There may also be line voltage issues at work here as well. An old, departed friend used to be Martha Graham's recording engineer. He carried a box the size of an Ampex 300 case with transformers within so he could played her company's dance tapes back powered by the trolly lines in Thailand, etc. Steve Smolian ----- Original Message ----- From: [log in to unmask] To: [log in to unmask] Sent: Thursday, March 04, 2004 4:33 PM Subject: Re: [ARSCLIST] Odd Speed About 15 years ago a friend sent me his reel tape collection of interviews he had made while doing a religious news show on the BBC. He asked only that I might convert one or two tapes to cassettes for him. Upon playing the tapeS! I found they were, in fact, recorded at about 5 ips! I did the best I could at the time by increasing the size of the capstan until it came close to c. 5 ips. Evidently some recorders (for radio use???) recorded at 5 ips, or nearly so. Else, why were there several such tapes? Don Chichester P.S. The man was Rev. Eric Robinson, and his show was "Man with a Mike". He interviewed numerous famous clerics and theologians just after WW II.
