Greetings Forum Members.
This is my first post in this forum so please excuse me if I accidentally break any of the rules.
Here is the problem: I have a fender champ 600 tube amp that produces a sharp twacking like sound when I play notes within a certain frequency range. There is no sustain to the sound and the volume is very low compared to what the expected output should be for the volume setting on the amp. Also, there is no apparent pitch to the sound, just a dead, soft, twack when I strum any of the higher pitched strings on the mid to upper frets.
I know that tube & speaker failures are common with this type of amp and at this point I have replaced both of the two tubes as well as the speaker with no improvement in the overall situation. I have also checked both the fuses and they appear to be intact. The power light comes on when the power switch is on and both of the tubes appear to glow.
I have visually inspected each of the capacitors and they appear to be in good condition. I have double checked the guitar and cable with another system and they are working fine.
Can anyone give me some advice as to what to check next, and possibly a good methodology for doing so? I am aware of basic amp safety precautions such as high voltage, working with 1 hand only, grounding out caps etc... Any help would be much appreciated.
