Hello Everyone. I am new around here but have used the forums to help with various amp issues so thank you!
I have a Fender Hot Rod Deluxe (green pcb) that the previous owner "attempted" to mod using the Fromel electronics kit. The power amp section works fine. So...with the preamp section I have signal going into V1 pin 2 but nothing coming out of pin 1.
Changed tube, no fix. Checked continuity of all components for/around V1 and ribbon cable and everything checks out. So I then checked cathode bypass cap voltages (C1/pin 3) and am getting 0v (schematic calls for 1.72v). Also, the filiments are not lighting in V1 and the tube is cold to the touch. However, I am getting correct 3.3vAC on pins 4/5?
Not sure where to go next with this? Thanks for any help/advice with this!
