Only the jacks on the amp itself are series-connected. Cab-to-cab connections are still parallel.
Yes, which is why, in my original post in this thread, I recommend the exact same solution you later did.
If you put a 16 ohm load across the 8 ohm tap, the net result would NOT be less power, but more
You wanna double check that? Am I missing something? I've been working off of the (corroborated) assumption that increasing the load (without changing the output transformer tap) lowers output wattage and vice versa.
To use a terrible example (SS amp not tube, no tranny but also no selectable output Z) because this sort of spec is somewhat irrelevant for Tube amps with selectable output taps:
The lower the secondary load, the more wire is physically required in the transformer to induce a current at that impedance. Putting the output jacks in series effectively limits the amount of current the transformer will be asked to supply.
But current is a function of load and output voltage, which are (or can be, given the assumption I requested) constant whether or not the jacks are series or parallel (unless you mean that by making them series you somewhat impede, though not eliminate, the user's ability to attach a lower load... which seems moot anyway because either the amp handles a 4 ohm load or it doesn't). Are you saying that this is just a way they don't have to worry about someone trying to attach a 2 Ohm load (either by accident or because they think 'close enough') and therefore the tranny doesn't have to be as beefy? Becasue that I understand, but is, IMHO, a stupid business decision (especially given the fact that Leo never really used very good output trannies to begin with; that was part of the original Fender sound - easy saturation).
.... yeah, I'm one of those knows-enough-to-be-annoying people
