Amplifiers contain voltages high enough to Kill you even
after the amp has been powered Off !!! If you don't have
enough electronic experience to identify and discharge the
Filter Capacitors which contain these Deadly voltages,
take your amp to a Qualified tech. If you don't know a
qualified tech in your area, post a request in the alt.guitar.
amps newsgroup, the folks there will be happy to help you.
1. If it's the rhythm channel, snip out C3.
2. If it's the lead channel, change C7 from a .002
uf to a .022 uf.
3. If it's BOTH channels, try putting a higher value cap
across R47 to unbrighten "both" channels.
