Question about Crate Music
When playing on Channel B, the amp will suddenly go to a very, very low volume that is barely audible. I have looked on the inside of the amp head, and nothing seems to be broken or not attached.

If you can solder, try resoldering any connections on the board that appear grainy or have rings. It is likely that after the unit has been working for a while, the heat is causing a marginal connection to open up.
Keep us posted.

SOURCE: amps broken need to fix it
Their may be a schematic on the inside of the amp.I don't remember if Crate puts one or not. And I have had several Crate amps. never needed repair except for tube replacement. If there is not one in side , go here and find what you need . http://www.crateamps.com/support/warranty/ Good luck DFD please rate me TK U

The symptoms are common to a capacitively coupled signal which is often a bad switch on an insert jack that is bent so as to not contact the signal to pass it to the power amp.
The jacks on MANY of these amps are plain JUNK. If a cable is yanked a bit it can bend the spring contact. When the conttact is very close, but not touching, the capacitance will pass the high frequencies but not the low and ALL frequencies will be very attenuated.

The problem is with the amplifier itself. Crackling is usually capacitor related and you will need to have the amp checked over to properly identify the cause.
Some amps are also prone to pick up static from other electrical items which can also cause these problems. I had a crackling issue with an old Crate amp of mine which turned out it was due to being too near a computer/monitor so it is worth eliminating these things as a possible cause before having the amp checked.
Hope this helps. Thanks for using FixYa.

A possible problem MIGHT be marginal switch contacts on the external foot controller cable. If you are not using the foot pedal, these contacts must maintain contact to keep the same channel selected.
