So I am done with the amp…well sorta…
Its seems to be somewhat working but no guitar sound!
The power is fine, and the tubes seem to work, at least they are lighting up. I have not checked the voltages while its on, yet. I am a bit nervous to try it yet!
Anyway I just get a loud hum from the speaker and the volume knob seems to have no effect. So I have two questions….
1. What is the correct wiring of the input jack> Its seems odd to me like we are wiring all the 3 tabs together? There is a 1M resistor running from 3 to 1 and and wire from 2 to 1? then 1 is grounded and sent to the mini switch as well as to the 1.5K resistor? Is all of that correct? I feel like that is where my problem is but not sure.
2. Well just wondering if I had some wires too long, say like the input wires from the jack to the board, would that make it motorboat? Is that the loud hum I hear? Any help would be awesome!!
