If you are interested in the OPTU, here is a PDF I made that has alot of the internals of the OTPU.

Oh, just remember there is no leg No. 4.
Also, behind the circuit board, there is a toroid coil just like the center toroid in the FTPU. You can only see it in one or two frames. lol

It is not 100% but there is a very good start.

All the best. I have always liked your work.

There's a battery in there somewhere though, no matter how small

Agreed P99, I recall reading somewhere during my research that a battery was not needed in the device... 'other than to get it started'!

So I too believe that there would at least be a button cell somewhere on the unit to 'kick' start the oscillating cct. After that I guess a simple feedback loop would suffice and the battery would be switched out of cct.

Hi Wattsup,

Thank for the document, certainly you have studied these photos in some detail.  I will check it out more when I get home from work.


Regards,

Dave.
