That is sort of where I started. Got info from AVA on the kit and when I was going to order it to do my PAS3X, Frank had a sale. Got the 4i, assembled, for a little more that I was planning to spend. And it was tons better than the Dyna. And after a transformer change and Frank's most recent op-amp upgrade, it still amazes me how great it sounds. Still got the Dyna. Get it out about once a year, fight hum from the jack panel, and listen a little. I built it in the late 70's and it still works. And sometimes I think "Maybe I ought to order that kit...." But I get over it.
