My repairer just misplaced the ic for stereo integrated amplifier su-v50 class AA. So please help me with the ic number


A search with Google shows no such number. If this is truly a Class A amplifier, in my experience, there are no output ICs. Even so, unless they process both channels in one IC, there would be a complementory IC on the other channel.

Is audio output (from main ic) is imputed in utc2003 audio amplifier ic?


Is the UTC2003 IC your main IC?
You can't find inputs or output of this IC?
This IC is power Operational Amplifier simply. It has TWO inputs noninverted = pin 1 and inverted = pin 2 and ONE output = pin 4. Pin 3 is ground and pin 5 is supply voltage. It's simple as the rake! What is your problem? Sorry for my rusty English...

Do you have ic for this brand?


The IC may be available through a source like Digikey if it is not propprietary to the amplifier.

If it is proprietary to the amplifier, a site like encompassparts.com may have it.

Otherwise you may need to search on Ebay for the part(s).

No audio output. muffled output from Phones jack


you need to check the power supply of the amplifier with the help of a voltmeter. if that is OK the power amplifier IC(integrated circuit) is gone bad, see for overheating of IC.

I would lke to know the reference code on the audio out put ic, used in the VHF MARINE IC-M302.


Quick description as per ICOM Manuals:
Quote
The AF amplifier circuit amplifies the detected signals to drive a speaker. The AF circuit includes an AF mute circuit for the squelch. AF signals from IC1 (pin 9) are applied to the de-emphasis circuit (R61, C89). The de-emphasis circuit is an integrated circuit with frequency characteristic of –6 dB/octave. The integrated signals pass through the high-pass filter (Q5, R62–R67, C90, C91) to suppress unwanted lower noise signals. The filtered signals are applied to the AF mute circuit (IC7B), and then passes through the [VOLUME] control (VR board; R1) via the “VOL1” signal. The signals are applied to the AF power amplifier (IC6, pin 1). The output signal from IC6 (pin4) drives the internal (external) speaker.
Unquote
I thus assume the IC you are looking for is the IC described as IC 6.
Data sheet availible online: http://www.datasheetcatalog.org/datasheet/sanyo/ds_pdf_e/LA4425A.pdf
The IC is a Sanyo LA4425A. A 5W Power amplifier.

Only get sound out of right side both a and b


Good day sir, Hi, your Philips receiver trouble can be any of the ff:
  1. your receiver left fuse is blown, check if it has a user fuse at the back. or
  2. your main IC amplifier for the left channel is bad. you need to replace that IC, but check first the wiring of the speakers.
  3. Check your receiver left speakers if it is producing a soft hum, to do this turn down the right channel, or adjusting the balance knob to the left, or simply remove the speaker connection of the right channel. place your ears on the left speaker as you adjust the volume up and down, do you hear a soft hum that goes up and down also? If yes the problem is on the source section before main amplification, usually the pre-amplifier stage, If you hear no hum at all. problem with the main left amplifier. The main amplifier is usually a single IC for both left and right channel, OR one IC amplifier for the left and one for the right, in both cases, replace the bad IC.
