Glad they're working for you! I haven't heard them with O2s yet, but they're pretty robust, from what I've heard.
By the way, I had the top off the 7tII today and noticed the tubes are 8FQ7. Probably a change made when they modified the heater/filament circuit for DC supply. Supposedly, the 8s are different in the shape of the plates, too. They're GE, and have no idea of their reputation, but, again, I love the sound of the amp.
Anyone want the set of new Raytheons (6FQ7) I bought to tube swap? I'll sell at my cost.
