I am going to be rebuilding my old fuzz. I have an original Dallas Arbiter Fuzz Face that has seen better days. It is basically dead, but I have just ordered all new parts for it from Small Bear Electronics and I am going to try to bring it back to life (I can hear the thunder in the background and the sound of the jacobs ladders as eegore is running around the lab.) I am going to try a small modification that I found here
http://www.geofex.com/Article_Folders/fuzzface/fffram.htm that is from Mike Fuller (it looks to be a simplified version of his '69 pedal).
I will let you know how it comes out when it is finished.
For some stupid reason a long time ago, I put it in a small box and I have lost the original round case for it. Those old round boxes are awkward but it would have been quite the conversation piece to have it in the old grey round Dallas Arbiter box. Oh well, I will be putting it in to a new white powder coated box that I purchased from Small Bear that will fit much better in my pedalboard.
