Okay, I have a similar problem, though I have a schematic to work with. I know the old diode is labeled PH C15 but I’m not sure what wattage. I was advised by an engineer friend to order a 15V 500mw replacement, but it’s half as thick as the original, so I’m thinking I need a 1W instead. I’m looking to replace diodes in a power amp circuit. It’s an ambitious project because the board has fried. But hey, I’m learning a lot. I’m reading it as diodes D5 and D6. (Mostly because I can find D1-D4, and D7 + and not those two)

The opposite side of the board appears to have a duplicate set of diodes, as well as duplicating the resistors, that giant cap, and two mosfets.

15 V, 500 mW is probably o.k. Size is not a perfect indicator of wattage.
I'll put these posts into a new thread as you hijacked a 4 year old thread.
