Today, I found an ACHME PSU (model AM318L) in a Teac DV-B100 digital terrestrial set-top box. A search for this supply revealed that this supply is also used in a Sampo DVE-560 DVD player.
The circuit of this supply can fbe found on http://www.eserviceinfo.com/download...c_DV-B100.html
It also contains information on the brand and series of electrolytic capacitors used in certain locations.
This set-top box has been running for about 5 years and there are no bulging capacitors (all of them were original); however, I decided to upgrade the 22uF 400V unit to a 47uF unit.
Is the circuit of this power supply a bad design?
