I am rebuilding a valve amplifyer for a Seeburg 148 music box.
I have finished the rebuild of the main amp and have the pree amp to do.
I powered the main amp up with a load and every thing is ok but the audio power amp is down in resistance between the center tapping and the other two takings . Which causes a audio problem.
I am looking at punching a new transformer but the only information I have is the voltage in and out I need to find out the power rating of the transformer.
Can somewon help me with this.
I will post a circuit
