Hello all - I was given an Infinity Entra Sub by my neighbor. The sub is getting a little sound from the amp, but mostly distortion. I opened the amp up to find signs of overheating near some transistors/diodes in the power supply. I'm wondering if this is the cause of the amp not working? It should be easy enough to replace the parts to find out. The transistors I've identified easy enough - NEC D882 and B772 pairing, but I'm not familiar with diodes. The board says "ZD..." is this a zener diode? And the diodes say "15" on them - is this 15v, 1w? How can I tell what wattage I need? Any help on those questions and anything else that I might need to know before I order parts would be appreciated!
Also, to avoid having to purchase 10 transistors/diodes each off of ebay, if anyone wants to send me a few, I'll compensate you appropriately via paypal, I'd appreciate it. Thanks!
