Following your comments, i have opened the enclosure, disconnected the power supply and measured the fan current ( 40mA) when connected to AC line.
Ordered a 4020 model 12V with the proper current, seems very common
My 53132A will be back on stage very soon
Thanks for your help.

A very normal “spiral of death” on the 53132 is the fan going out and the power supply following it a month or two later. The supply apparently does need the fan cooling to keep it happy. Since the fan runs whenever the counter is plugged in, the fan logs a lot of hours. If you do loose the power supply, the one in the 53181 will swap over to the 132. It’s not a cheap fix, but better than scrapping a 132.
