Maybe they're not as readily available anymore. A search for Tung Sol 12SN7 Black Glass should've yielded some results.
Perhaps you could also try looking for the GEC/Osram B36 tubes (12.6 V equivalent of the super expensive and well regarded B65).
Btw, congrats on your LG! Looks like you've had a taste of the Carbon and moved up to the Glass. How does the Glass compare to the Carbon. How well does it drive the HE-6 and your other cans?
I recently sprung on a LAu at a great price, and I'm blown away by how great it sounds. It's the first taste of Cavalli for me and has left a very positive impression.
Thanks for the recommendation. Will look for those but initial searches dont yield anything.
Regarding the glass, the biggest improvement I had was the soundstage and details. It all depends on tubes too. I only have stock and RCA 5692 tubes yet, and Im waiting to receive a few pairs. This also confirms that the LC is no slouch and punches above its price. I also use the LG as preamp into my A21 power amp to HE6, which has shown good improvement over the Parasound preamp I have.
Im still gutted that I passed up on a very good Liquid Gold deal a little while ago. One of those deals that you always feel you should have jumped on. Ive only heard good things about it and wish to hear it some day.
