1. [Amps] Time delay problem with an ALPHA 76 CAE (3tubes). (score: 1): Author: "J.H Mauduit-Larive" <fr5dx@wanadoo.fr>; Date: Sat, 13 Dec 2014 09:15:52 +0400; Hello, I have an Alpha 76CA #SN 6704 (October 1983). The amp has been stocked for about 10 years! When I press the ON button , the panel meters illuminate amber but do not change to pale green after; /archives//html/Amps/2014-12/msg00049.html (7,074 bytes)

As someone stated the problem is probably C109 (22 uF, 20V) on the HV & Control PCB. With R120 this RC delay circuit controls the time delay. If your actual delay is less than 3 minut; /archives//html/Amps/2014-12/msg00052.html (7,682 bytes)
