Title: Noise issues with my Crack w/speedball. Help!
Post by: shimacm on September 19, 2022, 10:16:33 AM

Good evening!

My Crack with Speedball is making very annoying noises.

I've already ruled out the possibility that the problem is with the valves and valve adapters.

The noise sometimes disappears when I disconnect and reconnect the headphones to the amplifier, regardless of the tubes and headphones you are using.

There is no outside interference as the amplifier works in the same place as always and the problem has appeared recently.

Can someone help me?

I would recommend plugging in an inexpensive pair of headphones and poking around the circuit with a wooden chopstick.  If you have a loose connection and you poke at it, you should be able to produce pops or noises through your disposable headphones and that can help narrow things down.
