Hi,

Please check T1 and T2 for proper lead orientation, R1 thru R4 and C1 and C2. It should blink, especially if it's purple! ;D

Cheers

The pinout is ECB and it's placed ok. Could you please take a look at the datasheet, maybe you will see something that I've missed. Maybe these TRs are not suitable for this circuit.

as a general purpose transistor it looks good to me... btw, a reversed D5 can stop the LED from blinking too....

Hi all, I'm putting my Mouser order together for the Speaker Protector and Softstart boards and I could use some recommendations. Can anyone point me to Mouser items for the Euroblock, Faston terminals, standoffs, and LEDs?

Also, how about a set of gold plated speaker binding posts?

Thanks!

Hi, I'm also putting together the part numbers for Digi-Key, unfortunately it's not finished yet.

That terminal block looks ok. As for the faston terminal this one should work ok 63949-1 TE Connectivity / AMP | Mouser

I use whatever I have in the DA parts Bin. I tried red, yellow, blue 5mm and 3mm rounds and some rectangular too no problem. Just workout their lead orientation, otherwise they won't light up.

It's more up to your liking really.
