Music Hall MMF 5 Arm Change?

Check the arm pivot to spindle distance.  It needs to be 222 mm.  I think the older MH mmf-5 Pro-ject arm was longer than what they use these days.  It might be close to what is needed but you may still have to do some modifications to the armboard, hole size, height, etc.

And..why the desire to swap the Music Hall arm out in the first place? This is not a table specifically designed to have "the arm of your choice installed."

Best to sell your MMF5 and buy a stock P3; these arms and tables were designed and manufactured for optimal perfomance with one another. Why waste money and effort to "experiment" with disappointing results when you'll just end up devaluing the equipment at best? Frankenstein approaches such as this are rarely satisfying and are typically regret-o-genic.

Makes no sense to me.

 Well, thanks for the responses.  Sell the Music Hall I will. Since I am going to replace the arm would the P1 or P2 be suitable? Again, thanks for all your help. Cheers

Re-read the recommendation and save for the P3 a little longer. You will be glad you did. Have you already bought the arm?

  Yup, I have the RB300 already. Ok I see that the P3 is the way to go. I will start my quest to acquire today. Will this set up have the room to work with the Expressimo, old AT lift etc? I really like the convenience of an end of record lift. Thank You.

I guess but don't know. Lifting the arm is the most exercise I get. What is the rest of your gear? Have you considered an automatic turntable? 

I have full rigs in three rooms. A Cayin in the living room, a Creek destiny in the den and a creek Evo in the bed room. I also have about ten TT's of various quality and state of repair. For now, an Ar ES-1 bought new by me in '76?, tricked out a little bit with new arm, Merrill acrylic-lead platter, heavier springs, new motor, little AT lift etc. Thorens 318 in the den for convince. A Music Hall MMF 5 in the bedroom. All are subject to swap out with others in storage in the loft. Speakers, many, all in a state of flux as well. Equipment up there some as far back to late 70's. Some really good gear working as they should or in various state of repair just sitting there idle.. A bit off topic but does anyone know of a successful rehab center for a sad, possibly terminal audio collector in desperate need of help!!?? I know that I sound like a rank neophyte when I ask these questions but trying to be as informed so I can be. Sorry to drone on so.

Try this rehab: Focus on one excellent rig. Get rid of it all and use the funds to get a refurbished Garrard 401/301 or Lenco L75 in a good plinth, a good tube phono/pre like a Croft Micro etc. You know the drill but haven't made the leap. ;-)

  That is a bit too stringent for me. I'm not looking to get rid of the rigs that I have. Idle gear in the loft should go and not to keep acquiring.  There is no TV in the living room nor the bedroom. I have a 22"monitor in my tiny den and a 14" tv in the kitchen. So music is the thing with me. I do have a Bottle Head phono pre though.
