Yes, it looks like the Radial electrolytic capacitor (1000 uF, 15V), next to transformer, also received more heat. Clean board area with isopropyl alcohol.
I would highly suggest you look at the Panasonic EEU FK series (Digi-Key stocks), or other equivalent Panasonic 105° series https://industrial.panasonic.com/cdbs/www-data/pdf/RDF0000/ABA0000C1015.pdf I used the EEU-FK series for a 12 year old ESE Master Clock repair this summer (bulging caps in DC filtering section), that used inferior 85° electrolytics imported from East Asia (California shell company). greg, w9gb == Date: Mon, 28 Sep 2020 15:37:43 -0400 From: Patrick Tanner <[email protected]> To: [email protected] Subject: Re: [time-nuts] New member, new old 4040A with PSU failure Have made some progress. Looks like bad caps. Capacitor "CA" is especially naughty. https://photos.app.goo.gl/Ye91Fv4Nmuj4xb7n8 _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
