I am attempting to bread board my first pp amp, so of course I run into something I don't understand right out of the chute. In the schem below I believe the plates of the 6v6s are connected to the primary leads of the output trannies, but what is grid #2 from each tube connected to? Thanks |

Got any suggestions? I want something simple using 6v6s as the output tubes. |

Interesting. Not sure if I have any 5965s though. I will have to check. Thannks |

You'll need push-pull OPTs, so 5965s aren't the only thing you don't have on hand. Dave |

The 125e is a push pull opt. |

My apologies, I read "se". With a low frequency rolloff at 150hz, it's pretty limited, good luck. Dave |

I will probably try them one of these days as money and time allows. |
