Hi All

I'm soldering the Diy PA3004 chip PCB substitute, and can anyone confirm which is Q1 & Q7 lol

Is Q7 the highlighted one ??

Thanks

I can't confirm 100% but it looks to me like you highlighted Q1 and Q7 is above it. Did you buy it from affinity for artifacts on eBay?

Hello - I laid out the board, so I can confirm - the highlighted footprint is indeed Q7 - good luck!

Hi Alex

Thanks for the reply but unfortunately, evenafter replacing the Chip, I'm still not getting any relay click

If you post the model you're working on, and the voltages (pin 7 should be an AC voltages - the rest are DC) on each pin we may be able to help you troubleshoot further!
