Question about Technics SA-DA10 Receiver

Power Amp Module

Turned unit over to a guy to fix it sometime ago and he keeps trying. He thought it was the power amp module as well but could only find replacements at $80 each, so he tried removing one side, and replacing it with the center module, trying to sort which might be bad. So far no improvement. He is now tracing signal thru the thing,  Any idea where to get replacement power amp modules for less than $80 each? If I have to replace all three sending it to a landfill might make more sense. Any response will be appreciated.

    I've lost my right and left channel but not total sound loss. The switching relay for those channels, one of five doesn't hold. When I slightly flex the board or tap the relay, it will make contact and I will get a very faint sound. I believe I lost the power module for the front right and left. I ordered a new relay from electronic goldmine as agood measure. I have worked on ab amplifiers before and have replaced power transistors before. When locating the power amp module I am assuming that they are on the heat sink like power transitors on older amps. Just to be frank where are the power mods, what exactly to they look like and what is the part number and where can they be bought? thanks

    i have some kind of problem with this receiver ,is a desing problem,the power module for the channel A is on tha same heathsink with the sorround amp module so they go hot and the heat protection activated and turn off the sound
    if you see at the rear panel,a gan even is hot that don't turned on
    so
    i put a 9vdc (cell phone)power adapter and conected to the fan and the small transformer hooked to the ac terminal of the reciver ,that one on the rear,so when the reciver is turned on the fan start working and now the reciver work ok.

There may be more reasonable prices around but you will need to post the type number of the module.
Unless it is a proprietary part number, it should have 2-3 letters, then several numbers following and perhaps another letter.

These units seem to have more problems than others in their class and they may have inadequate output protection.

Kenwood KR-V999D no sound


Hi there, it sound like a faulty elco. I think in english you call it electronic capacitor. open up the receiver and scan for blown elco's. the have rounded tops most of the time when blown. Check capacity and change accordingly. It should fix it.

This means that there is a short detected on one of the amp outputs. Try disconnecting the speakers from the back of the unit and power on. If fault still persists then likely you have a bad output ic or FET (transistor). If fault goes away after removing speakers then plug them in one by one to see which is the culprit.

Want to use my current speakers with a new surround sound system. Current system is 5.1 channels, rated at 100w per channel @ 8. Ohms. New System is rated 145watts, 5.2 channels at 6 Ohms. Will b ok?


Hi Ronald.
8 Ohm speakers will work just fine as replacements for the
6 ohm speakers. When fitting speakers you need to consider
The power handling capability. The impedance and the frequencies
involved. Power handling is expressed in wattage ie 100W.
Unfortunately this can be expressed in rms, max or peak music. The rms value (root mean square) is the only really relevant figure as this is the continuose handling power at 1 KHz. The impedance
is the resistance that the amp sees but is not a dc resistance and
varies with frequency. The lower the impedance the more power
will be drawn from the amp. In the event of a short circuit across
the speaker the amp will try to deliver infinite power into an infinitly
small load in an infinitesimal amount of time and will self destruct.
Using an 8 Ohm speaker draws less power than a 6 Ohm speaker.
Connecting speakers in parallel; results in the impedance beingreduced. For example two 8 Ohm speakers in parallel will result
in a 4 Ohm impedance load but in series will be 16 Ohms.
Incidentally the the .1 (5.1) is the sub woofer which only has
to handle the bass frequencies, a small percentage of the
amplifiers overall frequency response..
Connect your speakers and then power up the amp last
after double checking there are no shorts on the speaker
cables.
All the very best from Vintie.

Can't get my Kenwood VR715 receiver to go into the Select a speaker system to see if speakers are turned on. Followed manual instructions and can't get in. Any Suggestions.


Try resetting the unit by unplugging the unit from the wall, then plugging it in again WHILST holding the power on/standby button in. This should reset the system. If not:
ELECTREPAIRUSA@ELECTREPAIRUSA or you can contact us at that address as we repair/renovate all items electronic and electrical old and new.

Onkyo 5010 amp. Blue light went out in front and sound stop coming out. I clicked the power button and a click occurs inside the unit like its powering up but still no light or sound coming from amp.


This is either you have something loose as in a connection at the back, or the output transistors/IC are open circuit.

Switch on akai58022 tower speaker, it worked when I got it today and now it wont even switch on


what do you have it plugged-into for power ? it uses the 8-pin Apple Lightning dock connector. If you are using a USB adapter for that, then be aware that a USB-port will only let you draw 500mA or 1/2 an Amp of power....more than that will cause failures and damage to the USB port and the Hub even.

Wailing sound when 1971 seeburg juke box is started


I amnot very familiar with Seeburgs but the trip switch activates at the end of the record playing and THAT mutes the amp. The amp should also be muted until the tone arm lands on the record. So I would suggest the problem is in the amp.
