Hello All:
Since the discussion on the Emission Labs 5U4G tubes have been getting some attention here, I've been getting quite a few emails regarding their availability. The fact is the tubes have been in short supply

, and have been on back order. I received one pair of 5U4G tubes today, with the expected arrival of some limited quantities around Mid-December. Please feel free to email me with your email address so that I may contact you when they arrive. Thank you all for your interest!
Best,
George Lenz
