If the buyer needs a copy of the manual I can make one. (yes I have contacted the person who made this item and he has lost 100% interest in this product....)
Also I read a thread about wanting a laser oscilloscope. Just put this is dot or line, and feed the audio into the x or y input and there you go. Laser O-scope.
But no more then 1volt!!!!! Or damage to the internal amplifier circuit can happen.
Also is this the C2 or C4 version? The C4 version would run 4 heads, and had a stronger amp circuit.
Someone buy this so I am not the only one still using the beam scan on this forum.....
