gar1731 build thread

Hi. On two of my new 1731's I wrongly installed Q7 & Q8 in each others locations. I'm switching them now, but noticed there is now a solder bridge on the PCB between the third pin of Q7 and the adjacent lead of R12 (shown in green circle below). Is that bridge ok or should I scrap this 1731?

Thanks!

Get some solder wick and remove it.

Thanks!

Sorry, didn't clarify. It looks like the black coating has been etched off there creating an unavoidable bridge. not a solder bridge on top of the black PCB coating.

Thanks Paul

hey Paul,
just pulled a working 1731 from my gssl and tested - i have connection there too. you should be fine. no guarantee tough

The black masking is covering copper traces that are part of the design. If there wasn't a copper trace already there then any solder bridge made should be easily removed. Swap the transistors to their correct position and give it a whirl.

Looking at the overlay, that resistor is supposed to be connected to the transistor. You can get a volt meter and check this against Q8 and R13 as those two are supposed to be connected as well.

Thanks!

The connection under your Green circle is correct.

Completed my first GAR 1731 (and first ever DOA build) today. It works great in the CAPI VP25 I built over the weekend.
Thanks to Gary for a well-documented kit that was easier to put together than I expected!
