I wasn't able to do the test last weekend, but I'm gonna get to it tomorrow. Also, I picked up a Groove Tubes 12AX7 to add to the test.

I will probably switch the stock speakers for the WGS Veteran 30's after I do the tube shootout. I will also post a comparison of the speakers.

Tomorrow I'm replacing the 70-80 with a Classic Lead speaker, and I'm considering making it a (half) open back instead of closed.
I posted this in some other thread as well.

I still like the TungSol's best, most musical sounding, no noise, excellent harmonics, smooth gain. The stock TAD EL's are still in, because I think they actually sound quite good, they just add to the total sound volume and do not colour the sound too much. I installed the Classic Lead speaker which has considerably more bottom end than the 70-80 and overall is a very balanced speaker frequency-spectrum wise. No mid-push or mid-dip and it doesn't break up early which I like a lot.
In a closed back you get an instant Marshall sound. But I made a custom backplate that's 2/3 open. Sounds way more dynamic this way not so tight and direct, like the Fender combo's do. Probably not suitable for the (really) higain players but for me (and my bandmates) this sounds best. Due to the speaker and open back I had to change the EQ a bit, bass 12hr, mid 13hr, treble 14hr, ISF 9-10hr, reverb 12hr.
Yesterday I finished my selfmade analog pedalboard, and invested in the (expensive ) Klotz 110 cables with gold jacks, really blocks out all interference signals I had before on stage due to lights etc. I now have a killer setup that's fulfills my allround guitar sound needs.

While there is nothing wrong with Groove Tubes, it seems that the consensus is that Tung-sol and JJ tubes are better(and less expensive). I would go with these...

If you decide to change your 12AU7, the Electro-Harmonix is nice.

Here is a site that has some reviews of the most popular 12AX7 tubes. Groove Tubes weren't in the test, but they are known to be "ok" but not great.

Hey OP! Can you at least give us some written feedback? I know posting clips can be a pain so how about a quick written review?

Well, I tried to do the shootout this past weekend using the amp's speaker emulated output. For clean tones it is fine, but for OD it is absolutely horrid. Very fuzzy and thin.

I think that the only way to do it properly would be to record a couple of clips directly into my audio interface, then re-amp it by sending it to the HT-60 and recording the output with an SM57. This seems to be the only time effective and uniform method.

In the meantime, check out the 12AX7 review at TheTubeStore.com. Their reviews are probably better than anything I'll manage.
