If anything, message 'remyrad' on the Yahoo groups. She was the lead QC when the machines were built. I doubt she has a manual, but I believe any Q's you have can be answered.

FREE: 2x SDC custom copper mic bodies for DIY project

Hey all, I got these from a DIY forum member, and I'm simply really, really cleaning house for some projects that I can't partake in due to a move. I had these made for me for the idea of doing a tube SDC or electret mic pair. Pics here: http://austin.craigslist.org/wan/5121921468.html If you had a ...

He says it in the next paragraph: "In the absence of replay head losses, this gives a flat frequency response (especially at 30ips)... at lower speeds, gap and thickness losses are significant and further eq with a high frequency boost (f) is needed..." This is really true! When I run 30ips, I find ...

Hey! That's a good re-type! That's it! I hunted down where the 'NAB and IEC' curves you talk about came from. Those are the flux curves of what a calibration tape looks like without the repro EQ HF boost. Without that context, it looks a bit confusing. Here's a little more thought (and, this is just...

Hey everyone - The topic of tape's recording equalization, and what is happening, is the single biggest misunderstood topic when it comes to tape machines. Ok, here's the summary: - Due to the physical nature of the tape recording process, there is a short wavelength (ie, high frequency) loss 'built...

you're there. that's the way to calculate the output impedance of the tube in a standard CF. the impedance bridging rule-o-thumb is for the output impedance to do into ('should be driving into) an input impedance 10x it's size. it doesn't need to be. this is something you can voice to taste. driving...

i'd think you'd be better off doing a dremel-mod and just being able to move the playback head ala an echoplex... re-tach-ing a capstan will help, but it will most likely show it's limitations of what the capstan will take (or give) within boundaries (or being unreliable/burning out). a slidey playb...
