I talked to Marc at Skreddy and he agreed and even was nice enough to test what I heard with his gear. There are some circuit changes with the older ones as he was revising it. There was different input cap & all carbon comp resistors. Where as newer ones use metal film resistors in much of the input & output stages. It's a trade off to keep it quieter.
Please provide a photo of inside circuit, I'll know if it's what I want, or # inside lid that I'll check with Marc (I think it's gotta be 0-200).
Thanks for any help locating one
