Got asked some questions on tubes, here are the answers: PSVANE WE275 391.00 is bloomy. I have a pair when I am in the mood. Sort of a cross between 300B and 2A3. PSVANE 2a3B 145.00 better quality version of the Shuguang 2a3B. Worth is so you don't have to waste time sanding off the solder gunk on the Shuguang pins. Shuguang 2a3B 125.00 decent tube, great price, possible solder gunk on pins may require effort to sand off. PSVANE 2a3TII Really smooth and gentle on the ears - baby butt smooth. I'll get back with more comparisons time permitting. Don't want to say anything unless I can get a one to one comparison with know tubes and can triangulate. I'm still a fan of the sound of American vintage tubes.
