The attached shows an 8 ohm load on a solid state amp, but in reality the amp is fitted with a 4 ohm load and has a broken (badly distorting) power amp stage. I'm planning to replace both power transistors (BD237 and BD238) and wondered if anyone can advise on the load. Most solid state amps can take loads of 4, 8 or 16 ohms. How can I tell if a 4 ohm load is safe on this when the circuit diagram shows an 8 or 16 ohm load ? Thanks.
