Just this past summer I dove head first into Mac tube gear with the purchase of my first system........ an MC240, MCD7007, and my tuner/preamp, an MX110. Initially was not thrilled with the MX110, tuner portion. I had some station drift and could not seem to get my tuning eye to get much closure, i.e. not pulling in the stations very well. I sent her off to the TerryMeister and, well, you folks who have ever had Mr. DeWick put his hand on your unit, wait, that didn't sound right, upgrade one of your Macs, knows just how talented he is. My 110 will pull in stations out of Minneapolis, and I am 40 miles southeast of Chicago. So we are talking about 125 miles. Find myself listening to a lot of Chicago stations as well as some from the burbs, since pulling in a station some 50 or more miles away is not a problem. Of course after several weeks of wrangling, I finally got my Brother to put up the dipole antenna on the roof. Boy, that sure helped! Before retiring the Terry-ized 110 for safekeeping, I bought another that had been aligned, etc. by a non-Terry individual. Needless to say, no where near the performance but adequate. Found myself buying another MC240 which I eventually sold, and more recently purchased (2) MR71's which neither have been powered up. I've also added a C22 which is in the process of a power supply upgrade, and its intented use is with my MC240, and MR71 which will be upgraded and aligned. Then, I think I am done. Yeah, right! This weekend I am planning a roadtrip to pick up a complete outfit, MC240, C22, and another MR71. Why, I haven't a clue. I'm one sick puppy! Has anyone with MOCD (Mac Obsessive Compulsive Disorder) ever gone through an intervention?
