    The external speaker jack changes the tap on the OPT from 8Ω for the internal driver to 16Ω for both. As you correctly surmised the two drivers are in series.

    What are they asking for the amp?

    one of the transformers is not new, if Power that's fine, if output i'd be cautious, that's a big chunk of the tone there. also cuts the value down. re-cap? 4 prong speaker cable or updated to modern type? original tubes or new ones?

    any mods to the circuit? what speaker does it have?

    tons of different things with old amps.

    Hi - Very sorry everyone, this is a duplicate post. When I tried creating the first post, it seemed like it failed, and I was not seeing the post in the forum, so I created it again. The one that has gotten most of the traffic is here:
    60's Ampeg B15-N: Things to look for?
    So I'll see if I can somehow shut this one down so there aren't two threads.
