Thanks joecool,

(I got stuck in progress...)

My concern about the speaker-swap came from an exchange here (although some years ago) that the Vox Mini3 is (was?) peculiar about it and would fry the preamp if particular care wasn't given (like, the ground was not really a ground, etc.) Is this still a problem with the new issue of Mini3-G2?

Other concern – widely shared and confusing – WHY, oh Why can't be Lithium batteries used? The dire warning on the Mini states "use only alkaline AA batteries". Will it go "pooof" if I use a Lithium battery, output almost exactly matching that of the Mini's switching power's? My Lithium cell is 12v-3A (nominal) center positive, the Mini is 12v-1A (nominal?).
Is the pack of 6 x 1.5v AA (9 volts) better? I produce seemingly unending heaps of dead AAs week after week...
In general, perhaps a modern, universal battery powering system should be developed and employed (and it appears that the Lithiums is the way) instead of the clumsy, inefficient and expensive 4-6-8 x AA alkalines?
Thanks,

Hi Everyone,

I'm new in these hallowed halls and learning the rites, so have mercy...

In the age of "The Club Goes to the Street" I decided to build (assemble) the World's Greatest Street Sound System - under $ 100, weight 11 lbs., battery-run, pretty and disguisable.  I might need some advice... I'm a musician; I guess breadboards are for toast, no?

To a test I'd like to start with replacing the speaker in my recent issue Vox MINI2, 3Watt street amp. Also, take the whole thing out of it's cute, "boutique" enclosure. Then progress will follow to yield the above superlative.

I've learned (here) not to mess lightheartedly with that speaker-swap in this amp, so it still works. But the sound it does is not what I want. If possible I'd like to test it with 2 x 4" (5)", 90-SPL Visaton speakers - or better. Can this be done, and if yes, why not? (I understand Ohms, but there's more involved here).

Any advice pertaining to this and, consequently, to the Miracle Mini Monster System that will quickly follow is greatly appreciated.

Thanks

Paul
