Re: Need help diagnose dead Sunshine ATX235 power supply
Hi,
Anyone still reading this thread? Is this el cheapo chinese low quality psu worth the time to repair since I wish to use it as a learning experience; and it is not for use on any data sensitive pc. The likely usage will be for test bench on old 90's(Pentium 4) era motherboard.
FYI, the C945 driver transistor on Q12 base is connected to pin 11 on collector output of KA7500B while C945 driver transistor on Q13 base is connected to pin 8 on collector output of KA7500B. Earlier on testing them off circuit with a DMM on diode test gives a near identical (between 591 to 594 ohm) result from a new C945 unit.
Hoping to hear your generous and helpful reply. Thanking in advance.
