Hello, sorry for my english. I read the forum with a translator.
Today i've made the vanilla overdrive. point to point wired. I did everything like the pdf layout and the pictures. When i power it on the heaters glow, i measured everything.
i have a 12.4v power supply, 6.2v on each heater. on every cathode-anode i get a voltage, i don't know them by heart anymore, but in the first tube i got around 7 volts, the second one a lot less.
When i power it on the heaters glow, but i only have humming noise, no guitar. i use JJ 12AU7 tubes.
Could anyone help me by giving some tips or so, or could it be my JJ tubes? I realy have no sound exept for hum. I rechecked everything many times, and I can't find anything wrong or missing.
