SOURCE: problems with amp switch

get an ohm meter and test to a known ground, like the sleeve on the guitar cable. If neither is grounded, it doesn't matter. If one is grounded, take it to neutral.
Best bet, get the same switch and put it in exactly like the one you have.

SOURCE: Samson MDR8 blowing internal power supply fuses.

Here is a troubleshooting hint:

Put an incandescent lamp in series with the hot side of the power cord. This acts as a resetable fuse while troubleshooting so you don't blow fuses.

Schematics are hard to come by, but power supplies are easy to trace the circuitry.

Check filter caps and the diodes and THEN look for hot (temp) IC's and transistors.

Peavey XR8600 can't get it to come apart


And why would equipment blow a fuse the minute you turn it on? Well, I would say because it's defective. Bad power supplies, burnt components, shorted diodes and/or transistors or dead IC's. It's repair shop time bud and make sure that shorted speaker wires or defective speakers didn't damage it, as reconnecting a freshly repaired unit to the same wires/speakers could damage the unit twice.

Is the fuse good? Check the fuse for continuity as I have had some fail that were not obvious.

If the fuse is good- the power switch may be suspect. unplug it- short the leads on the switch- depending on the switch you have, if you have 2 wires in 2 rows- it is a double pole switch- short the wire below to the wire above on the same side of the switch, and then plug in the amp- it come on. If it does- the switch needs replacement. If it does not the power supply needs to be checked over.

TH-15A won't make sound. Comes on, then flashing front light


This probably means there is a failure and the internal protection circuits have activated. It will probably have to go to a shop for repair.

Is a sustain foot pedal similar to a tattoo machine pedal?


The sustain pedals have only two wires. Usually they terminate in a 1/4 inch mono plug.

yamaha USUALLY sustains when switch is closed. Roland usually sustains on a switch between the wires when the switch is open.

NO POWER should be supplied BY the sustain pedal... it is ONLY a switch.

Power Supply V-amp 2 Pinout Diagram


Don't have the pin lay out but the power supply is a transformer with two isolated secondaries. The blue & brown leads come from the 20VAC 200mA and the black & white 11VAC @ 800mA windings. I used two doorbell transformers (and a rheostat for the 11VAC section). The reason for two transformers is the secondaries MUST be isolated or something will fry!fb818bb.jpg
