1/4 Track Playback Head On A Nagra IV-S ?

Recommended Posts

I have a Nagra IV-S machine which I used to transfer quite a few 2 track tapes to digital.  However, the utility of the machine as a transfer and home audio deck would be magnified a thousandfold if I were able to play 1/4 track tapes on it, of which I have A LOT, as well as 2 track. As a safe transport for old delicate tapes it has no equal.  I was thinking that maybe a 1/4 track playback head could be installed where the pilotone head is, and could be switched in and out of the playback amp. Has anyone ever heard of such a conversion?  Has anyone here ever converted a Nagra into a 1/4 track machine? Or know anyone who could do such a thing?  Has anyone here ever SEEN a 1/4 track conversion on a Nagra?  Any thoughts on the subject would be so welcome!

I'd love to learn what can be done. I have dedicated machines for playback of 4-track tapes but making a nagra even more versatile wouldn't hurt :)

Well you're stuck with a minimum playback speed of 3.75ips which is possibly unsuitable for many tapes (I don't remember if commercial rtr tapes were 3.75 or 1.87) then it's just an ugly matter of wires perhaps snaking about an otherwise beautiful machine?

 

For those here unaware of it though check out the classic David Lane Nagra playback machine, which was developed as a budget Nagra T replacement for transfer houses/radio - no record but mono and stereo playback heads (and synchro) in I believe a IV-S body to cope with the variety of Nagra recorded tapes coming in.

For a homemade version (yep I've thought of it too) it could be any Nagra (like a 3 or IVL) so long as the transport works OK ...

Commercial reel to reel tapes were either 7.5 ips or 3.75 ips.  Vintage amateur reel to reel machines were usually built with both of those speeds available.

Nagra used to sell 1/4 track Playback heads for the IV-S and Nagra T-Audio (same heads), but they are no longer available. You may be able to find a few of these Holy Grail items via eBay or internet search. 

Nagra Part# 7106.225.000 if that will help.
