"content": "Oh no! My trusty old Thurlby Thandar PL154 bench PSU (15V 4A) suddenly went wonky. Voltage control worked, but current limit didn’t and short-circuit current was only 16mA.\n\nHmm...old caps, sense resistor, emitter resistors, or the bank of 2N3055s... \n\nDug out the schematic, put the PSU on the bench, started opening it… then noticed the banana socket pillars were loose and the sense straps effectively disconnected.\n\nTightened the terminals.\n\nJob done.\n\nShould have checked first.\n\n#Overthinking\n\nhttps://files.mastodon.social/media_attachments/files/115/864/499/921/897/148/original/01749aaa45e36348.jpg\nhttps://files.mastodon.social/media_attachments/files/115/864/502/432/110/728/original/67d34a44f8dad309.png",
