Well done Ziggy, I for one am grateful for your efforts, I commented previously
on the high standard of construction but I couldn't believe that the angles of
the screw slots at the corners of your schematic are identical to those in the
lid of my TS65! grin

Well, it's still probably better than nothing, even with the missing bits. It's
kind of an interesting little box and the lack of a completely unencumbered
version of this manual really annoyed me. So I've posted a complete PDF version
on my website for those interested. It's a little hefty at
I know it's generally bad form to reply to my own post, but if you downloaded
the manual already, you may want to do it again. I found a copy of the complete
schematic and updated the manual, inserting the schematic where it should be.

Thanks Bob,
If it helps the switched frequencies are: 0, 10, 20, 40, 60, 80, 100, 120, 140,
160, 180, 190Hz.

I have complained to Google about that scanning issue. IMO, it's a real

In a few years, Google may have the only extant copy of some doc.
And it will be near useless w/o the fully scanned pages. This is the third
