Anyone know why the power amp is working, but the pre-amp section is not communicating with the power section??
 
I have tried that, but it never hurts to try again. So I did so and had zero luck. Thanks anyway.. Do you have another ideas??
 
Does anyone know anything about this amp. I loved the sound, although I have several great tube amps. I am thinking, when replacing the battery, I may have installed it the wrong way. I would really appreciate any opinion about what could be wrong, with it. Thanks guys.
