Yup. I just got a Kalamazoo 2 back from Gregg. He had made some repairs/modifications. WOW, What a difference, it is like a new amp. I have not tried the line out, but I have no doubts about it. The speaker phase switch is an interesting feature as well. Greg's work is top grade! Too bad shipping (both ways for me) is such a big cost. Thanks Greg!.
