It is both proprietary and obsolete. You might try some audio forums and Ebay. There is a slight chance encompass parts.com may have it.

The IC is/was made by Toshiba.

My sansui tu 217 makes a popping noise and looses all volume when i turn it above 1


Volume controls these days pass signals to an IC that controls most functions such as volume and tone. Following the wiring from the volume control should take you to the this IC which will need to be replaced.

Sansui sv2918 keeps blowing k2996 mosfet. Power led flashes and ta-ta-ta sound is heard


Check the Flyback Transformer

and associated circuits.

If 2SK2996 is blown, it may take out the PWM IC and some components

that goes with it.




Let me know what you find or needs further assistance.

HOW DO I GET THE INTERCOM TO HAVE A TONE ALERT


It's done in programming so the AUTO ANSWER button can control it. It needs to be dark and you need to tell the phone it's a TONE CALL. In a TA series that's done via (without picking up the handset) press PROGRAM 41 STORE. (42 is VOICE CALL and the button becomes the MUTE key).

Now, the AUTO ANS button toggles between ringing on the intercom and Voice Announce with Handsfree Answerback when lit.

Yamaha AX-596 Integrated Amplifier only works when using either of the two "Pure Direct" buttons. The Bass, Treble, & Balance controls do not function. It would appear that circuit board or the circuit...


Chances are that the tone control pre-amp circuit is faulty. These days the functions are all done by a single IC. Find that and you will more than likely have found the culprit. If there are any of the controls for bass etc on the front pannel, trace the wiring back from them. If not have a look around on the PC board in area that you suspect (some boards are marked as 'tone' etc). If you see any IC's put the number into google and you might find out what each does. Keep doing it till you find one that deals with tone etc.

I have sony TA-V715 amplifier, one set of (cd, phono, tape)input-red colour cable input is not working. Please give me a solution.


The possibility is that one of your premap input is not working and the fault could be in the preamp input section. Possible that the input IC, the selector digital IC or the tone amp could be faulty. It will be easier to find as one section is working and you can cross check with voltage readings from teh working side. Also apply the audio test from the output to confirmt he section, replace from the working side to confirm the fault. I hope you have checked on the speakers/ ouputs by crossing.Also check for fuse or failure of the output section. Hope you try and confirm.Good day .

I am not interested in traffic information at all. I want to hear radio without interruption, especialy when I sit at home. How can I prevent traffic information interrupting my radio ?


MostRDS radios can receive short messages which might include informationabout the presenter, station or programme you are listening to. Forexample, BBC Radio 1's RadioTEXT always gives information about thepresenter and programme e.g. JOHN PEEL - TONIGHT IN SESSION.. ETC.., whereas Classic FM gives information which includes a web address for the station, e.g. CLASSIC FM ON THE WEB - WWW.CLASSICFM.COM.The information will usually scroll across the display on a home tuner,but this could be distracting to a driver in a car, so the RadioTEXTmessage in a car hi-fi does not scroll.

Theradio display can show if the station broadcasts travel information.Since most stations do anyway, this feature by itself is of limitedvalue. The Traffic Announcement (TA) feature allows interruption of aCD or cassette tape when there is a travel report from the radiostation that is currently tuned-in. The radio will automatically switchfrom CD or tape to the radio for the duration of the travelannouncement. Commercial radio stations willbroadcast three tones or 'bleeps' before and after the travel bulletin,but BBC radio stations do not need this. These DTMF tones are used whenthe transmitter (where the RDS inserter physically is) is locatedremotely from the studio, and for reasons of cost or practicality thereis no control path from the studio to the transmitter to tell thetransmitter when to switch on the TA flag. The only link from studio totransmitter is the station audio itself. Inthese situations, "in-band signalling" is used. A unit at thetransmitter site listens out for the DTMF tones in order to switch theTA flag on and off. The DTMF tones are recorded on the traffic jinglesto make life easier for the presenter. For the TA feature to work underany circumstances, however, the function marked TA, TI, TP or 'Traffic'must be switched on. It is possible to search out only those stations broadcasting the Traffic Programme on some radios.

How to transfer OS and data to newer Poweredge server


The new RAID controller should read the data from the drives and work without difficulty. You will need to transfer all drives at the same time. Be sure to put the drives in the same spot in the new server.

Here are the bad news parts:

1. Your data is at risk. Make sure you do a good backup before trying this.

2. It is far more likely that your performance problems come from disk access or memory than the actual processor. If this is the case, then you probably won't be helping yourself with the migration. If you haven't already done so, analyze what is causing your performance bottleneck to make sure you are going in the right direction.

I have a working Dell Poweredge 2650 with 2 x Xeon 1.8Gig processors, 5 x 36GB hard disks, running Windows 2003 Server. I have recently purchased a newer Poweredge 2650 with the same configuration except...


You should be able to do this by moving the drives all at once ALL DRIVES MUST BE PLACED IN THE SAME SLOTS 0,1,2,3,4, do not mismatch else it will be a nightmare ............HOWEVER BACKUP your data up if you are going this route,on paper it might sound like a winner,however not all that glitters is gold.controllers though they might be the same have different firmware which allow them to do different things,so if you are going to this the os drive raid 0 or 1 must be two seperate is drives.once this done,how is your raid set up for the other drives once you have a good back up to restore if there is any complication,move the over in the same order,remember POWER DOWN BEFORE YOU ATTEMPT THIS .PS REBUILDING TAKES FOREVER.
GOOD LUCK
