I've got a dead Mission Cyrus Two amp, which was inherited from a mate a
couple of years ago. On looking inside, it appears that there are two TO220
packages which have had the tops blown off them, along with an 8-pin IC. The
part numbers, as best I can make out, are...

TDB 0137 SP
LM 317 SP
LF 353 DP

The 317 is a voltage regulator, and I'm guessing that the 0137 is the
negative equivalent of the 317. Does that sound right? I think the 353 is an
op-amp. The resistors adjacent to the TO220 packages still produce readings,
so I'm assuming that they're okay. I haven't powered it up to see if the PSU
is okay, and I haven't tested any other components (like o/p trannies).

I'm wondering if changing the blown devices might just effect a repair.
Before I get the soldering iron out, does anyone have a schematic for this
amp, or know where I can get one?
