Hi

I am working on the above amp and realised that the power IC, STK043 has blown up. This IC is totally obsolete. I compared the data for this IC with STK460, both are rated 20W, 32V. Can I replace this IC with STK460 or STK465. Please assist

Thanks

Carlos

These are New Old Stock.

Actually, those are fake. Original parts do not have the four digit code in the top (most fakes do) and the printing is never that clear white, and never that crooked.

I live in a country far away from civilization. Therefore it was necessary to repair the hybrid chip. Explodes only output transistor. You can open the enclosure and replace it externally. So I repaired during the USSR.
