If the service manual is not available on the JVC websites then you should just Google search "JVC A-GX3 service manual" There are many websites that archive manuals. You'll probably have to pay for a copy. Why can't you disassemble the unit and see the output transistor numbers first? More importantly how do you know this is the fault?

direct substitutes would be 2SC5198 and 2SA1941, you can pick them up from mcm electronics. or do a search on google for the part numbers to locate a supplier closer to home.

hope this helps,

SOURCE: I do have a Peavey XR500, series 260C amplifier,

I would try looking for 2SJ6357. Japanese transistors tend to drop the 2 when putting the numbers on the parts.

My problem i lost transistors for power for car amplifier audio apache i need numbers for transistors


There might be still other power transistors left, same part number

for the power inverter ( IRLZ43N on some ).


Except for the Main Amp that have Complimentary Pair


check for possible burnt or open resistors , too

One possibility is that the power-on speaker protection delay is stuck on. The most common cause of this is a shorted transistor in one of the power amplifier channels. In that case, you will need to replace the speaker driver transistors in that channel. I don't have service information on your particular model; it may use power amplifier modules rather than individual transistors.

The tricky part is identifying the amplifier power and speaker output terminals to test for this problem. To find a shorted output transistor, you need to measure the resistance between the output of each channel and the plus, then the minus power supply connections. There is a relay between the amplifier output and each speaker terminal on the back; this relay is turned off by the speaker protection circuit, so you can't measure from the speaker terminals. If you have a fried transistor, one of the tests will show a resistance of a fraction of an ohm. A good transistor will have a very high resistance or read open. This will be the case whether you have modular amplifiers or discrete transistors.

If you see a blown fuse, that is a strong indication that you do have a fried transistor. Sometimes the speaker protector circuit shuts down fast enough to save the fuse, but not always.

What is full meaning of the following codes in design and constructing an inverter-NE55,CD4013,JRC455,A733,IRFP150,1N4007,C945.


These numbers are the identification of some electronic devices that probably are being used in the inverter's circuit:

CD4013 - Dual D Flip-Flop integrated circuit
1N4007 - 1 A rectifier diode
IRFP150 - power MOSFET
A733 (2SA722) - PNP silicon transistor (low frequency amplifier)
C945 (2SC945) - NPN silicon transistor (low speed switching)

I could not find the devices marked JRC455 and NE55 - maybe they were not correctly marked, but there are some devices which have similar designations: JRC4559 is a dual operational amplifier integrated circuit and the NE555 is a time/oscillator integrated circuit.

You can download their datasheets from

Hope this information can be useful!

My amplifier fuse was blow when i try to turn on the power.after that i did replace with new fuse and then i try to turn on the power again but the fuse blow again.so what make it happen?can you help me...


You may have shorted output devices in the amplifier output section of the amp circuit...these are usually mounted to the heat sinks and are very large output transistors...if you have an ohmmeter available you can test the outputs...there are 3 leads on each output...you want to test the transistors by putting the ohmmeter in the diode test mode and then put the leads on the transistor to check for a 0 ohm reading..there are 3 leads so you will have to test all 3 in all combinations possible...for example: the 3 leads of a transistor are labled E,B,C...so you want to test E and B, E and C, B and C...if you find a shorted transistor, then you will need to get the part number off the transistor and obtain replacements...you can order replacements at mcmelectronics.com

No Power


Hi...there,
No, power.. Could one things, your backlight inverter are burnt out. Need to replaced a new inverter or repaired it.
