The DB25 pinning is as per TVB's web site: http://www.leapsecond.com/museum/e1938a/ The EFC voltage info is as follows (courtesy of Rick K): *** The 10811 was bipolar +/-5V as you said. The cathode of the tuning diode was connected to a 6.2V zener diode that was sort of ovenized. The concept was that if you did NOT want to use the EFC, you simply grounded the EFC pin. The E1938A has unipolar 0V to 5V EFC with the anode of the tuning diode grounded. A 2.5V reference IC that really is ovenized provides a stable 2.5V to bias the diode if you do NOT want to use the EFC. *** I concur with Bruce's on-board LED description. My experience is that the "hockey-puck" oven takes close on 15 minutes to "stabilise" (settle) - in the Z3815 at least !
