Hi Tom/ Conga issue SOLVED

Hi Guys,

So am taking my time working thru the build on my Yocto kit, checking and testing everything as I go.
But now have just run into a issue with the Hi tom/ Conga.

I am testing the instruments each time with an arduino 1ms trigger pulse, all has been fine so far but am unable to trigger the Hi tom from R269.
I've got 5v connected to R267 btw.

If I connect my trigger pulse to R270 it works fine.
I have swapped out Q57 with another 733 Transistor but the behaviour is still the same.

Any help would be great!

Hey Steve,
maybe triple check the values of the resistors R269 until R271 and the the transistors Q56 and Q57.
If those check out correct, try to reflow the solder joints.

Ok, so I now have a working Hi Tom

Swapped out Q56 for a spare I had from a dead TR606 board, and all is now fine again!

Thanks
