hello keo: HELP. i have wired charlize carefull according to your instructions. input voltage is negative at the board only, as you indicate, but i keep getting 12 volts dc at the outputs. i have gone over the wiring many times. there are no shorts. what do i do next?

charlize2 pcb has very clear markings on the pcb denoting 12v and gnd.

Hi, I have got a Charlise from a friend but am confused (as the one i got is naked and has no wires pokeing out of it)

The web site for charlise info says the following:

Important!
Please note that 12VDC is wired to square via of J1 and GND is wired to round via of J1.
when you receive Charlize, the white wire goes to 12VDC and black wire goes to GND.
Mistake here is catastrophic! Charlize will leave you forever!

However the photo shows the a caption stateing
12v DC ground going to the square land (not to the round) on the PCB and clearly contridicts the above, so if i get one its 50/50 chance of killing it? :cry:

Please definatively state which the round and square polaritys actully are in relation to Charlise polarity.

Cheers

johnny

I just received the two Charlize2 modules I ordered... carefully connected they lie on my desk and now work like a charm - did not like a programmable switching power supply (lab gear) firsthand, so I hooked them to a 12V motorcycle battery instead, and let them drive vintage two-way Braun L-550 speakers.

Thanks so far for rapid shipment half around the globe!

Both Charlize2 girls enjoyed new years eve and some days off in Almaty, Kasachstan... but today arrived unharmed thanks to being well packaged.

I guess it is now correct to let them accommodate a little before they face the real task: a direct comparison with a Radford STA25 MkIII valve amp 8)

What I have heard so far is quite promising. Let´s see...
