Hello one and all, this is my first post to these forums!
I have a new tube amplifier on the way:
**broken link removed**
And unfortunately, it requires 16VAC at 50Hz or 60Hz and 1A.
As I am planning to use this for a portable microphone setup, I was hoping I'd be able to power it from a 12VDC 50Wh power source (a universal Li-ion 12V/9V/6V/3V powerpack to be precise).
I have spent several days scouring the net for circuits to efficiently convert the power from 12VDC to 16VAC, especially while maintaining a pure sine wave (which as far as I'm aware is vital for good preamplifiers) and while skipping and intermediate 120V/240V stage.
Any and all help would be much appreciated, what I thought would be an readily available product has really turned out to be very rare!
Kind Regards
James
PS: My current plans are to use a pure sine wave oscillator amplified by MOSFETS to interrupt two voltage doubled 12V lines (one for +24V and one for -24V) which would give me the +/-22.7V range I need and eliminate the need for a transformer... but thats where my poor electronic knowledge fails me, for in the schematic world, I would burn toast.
