I have managed to get this amp working.
Thanks again. Couldn't have done it without your help.

I have determined these diodes to be ON Semiconductor MURS120T3G.

I found a diode (D17) that has failed (shorted out). There are 3 of these types of diodes present (D17, D24, D25) and they are all in close proximity to the IR2184S chip. The other 2 are fine. They are SMD diodes made by ON Semiconductor and say "225" and "U1D" on them. Does anyo...

I have removed the rectifier diodes from the board. It runs in a stable fashion (using 320mA when run at 9V, or 420mA when run at 12V). The LED is blue. When I ran it with the diodes installed, it would use as much current as I gave it, including all the way up to 3A (for a second, before I shut it ...

Cheers for the info. I finally had time to get this off the shelf today. As it turns out, it was going into protect mode when there was no speaker connected. When I connect a speaker and then power it up, the LED is red for a couple of seconds then turns blue. I will continue this repair and post th...

I've gotten this amp into much better shape, but it still powers up into protect mode (red LED).
Are there any particular sections/components I should focus on?

Thank you so much.

I'm repairing a Phoenix Gold Ti2 1300.1 and have found several faulty components. Among them is diode D21 (next to transistor Q81). It has failed short, so I have no way to identify what type of diode it is. All I know is that it's a MiniMELF with a blue stripe at the cathode end. Can anyone tell me...
