WTB: DIY'er in the Bay Area to help fix my ZDS (likely simple loose solder joint)

I bought this recently here on SBAF and it took me a while to finally get it setup and listen to it and there's no sound in the right channel.

I've troubleshooted everything, swapped tubes, swapped the rectifier cables, swapped interconnects, moved to a different slot on my switcher, swapped headphone cable adapters, checked with another amp to make sure there was no headphone issue, etc.

But in doing all this while swapping interconnects, I got sound in both channels for a moment but it went away again when I changed cables again. So I'm thinking it's a simple loose solder joint that came loose during shipping, maybe even as simple as the connection to the inputs or the input rotary knob.

And this isn't necessary but if you're up for it, I'd love to swap the stock pot for a TKD while you're at it

I'll drop off the amp with you and pick it up as well

and I’m more than happy to pay for your time.

Thanks!

 

RD! I can help look at it but shipping will maybe not be fun
