If you guys ever get to listen to a good #1,2,or 3 copy tape on a good RTR you will be in utter awe... I have had the opportunity a few times one of which, Polk member Luther ie @Wardsweb
When I hunt what I consider true DSD recordings, I first look for those taken from master RTR.2-channel: Modwright KWI-200 Integrated, Dynaudio C1-II Signatures

This is the earliest advertisement I've seen for Ampex found in Audio Engineer 1948:

Hi Folks: Hope all of you are well. The same friend who gave me my first Ampex 350 gave me a second one (!) and I want to do the same restoration using GAS PCBs. The problem is that Recording With GAS seems to be MIA -- no web site and no response to messages via FB or Gearspace going on two years. If anyone has a set of PCBs (power, record, and repro) that they don't need, please send a message! Thanks, Steve

nice find. -
I'm rebuilding half a dozen Ampex tape recorders, refitting a recording studio. I'm having huge issues with the female spade connectors of the 351 boards; it's actually a major problem. They are loose, corroded and break at the slightest pressure. I know they are similar to a Faston, but they are female and slide over the edge paths. Anyone working on one of these will see this problem. Does anybody make these little gems anymore or is this a complete hardwire job I'm facing? Thanks for any help!
-
The first step I use is to clean the complete wiring harness in an ultrasonic cleaner with hot water and Simple Green. Then I very carefully burnish the connectors with a Dremel tool using a fine brass wire wheel attachment. I have done the same approach on hundreds of similar Revox harnesses, so I am very careful of breaking wires. I have collected Ampex and Revox wiring harnesses, over the years, so I can replace anything that does get broken.
-
Was able to do some slight bending and crimping with 4.8mm fastons and they'll work great in a pinch. The orginals were incredibly thin and I'll probably hardwire the connections in the future. By the way, I've rebuilt just about everything on the first of these units, including the balanced capstan -bushing bearing motor with low clearance bearings. What a great design; quiet and smooth. By the time I get done with about 10 of these, I should know all the tricks.

Here's a photo of Pink Floyd in a Decca studio with an Ampex MR70 in the background. The MR70 is arguably the finest sounding tape recorder ever made, in my semi-humble opinion. -
Great thread. I'm working on an Ampex 30750-09 version of the master electronic assembly with variable equalization (part #31172). Crucially, someone in the past modified some of the wiring coming from the variable eq., and I've been unable to find any schematics or photos of the stock set-up in order to reverse the mods. I believe what I need may be in this version of the manual, though I'm not 100 percent certain.
If anyone has any leads or other references before I pull the trigger on buying this manual (available on ebay), please let me know. Thanks!

Hello,
I would recommend sending an email to Dave Dintenfass at: www.fulltrackproductions.com he is extremely knowledgeable about anything Ampex.
Good luck with your project!
