hi folks,

a while back i started working on an external RGB amp for the PC engine/Turbografx,
and after some experimenting on a protoboard decided to make a limited run of these.
fellow member KRZY was kind enough to draw out the pcb,
and after some further tests i am glad to anounce the "TURBO MULLET" in its final form.
it uses the 7316 instead of the more widely used 7314,
and has a significally smaller footprint than previously available amps.
it has 2 jumper settings to choose RGB with either composite video or Csync as sync,
and for straight composite video.
alternatively a switch could be fitted to switch between RGB and Composite.
it is designed to work with MD2 cables, composite cables with composite jumpersetting will output composite,
RGB scart cables will output RGB with the jumpers set to RGB.
i would advise caps and resisors to be removed from original scartcables as signals are already terminated at 220mf and 75r.
also, better cables will provide better image, so those used with the Terra Onion for instance would work perfectly,
aliexpress cables will work too, but there is a chance of visible interference.
i assemble these by hand, and test before shipping.
price is $25 each,
contact me for shipping options.
