS Amperex, Brimar, Phillips, Telefunken, GE, etc, etc preamp tubes.
What I ended up liking the best was a new production JJ ECC83S. Really balanced, nice detail, low noise, real musical. A nice upgrade over the stock Ruby chinese. I didn't expect a tube swap to make this much difference, because they usually don't in clean applications. I bought this amp used, so no telling how many hours were on the orig tube, but compared to a fresh tube, it sounded very dull.
Anyway, for me, it was $11.65 well spent. Just saying.
