My grandson recovered a LANEY BC 250 bass amp, transported to sleep in a car, and with the vibrations the connections came out of their supports (I'm looking for photos of the interior of the amp) to be able to reconnect the connectors.
I have another problem on the same amp, there are two MOSFET transistors SM 3177 A and SM 3178 A which cannot be found.
Can you find an equivalence and which ones? not to do .
Thank you EGS
