It's a low watt version.
If the diode a black case , use a 1n4005 or 1n4007
Try measuring the resistor w/ a meter
Let me know if that helps

I have a vox ad100vt 212 it doesn't produce sound what could be the problem


Tube stage in the preamp, give it time to warm up, else could be the 12AX7 tube gone bad, otherwise not worth saving aside from the speaker drivers. Amp and control circuitry were not well made. If new tube does not fix, gut circuitry and install a real amp.

What will cause a 30 amp auto shutdown fuse to blow


Depends what this fuse is for if its for the charging circuit and supplies power to the alternator then 30 amps is too low and this would blow the fuse .You will need to follow the output from this fuse with a continuety meter to see if it is the alternator feed wire which would be the big thick one on the alternator as the output of the alternator will far exceed 30 amp

Hello fixya. So I have placed new pots on a Vox VT30. Tested it and it worked fine. My son was playing while I replaced the back panel. A screw was too long and touched one of the pots. It shorted out...


This might be the schematic for your unit:

Scroll down to the link "Get Manual" to download the PDF file.

I don't see any connection on a pot that could be touched to cause the problem. OFTEN when screws are too long and they touch a board they can crack the circuit traces or PUSH etch to cause a short.

Use a BRIGHT LED flashlight to "candle" the board for cracks or scrapes. The voltage regulators are current limited and self protecting. The first thing is to determine what the screw touched and look for damage in that area.

I hope you replaced the pots with the CORRECT TAPER as well as resistance value. Whille incorrect taper would not inhibit operation, it would make adjusting the pots in use somewhat difficult.

Hi im in Argentina and i accidentally pluged in my amp without an adapter now it doesnt work what needs to be fixd?


The power supply is blown. Argentina is 220V I believe. I have never seen a power supply schematic for this however being that it is low power it is a linear supply not switching. Either the rectifier diodes are blown out or possibly the output capacitors are blow due to approx double voltage. If you try this yourself be careful otherwise get a new amp. Good Luck

Rockford amp cut out


Disconnect all speaker wires from the speaker terminals of the amp and disconnect the RCAs. Replace the 30 amp fuse with a 15 amp fuse. If you turn it on and it blows the fuse, it's likely that it has shorted output transistors. If that's the case, you need to have the amp repaired.

Amp blowing fuses


The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).
