Question about Audio Players & Recorders

1 Answer

Hi; I am looking to replace a smoked SVI 3206 B IC that runs in a Technics SA-GX700 Amplified Stereo Receiver Manufactured in the early 1990's. I have not been able to find a replacement. I see SVI 3206 D AND C but no B. I was wondering if someone can help me? Sellers that deal with distrubuters do not have them. This is a amplifier Chip.

    Reply: I do not know Panasonic Suppliers.

    My Electronic Repair Depot said they checked with Panasonic and they just said the Chip was no longer available.

    I looked at a Parts Store site and was looking at that Panasonic parts section shows the parts, but nothing corrisponds to the SVI3206 B. Just the other 2 the C & D. I also need a 6 amp 125Volt horazontial glass fuse to replace the one that blew out when the Chip got fried by what my Electronic Repair man said was most likely a short at the speaker connection at the back of the receiver by moving it around when it was on. He also said that Panasonic revised these receiver amplifiers over the years, so the connections at the back were less likely to short if the receiver was moved while on. He told me to just keep my hopes up, and keep plugging my way around the internet, and i should eventually find something. So that is what I am doing, because these new receivers I do not like the sound quality at all. They are simply to complicated to run, and sound like a tin plated ash can. Thanks for your help so far, and I will let you know how I make out in my quest.

    I found someone that had 1 and I purchased it today. I should receive it in a week or so. Good thing I am a good desolderer and soldierer. Looks like 13pins to deal with. At least there is only one side.

    A Electronic Shop gave me 2 fuses for it free, because they said it is not worth the paperwork when there that cheap. I was wondering if there may be any surprises I should be aware of before I start the repair? Thanks.

    Yes I will go over the boards with a fine tooth comb when I take it apart. The Repair Depot did not mention of any internal shorts. They told me that they thought it was caused by a short from outside the Receiver. Someware possibly corrosion at the speaker plug, for which they might have been right, because I found one of the connectors at one of the speakers Rusted, and looked heavily pinched within the connectors part that holds the centre wire going through the connector. I already changed that connector in preperation for the resumption of using it. I will let you know how I make out after I receive the Chip in about 7-10 days. Thanks for the info. Jeff...

I seem to recall that the C and D variants are direct replacements. Check with an authorized Panasonic parts supplier. Check with local service shops for SVI3205 as well. All of these are interchangeable.

    I have checked this further and yes, all variants of this IC are no longer available. However, check with some local shops that work on audio gear, they may have one lying around. I know that I still have a few in my shop. These were often purchased in groups of 2 or more, so there may be a few around still.

    You can also look for SVI3205 and its variants as well.


  • ABRsvcs Sep 10, 2010

    The letter variants should work just fine. If I read your comment correctly, you found the "C and D" varitants. Those are pin compatible and should work just fine.


  • ABRsvcs Sep 10, 2010

    Verify that the solder connections for the IC are all good. Check the solder connections at teh voltage regulators as well. It is possible that poor solder connections at the regulators can cause failure as well. The fact that the fuse was blown sugests that the IC has shorted internally, but you can't tell easiily. Be extra careful of solder splashes too.

If these are model numbers,you would need the part number of the IC. If the IC is specific to Technics, it is most likely to be unavailable. If you would like more information, or would like to inquire about a repair, please visit my website at You may contact me there. Thank you.

I am trying to locate a replacement SVI 3023 IC, as used in Technics SA-R230L Tuner/Amplifier. Thanks, Dave.

The SVI3203 is no longer available. If you can find an SVI3205 (it too is no longer available), you can substitute. Where are you located?

Technics SA DA20

I have a Technics SA DA20 control receiver. I was given it by an electronics workshop and it has this same error of OVERLOAD coming into the display when switched on. I removed the plates from underneath and re-soldered as far as I could all the points along the stereo amplifier ICs and as far as access would allow. The unit then worked normally for several hours. I was very pleased, and went out shopping!. But on my return after it had been off for about an hour, the same problem has come back. But my boss at the electornics workshop thinks it it just a dry joint, or series of dry joints. The unit is complex to dismantle, so patience and care is required in taking it apart and making a note or diagram of how it comes to pieces and how to re-assemble it after the board has been re-soldered. It does not appear to be a component problem or fault with the SVI power amplifier ICs.
