Schoolie 24 problem

[geekmacdaddy]

Hey Guys and Gals
Voltages are all good on the big board but when I attach the daughter board, the overload LED just flashes. Made a mistake and reversed + and - on the DC jack at first, so I rebuilt the entire power supply. Even the 2N5088, but the LED is still flashing in the off position, and lights in a strained intermittent way in the on position. Any thoughts are appreciated.
Thanks
Jeff

Have you replaced the 1054 yet? Can you hear the relay working?

Hey Jimmy!
Swapped it out, same. Don't have the spider sense for that relay.
Thanks

Overload LED is oriented correctly? Does the flashing go away if you turn the Feedback all the way down?

[geekmacdaddy]

Hi Brian
Correct direction. No, it remains.
Thanks
Jeff

Would you believe (Don Adams

I was wondering about that. Those things are sensitive.

Son of a bitch sounded dreamy then let out a death wail. Unholiness in the midst of my cloud like modulated world. I'll hit the IC's and see what see. Tomorrow.

I had the same problem, sorry I didn't see your post earlier. I bought a few from a local (Australian) pedal parts shop, they are all bad. They apologized and refunded, I ended using a v571d from Cabintech.

I've used Xvive MN3005's with great success. (Edit) and Cool Audio
