they were not lost, just in storage:-) It seems the mic in use at the proms in 1978 would have been MKII no 504, as 505 was in use at Nimbus at the time I went to the RAH with Bob to set up for the proms. I had been at Nimbus the previous week and left 505 with them. In February 1979 I sent a draft eq curve for the MKIII to Clem at Calrec, based on measurements they supplied to me from the prototype. I also have notes of schematics I sent to Ken Farrar later in the year which subsequently emerged in the MKIII control unit. And the MKIII was then used at the proms that year as we had surmised. Incidentally, my diary notes say that the IBA had (two?) MKII sfms down at Winchester, it would be interesting to know their serial numbers and where they are now; they did not get there via Reading but direct from Calrec. There is a note in 1978 that I purchased some capacitors to replace some in those units. My recollection is they were coupling capacitors, breaking down due to inadequate voltage spec for the 50v phantom. rgds, Geoffrey _______________________________________________ Sursound mailing list [email protected] https://mail.music.vt.edu/mailman/listinfo/sursound
