    Hi Guys,

    Using a CIOKS AC10 to supply my AA6, and I was using output 3 with dip off so 9V DC 600ma. All running fine.

    Seeing the stated requirement for 800ma, I switched to output 5 with dip off so 9 or 12V AC, 800ma. AA6 booted up so far, but hung on the firmware notification screen, with 9 or 12 V output. I thought the AA6 was supposed to be OK with AC.

    Switched back to output 3 with 9V DC, 600ma, all OK again.

    Just wondered if it might be the difference in cycles between the UK (me) and US. Any ideas?

    Cheers,

    Paul

    Paul,
    I'm not sure what's going on there.
    I'll send this to the design team to get their perspective.
    I will say that I've heard about nothing but trouble with CIOKS power supplies
    from AmpliFIre users. However, I've heard nothing but positive things
    about the True Tone Pro power supply products from our users.
    So while I don't know what the trouble is yet in this case,
    if you want to bypass these issues you might think about switching
    to a True Tone Power supply.
    https://truetone.com/cs6/
    They work a little differently than most.
    From their website:
    A major benefit of using a switching power supply is that it can handle far more current (power being pulled out of it) than any transformer-based power supply. Although we had to put power rating labels on each output to satisfy certification agencies (yes, we actually certified these, unlike most companies), the outputs can generally handle far more than the label shows. For example, you can connect a 300mA pedal to a 200mA output, without causing any problems. With a transformer-based power supply, you can’t get away with that. The important thing is to not exceed the total of all the labels. With a CS7, the output labels add up to 1900mA total. That means the total current draw of all your pedals should be less than 1900mA. That total current rating is roughly double the current load of the most common power brick, for a lot less money.

    Thanks for the quick response and reply.

    I have used the CIOKS for many years now, with a loaded pedal board including a valve pre-amp taking 16V. Nothing else fitted the bill at the time, and to be honest it has been great.

    Like I said, with a rated 600ma output it runs the AA6 fine, and I guess this is because with my new simpler board I am nowhere near max load for the CIOKS.

    Let's see what your guys find - maybe my CIOKS has a fault, but if so it is an odd one..!

    (Great product by the way!)

    Cheers,

    Paul

    Hold fire until tomorrow. It's possible that I need to set another dip to use the 800ma AC section instead of the 600ma DC section.

    What threw me was that it started to work and then froze, but maybe the voltage or current of the inactive AC section is way down when not activated with the dip. I'll let you know..

    Hi Jace,

    Yup. I had failed to enable the CIOKS 800ma AC section with the dip switch. Long time since I originally configured it is my excuse o_O
    Now working fine on 12V 800ma AC, and it is clear that the CIOKS now has more headroom as the indicator LED is now 'breathing' more slowly.

    Thanks once again for the quick and helpful response, and apologies for not checking more carefully here before reporting.

    Cheers,

    Paul
