"Hot Mod" Dynaco FM-3

Just recently begun another FM-3 restoration, this makes my third one, and I thought
I would do something different, because of the threat of oxidation,and rust to
The chassis, I would either powdercoat, or paint the chassis, I chose painting
This time, because of cost , although I have checked into some powder coating
Systems for DIY. It might be something to look into later. I chose hammered copper
For my color. Turning out nice so far. I will post more as the project progresses.
I will be designing a new front panel as well.[img][/img]

Hi Den:
Looks like you are doing a fine job on that FM-3. I did 5 tuners last year including one with a new one piece motherboard. I ended up with a lot of parts and spares as I bought a couple to get parts in good shape. The point is I have a lot of stuff lying around. If you need anything for your project I probably have it. I also have a friend who will be coming down for a holiday and returning on the 7th of Feb. so I could make you a pkg. of whatever you need and send it along. The only thing I don't have spares of is trannies.

Sounds great,I think there are a few items I need. One part in particular is a Stereocator,I have two more left,but one is for the FM-1. Can't think of anything else right now,maybe more sockets. BTW Thanks for the comments. I have to tell you baddog,these tuners are just plain fun to work on,I had a few problems when I first started,alignment procedures mostly,but once I got that down,it takes me no time to align one.

If you have an EMM801 tube (the FM-3 indicator tube), guard it with your life! My only spare was sent to me by none other than the late Bob Tucker
at Dynaco...who included a note saying it was the last one they had.

The EMM801 was first used in stereo tape recorders as a two-channel level indicator.

On an FM-3 that I rebuilt a few years ago, I substituted the EM84 tube used in the FM-1 (it is much more common) and put together a driver for an
LED, to use as a stereo indicator.

Dynaco's instructions for the EM84 substitution (and how to align your multiplex decoder using a meter instead of the stereo section of the EMM801 tube)::

Replacing EMM801 wiht EM84

Hi Den:
Unfortunately I omitted the stereocator (EMM801)as another part I don't have spares of, sorry. I can send you anything else I have Free Of Charge (of course you pay the shipping). I have to move and need to get rid of a lot of stuff I won't need and I would like to give it a home with someone who will use the stuff.
Check out my photobucket page for a few pics of the tuners I did. I incorporated a switch setup in mine that allows easier aligning when you get to the stereo part.
I can send you the schematic if you are interested. I got it from Chauncey Epperson who IMHO is the FM-3 guru. He may have a EMM801 if you are unable to find one elsewhere. Keep the photos coming of your build.
cheers

I'm sorry I should have been more specific,I need the plastic inserts used for the EMM801,I have plenty of 801's. The schematic would be nice too. I'll PM you with the imformation you need,Thanks Again.
