This site probably has the info you are looking for. Since I don't know the mfr of your amp, you may have to file thru more than a few pages to find your amp here.
Is it worth it?
Yes; it is probably in there somewhere...
The Silver Eagle amps were made in North Mississippi by the same person who built the TNT amps. You might also find them labeled as Comet. Probably not any info available or that I have seen on them. The 350 should have 4 MRF 455's or something equivilant.
