Got plenty of those! My other amp is a Project Sunrise, one of the most versatile tube-rollers out there. I also have two matched pairs of 6V6s to try (Tung-Sol and Sylvania).
Nice! Coke bottle Sylvania's or the straight ones? And those Tung-Sol: vintage or reissues?
I've been running a matched pair of reissues but haven't been impressed with them. Too much roll off at the highs for my taste, the sound was a bit dark because of it. This was with a Philips 6201 gold pin as pre.
Currently I'm hooked on the 6201 gold pin together with a set of vintage Visseaux. It's a very resolving, but pleasant sound. Good soundstage, tight (but not exaggerated) bass and great seperation. A perfect balance that matches a wide range of music.
If anyone wants to dive a little deeper into the world of 6V6 and 12ax7 tubes, here are some great specials with reviews and background:

Instead of 12ax7 it's also possible to use different types like 12at7, 12au7 and european equivalents (ecc83, ecc82, ecc81). I've had great results with 12at7/ecc81 tubes which are generally cheaper too.
The same goes for 6V6. It should be possible to use 6F6, 6Y6 and 6L6 with the APPJ (warning: on your own risk, this hasn't been tested). The advantage is that some of these are in lower demand and thus a lot cheaper.
I've asked APPJ about the use of 6y6 tubes and they comfirmed:
Thank you for your email once again.
Please don't worry,i have asked our technicians again,they told me that this is not a problem,you can use 6y6 tubes replace the 6p6p tubes.Thanks.
Note that the 6Y6 draw a lot more current than 6V6, but apparantly the APPJ is build to spec for them as well.
