I've also built a few tube amps and listened to a fair number of valve & tranny amps, though not 100s. Sure their foibles are different, with neither being perfect. My experience fwiw is I've never found any tranny amp that has the sound quality of a Quad II or a Sansui 500A. I used to be more involved in audio, not much now. NT |

Both have serious measurable and audible flaws. -- Trevor Wilson www.rageaudio.com.au |

One of the motors from the eBay choppers fixed it, hurrah. I bought four more for use as actual optical choppers for proof-of-concept instruments.
