    So ive had this valve drive for a while, very happy with it. Until i turned it on and nothing. I changed the tube, didnt do it. I checked the jacks and switches.... and nothing. When my amp is all the way up i get a tiny signal from the pedal. Any ideas??

    The footswitches on those have a habit of failing.

    +1 and unless you're real handy with electronics, just take it in to a tech. Cheap fix. great pedal.

    im pretty handy with an iron, and ive checked all the switches with a multi meter and there all good. I was hoping someone else had had this problem, ill just get it to a better tech than myself.

    This just happened to my pedal also.
    First it lost volume and made loud "farting" sounds in the amp. When i tapped it to the floor it made some crackling sounds. I had to bypass it that night. The next day it was totally dead when engaged. Tried a tube swap but that didn't help. I have not checked the switch yet, but that's the next suspect...

    well sorry to say, but mine the transformer died. And ebs will not sell a tranny for it. So either re case it and use a new tranny or send it back if you can. best of luck, hope its not the trany like mine (sounds like it is)

    I was lucky. There was a bad solder point under the right switch and it was an easy fix. I also bought a backup just in case...

    I picked up three of these a couple of years ago on ebay. The transformer inside all three units was no good. I was able to get a suitable replacement from Mouser. I'm pretty sure it was Tamura brand, about $10 to $15 apiece. Also, if memory serves me, the voltage spec is on the side of the original. The Tamura was not a perfect mechanical fit on the circuit board and required pigtails and hot melt glue and a tiny bit of trimming of the bobbin to fit it. The new transformers were definitely heavier duty and performed flawlessly.
  9. How 'bout email EBS? They're really helpful.
