Blackstar HT-Dual

 Finally a faulty Blackstar pedal on my bench.The grouse was the LED's were blinking abnormaly.The fault was a spoiled power regulator.Due to that it was uanble to initialize.
Built wise its bigger than I thought,tough and yet elegant.Looking from the front,I wonder whether changing the Tube will be that easy.No time to find out,on to the Net for the schematics.
I didn't use glove's when repairing it.Burn fingers and eletrocuted was part of the program.

One heck of an awesome pedal. I'm targetting for this one next.

I read somewhere that changing the tube is pretty straight forward. You can unscrew the grill and take the tube out just like that.

Hi Bill,

I saw something online that looks like a close to a legit schematic 6 years ago. I did saved it but I don't know whether I still have it. I had changed 2 pc since. I suggest you check the regulator ICs'(Three leg) in and out voltages. Touch with finger if any of the IC DIL 8 pin to see whether its abnormally hot. I believe one of the DIL 8 pin IC (IC5) is also some sort of a regulator.

I hope I have been much help.Thank you for visiting this blog.
