Video about the 300P RM amplifier.
Have a look for ideas before you chuck it in the garbage.

Your mileage may vary.
Linear Power Amplifiers, particularly those using Thermionic Valves, have extremely high voltage inside that will probably kill you if given the chance.
Short Version:
1. Life middle leg of TR3 to disable pre-amp / pre-amp relay
2. Make sure pins 1-2 are jumpered (old models) or PA section will not work.
3. NO MORE than 5 watts input.
