Input fuse blows on switch on


In most power supplies, if the input fuse blows that fast it's because of some shorted component right at the AC input. Check for shorted rectifier diodes and filter capacitors. Both are common failures, especially if the equipment has been subjected to power line surges. If the power supply checks out OK, shorted output devices in the amplifier section is the next most likely cause. Check for low resistance on the outputs of the power supply. It's helpful to have a schematic diagram of the receiver for troubleshooting, and you can often service manuals or other information free or at reasonable prices on the Internet.

Modify frequency on a T4A shure reciever


It is not an easy task. First, the crystal needs to be replaced, and possible 6-8 other components that surround the crystal. Then, the rest of the circuitry needs to be retuned for it to operate correctly.

There is a place in Chicago called Delta Audio (773-764-3634) that has the equipment to do this.

Modify frequency on a T4A shure reciever


Hi,

The T-4 has fixed frequencies, the only way that maybe could work is to send it to your distribution centre.

I have a relatively new (less than 3 months old) Harmon Kardon Receiver HK3490. It turns on but immediately turns off. You can hear a clicking sound like a breaker is disengaging. The problem started...


It is a relay clicking. You will need to obtain a schematic to troubleshoot this but they are available online. The protection circuits have been degraded from the short circuit but it is still alive and the discrete components are easy to replace. I used to use Sam's Fotofax but googling your HK model will get you alot of results. Harmon Kardon is a great brand and definitely worth fixing. ~Steve Medley

Have a nearly 30-year old Akai stereo receiver AA-R30. Power light just stopped turning on. Opened up case and found main fuse between AC power cord and power transformer blown. When I replace the fuse,...


Look for shorted output transistors or possibly shorted rectifier diodes. An immediate fuse blowing up usually means that the power supply is the problem. Keep us posted.

Pyramid 14G power supply


Hi.
It very unlikely the voltage went down. I think you should re measure what the voltage should be yes it 13 volt is after the bridge you wil get this with dual 6.5 volt ac from the transformer, they don't change voltage unless you have a short at the output, and if you did you will blow the transformer, is your reading from 2 wires or is it three wires, output, the center to the end should be 6.5 and end to end maybe 13.8.
I would need to see the schematic to know what voltage you should be getting.
I wouldn't look on a bat transformer but ether, bad bridge or wireing.

I hope this help's
