Its been a while since I have uploaded, trying to make a video with a Canon 7D camera isn’t the easiest. Recently I was given a complete BTR-2 machine which spurred me on to getting my other 2 dead machines working, even the one which had the wiring loom cut in multiple places. If anyone has any spares for these machines or a complete one they wish to sell I am always interested.
These machines have been used around the world, most famously in Abbey studios, before and during the introduction of the Studer J37, the BTR-2 machines were very common, later came a very rare BTR-3 stereo version which was not as successful, many of The Beatles records would have been mastered on these machines. The recorder started life in 1952 and many were decommissioned in 1980, the BBC modified them to stereo which gave them another 5-10 years life as the recorders mechanics were so well built, they showed very little wear and tear.

Studer C37

Built in 1960, told to be the best valve reel to reel ever made, it is said that Willi Studer saw one of the Ampex machines (probably an Ampex 300 or 350), he was so impressed with the recorder he set out to build a better machine. The C37 by far blows away the Ampex and any reel to reel of its time for build quality, though I have not had an Ampex 300 or 350 to listen to I could not personally say which really does sound better.

The recorder was a stereo version of the famous J37 which was used in the beetles recordings, the C37 was the first stereo professional reel to reel to come from Studer and it also marks the co-operation with EMT Wilhelm Franz and Studer, the recorder boasts a recording frequency of 20Hz to 17KHz +-2db on 7.1/2 or 15 ips, this one records 20KHz on 15ips with +-2dB though a world famous designer Tim de Paravicini can modify these machines to record 20Hz to 35LHz +-1dB with a S/N of 90dB! This is beyond CD quality as 90dB noise is not detectable and CD’s frequency output is 20KHz (Half the digitized sample rate).
