Maintenance update for the Echorec Bible. In order to provide the maximum possible accuracy the 1965 Echorec B2 entry has been splitted in two separate records: the B2 itself and the T5E B2.
A batch of B2 units, identified as T5E, was produced under the Binson C.R.E.B. label, while the B2 was produced under the Binson s.n.c. label. Please note that the same T5E acronym is used also for the 6-knob Echorec1 and Echorec2 models: see the Echorec Bible for details.
