Panel dimmers - repair or buy PWM

It would be possible to remove the transistors and little bitty fuses and just use the existing rheostats.

It's a low power, signal potentiometer used to drive electronics. It can't handle the current...

I have 8 nulights so that's 1A in total there. At full blast, they dissipate 14W. So if I want a pot to dim them down to 50%, I need a 7W pot minimum. 15W to be safe. 

I called Seaton engineering and told them the issue. I think it's past warranty but I asked them to either repair it or take it back as core. I'd feel really bitter to spend another 400$ because their product broke down. I get it, warranty is 1 year but stuff shouldn't break that quickly...

I think the pots that are there are higher current than you think, The nulights are a bit of a draw.    Several solutions here.
