try to check interconnection on your board. those that are rounded on green should be interconnected with each other. hope this might help. this also my problem when i first fired up this pedal.

Thanks to Sir Baja and DrNomis, after taking a long hours of tracing and trouble shooting, at last I made the tube driver works. Here are some screenshots that I made. https://i30.photobucket.com/albums/c337/metronome/Mobile%20Uploads/DSC00693_zpsosjeb7rl.gif https://i30.photobucket.com/albums/c337/...

For those who are still puzzled with the wiring, here is the diagram that I made. Hope this might help.

yes sir, I am from manila. So all that I need to connect from power supply is 0 and 12. How about supply going to the board? is there a polarity issues? or it can be interchanged?

DrNomis, thanks for you help. the orientation of the parts are correct. I found out that the capacitor voltage is 16v instead of 25v. :slap: I have one more question, does this tube driver uses 12v or 24v? Am I using a correct power supply (12-0-12 both are +12v=24v when you test it on a multi-teste...

Sir Baja, I need your help. I have attached a picture for you to see if I am on the right path to this project.

sir baja, what would be the connection of the transformer to the pcb board, if i'm using a 12-0-12 vac transformer. I have inserted an image for your basis, except that the image indicates a 25-0-25 volts. thanks.

Thanks for the quick reply, I put a 1/4 watts on the side of the supply and the 470 uf caps blown out and all the parts already messed up like resistors and diodes.

my question is regarding your 2 sided pcb layout. I dont know the wattage value of the resistors that I will put, is it 1/4 watts or 1 watts? thank in advance.

sir baja, what are the wattage value of the resistor? thank you.
