amplifier repair


1968 Telecaster with Marshal MA100C.

The amp belongs to my cousin, who actually got it in a private deal on Craigslist for a PRS SE guitar.  The Reverb doesn’t work so he asked me to take a look at it. I’m no tech, but apparently this is a common issue with this model…one of the wires in the reverb tank gets disconnected.  When I opened the tank up, sure enough, that was the issue.  Now I just have to figure out how to fix it.  the wires are totally insulated, so I am not sure if I can just take the insulation off and solder it…or if the insulation is required (once I remove it it ain’t going back on!)


My 1968 Gibson SG Special,with my cousin’s Marshall MA100C.  He lent this amp to me to see if I could fix it…the reverb is not working.  Apparently this is/was a common issue with these amps.  I did not have the heart to tell him that… 

1) I am not nearly as “handy” as he thinks I am, and 

2) There is a high probability I will go in there looking for the reverb issue and end up irreversibly f*cking up something else completely and irreversibly!
