Good afternoon, my name is Nicolas, I send greetings from Argentina. I want to ask for help with a problem I'm having. I have a old power supply Daiwa PS-304 when lit noticed that the volt/amp meter is not working. Well, is not very serious problem but when I measured the output is only 12.8V I check the key voltages in a diagram found in a post in this forum. But now I do not know how to go and find out the problem. (Sorry, my English is horrible) Voltajes Outputs Transformer Main=18 VAC Transformer Sec= 5.5 VAC PS Max Output= 12.8v Rectifier bridge= 24v The next values was measured with volume in the middle. I think must be 13.8v (I have 11v) 8230 board Pins: 1=6.5v 2=5.44v 3=.315v 4=10.9v 7=11.9v 15=23.5v 13&14= 5.5 vac IC1 Pins: 1=.638 8=9.72 2=28.6 9=3.06 3=15.2 10=3.06 4=30.6 11=0 5=12.8 12=6.37 6=12.4 13=6.37 7=29.5 14=14.59 C1815 Transistor: E=13.8 C=30 B=14.5 Any ideas?
