Vibration Technology Ltd. VR140 Guitar Equalizer Amp (Help with repairs)

[bkeeley]

Hello All,

here's the challenge... Vibration Technology Ltd. (VT) Guitar Amp VR-140

Will not power on.

I cannot find any skits, previous owner information, or company information beyond the most basic details.

Can anyone help me get off the ground ?

Is the amp powering on at all? If it has a fuse have you checked it?

[bkeeley]

It is not powering on at all. It is missing a 3A Slo-Blo fuse in the back. I just purchased one, although the fuse cover/cap is missing. I will need to find a cap to secure the fuse. I am worried if I replace the fuse, it will not solve the problem because I assume the fuse blew due to a issue with the power. I will have to test it out.

If you plan on repairing it yourself I would start by making a short check lamp (standard light bulb wired in series) See picture.

Mount the items on a small board and insulate all wiring by using electrical boxes to not be exposed to high voltage/current.

start at a 60 watt buld and if it glows bright you have a short and the troubleshooting fun begins.
