PS-100 No sound

Hello,

I’ve had my PS-100 for a few years now and it just recently stopped working. It powers on but no sound. I went through all the steps for it not having any sound and found the internal fuse was blown. I replaced it and powered it back on and a saw bright flash from the left power tube along with a loud pop. I assume the power tube is bad? Is there anything else I can check for? Thanks for the help!

Hi Gary,

Welcome to the forum.

Your description definitely points to a bad power tube. There isn’t anything deeper you need to be concerned about at this point.

We’re recommending JJ 6550 for replacement lately.
Sounds like you have the fuse sorted out too, but just in case, here are the relevant links.
