Hello folks! Wink i'm new to this forum and i've very pleased with it since it might solve my problem.

I Have a Pet Raccoon and he climbed my amp peeing inside it, he blew one channel, so i open the amp and started searching for what went wrong

i found that both output transistors blew (the MN2488 and MP1620 if i'm not mistaken) also the 0.22ohms emitter was broken so i got a replacement.
A Small A988 Protection Transistor was also damaged so i got a new one (2SA988 if i'm not mistaken), a Resistor that was in R7something something blew up so i searched on the internet and found out that it was a 1k 5% 1/4w Carbon Resistor, Sony Confirmed that.
Another Resistor, the one that was attached to the A988 blew up also..., so i cheked on the channel next to it and found out that the resistor was a 1.5K's so i got a new one (sony confirmed that value also).

Now the channel is working but it distorces, specially the bass.

Some guys told me that it might be the Resistors and that i should check them out, but some of them are fading their colors, so i really need a shematic for every resistor in the Surround Right channel (the one next to the Front Left i think).

Well i hope to get a reply, thnks Wink
