Dynaco FM-5 Tuner. Useful "Mods" for the unit??


I recently bought a Dynaco FM-5 from ebay. It was advertised as having been "hotrodded" by Rich Modifferi--- the mod was a PLL board and Dolby deemhpasis. I bought the unit to see if I could get a station which is 125 miles from my apartment house.I hooked the tuner up to a Fanfare SG-1 and it did receive the station clearly, but there is still some noise and flutter. Overall, the sound is tinny and harsh even on local stations, but also seems to possess more "depth" than the tube tuner of the McIntosh receiver 1700, I also use. By the way, the Mac could not receive this distant station at all. So whatever Mr. Modifferi did to this piece, he increased its selectivity. So, does any one know if this piece can be further "moded" to improve selectivty and smooth out the overall sound?? Or, is it not worth it. I don't want to spend alot of money either. Help!!. I know there are many knowlegable Dynaco fans on the 'GON. I don't just want to put this piece in my closet as wasted money. Thank you, SJ

The key to any receiver begins with the quality of the antenna System you use. To a degree, the higher the antenna and the more elements the antenna has the better the chances of dragging in that weak station. You can add an antenna amplifier to the circuit which boost the signal.However, at the same time its accompromise because you also increase the noise level. Another key is good lead in wire. You probably won't find it locally. Most people don't think. They just run to their nearest do I Yourself shop( and they don't have the good stuff). Order on line from Wireman or another reputable place. If you loose all the signal in the wire you haven't gained anything. Its hard to find a manufacture of antennas that will give you any real gain figures on their antennas. Channel Master and Winegard are amoung the few that will and they make antennas that last.
Probably the very best of FM receivers out there would be a debate, but the one I prefer is the McIntosh MR-78. It has the extra stages necessary to do the job, but not for the money you want to spend.
What you want todo. Evaluate how much you can spend. Get the facts:
THEN buy
First - By the best antenna you can afford.
Second- Good Lead in wire
Third - Try a antenna line amp
Fourth- If the FM 5 doesn't cut it, check to see if it was and still is tuned up properly. Perhaps a new receiver
Many years ago I installed a Dynaco FM-5 Modification Kit from Universal Audio P.O. Box 712 Providence RI 02901. The kit was made to correct the thin bass. It used better coupling caps and tighter tolerance components to lower hum and distortion and flatten frequency response.

I doubt if they are still there,but it does not hurt to try.

I still have the installation instructions if you would like a copy.
Anyone know of a link that would explain how to "restring" an FM5 tuner.
First time here so sorry if I'm intruding on a thread.
Thanks,

Sorry, I'm fresh and new owner of my Dynaco FM5. I'm looking every help to upgrade my tuner. Many years ago was a post from @denniscameradoc8f6c
And he want to share an instruction with Universa Audio mod. 
Maybe somebody knows where to find this or how to change FM modulator wit PLL. 
Much appreciated for any advice.
