DT-500 malfunction.

[eiraved]

I did find a few on Ebay. One was promising until I asked him to set the time to see what happens. He did, and the time started going faster on his, too.

Too bad you missed out on the two I sold here recently on BT, both fully operational. Try a WTB on BT, it couldn't hurt (not affiliated).

I did Mod 1 on post #3 of the article I referenced above on my DT-510. Today I posted to that thread asking if the solder points shown on that DT-510 would be the same on a DT-500. If the solder points are the same, I may be able to help. I can't read a schematic but I can solder,
