[GreenKeys] Wanted: Dovetron TSR-500 schematic

[Ralph Irish]

Gregg

I have both the schematic and the parts layout drawings.  They are 'blue-line' drawings
on a "D" sized drafting page.  I can scan them in four shots and e-mail the items to you
so that you might 'cut and tape' things to produce what you need.

Typical of old 'Ozlid drafting items', these are not absolutely 'clean and clear', but I
should be able to come up with something useful.

Let me know if you get no other offers of 'the real thing', maybe or ???

73,

Ralph - W8ROI

The problems involve the TSR-500 regeneration circuit board, primarily when it comes to the speed conversion circuitry and the LED drivers.  I have the schematics and manual for the MPC-1000R, but I'm missing the schematic for the TSR-500.  I've looked online and none of the sites with Dovetron info have it.  Does anyone have a copy they could email to me?  I'd also be happy to pay for copying/mailing costs to get a copy.
