Speedball Upgrade. 2 LEDs are off = D1 Diode was not functional. [resolved]

Yes, there is an issue either with the small PC board, or with the wires that connect it to your Crack.  If all else fails, you can contact replacementparts(at)bottlhead(dot)com regarding a replacement PCB.b

Thanks for the bump and feedback.

I will give this a close look over the weekend and report back.

I'll bump this for you.

My guess would be something wrong on the A board.  The suggestion above of disconnecting the A side from T1/1U, T2/2U and replacing the 22.1k resistor across those terminals should confirm this.  I would expect both socket LEDs to light up and better voltages at A6, B1 and B3.  I would suspect the D1 diode or 2N2907 transistor.  Since you wrote that new diodes were ordered, you might want to try replacing that diode if re-flowing the joints on those two components doesn't/didn't fix the issue.  BUT, I know very little about electronics.

Best would be if someone who knows something about this stuff answered this thread.

SOLVED!! the problem was the D1 diode, thanks for the tip

Finally, me issue has now been resolved, thanks to this great community here.
For those interested, I attach some pictures of my Crack setup.

... This is going to be a great Sunday

I really like the combination of the black paint and the finish you did on the base.
Nice job. Enjoy!!!

Thank you, The credit goes to my dad.. He helped me with the woodwork this summer when I was visiting him in Iceland.
He is a well skilled handcrafts man.

Out of interest, did you use one of the eBay LED's as replacement for your u/s one? Would be good to know if they are correct as I have added some to my spares box. Thanks.

Deluk: I bought these as spares. Doc said they were the correct ones. £3.30 + £1.99 to Dk.

ElGringo81: Yes correct. I did and they work perfectly. Thank for pointing me in the right direction there

Thanks for the confirmation, good to know that there is currently a European source at a not unreasonable price. I have to fit my Speedball yet, probably over the Christmas period, but would rather not have to replace any of them on those boards either.
