Topward seems to keep their SMs and schematics Top-secret.

I have a schematic for the 6603A if that's worth anything to you. It is a 2MB pdf file... I'll try to attach it.


I have a 6306D and most of the power and control circuits (but not the display) are identical to what is in that schematic.


(Nope... even as a zipfile it is too large to upload.)

Do you think if one would email to my email it would work?

Upload it to k04bb, or split it into pieces.

Not much luck in getting a schematic for this so was thinking if I list the part numbers that are on the board I would be able to repair. I have 4-5 resistors and 4 transistors and one cap that are burned up. If someone could supply the value for these parts would be able to repair.

Best Regards

Thanks to all that sent schematics for my power supply but unfortunately none of them are close enough to repair the power supply.

Any ideas?

Best Regards

I have come to the conclusion this is the most keep secret Topward has. I have called sent emails to no avail so I have taken a picture of the board and mark the bad parts. Hoping someone has a board and can tell me the value and part numbers of the transistors and resistors.

Best Regards
