Tube Tuner: Eico HF92A and Mcintosh MR 65

I have been using Fanfare FT1A for sometimes (with Rogue 99 and 88) and enjoy the CD quality of classical station (and other stations) in Chicago. I have always wanted Mcintosh MR71 (or 67) but the problems are either the price is not right or there are too many "sold as is" MR on Ebay. Somehow, I got an Eico HF92A last week and was surprised to hear its warm and sensitivity, I mean comparing it with my Fanfare FT1A (in some stations, not all), the old Eico HF92A is not that far off. But I think HF92A is mono? So my first question is anyone knows about converting HF92A to stereo? OR did I miss something? The second question is: why the left speaker is producing high pitch sound and the right speaking is producing midrange to bass (when HF92A is played)?
My third thing is regarding MR65. I am about to get this MR65 but like to know if it is comparable SONICALLY to MR67.
I think I will sell my Fanfare soon and get into a tube tuner. Thanks in advance to all your help.
