SOURCE: Have an RS- 939 Fisher stereo receiver that will not power on but have power to it.

Could be an open internal fuse or power supply failure

How many watts per channel in a technical pro 1500 reciever?


Is that the RX113, or some other? The 1500 is informative, being peak power total. This is about 375 Watts/channel RMS, which is enough to blast the neighbours anytme.

How many total watts does this system have


Well... It consumes 240 watts of electrical power total so take the audio power specifications with a huge grain of salt, as no audio device puts out in audio power anywhere near what it consumes in electrical power. Heat produced is power consumed, too and nothing is 100% efficient.

In the specs below the only information useful for comparison is in the line I highlighted with >>> <<<<'s as it conforms the closest to the industry standard practice of using:

"X watts into 8 ohms (standard load) from 20 - 20000 hz plus or minus Y db at no more than .0Z% distortion"

The better amps specify vanishingly low distortion specs (0.0x% vs 0.x%) at the cost of being able to claim higher wattage. But they guarantee cleaner sound at the claimed levels.

JVC is being tricky with their choice of a 40 hz lower limit. THAT is the power hungry end of the spectrum. 20 hz is normally the lower limit stated.

"Output Power .............At Stereo operation
Front channels .............55 watts per channel, min. RMS, driven into 4 ohms at 1 kHz, with no more than 0.9 % total harmonic distortion. (IEC268-3/DIN) 30 watts per channel, min. RMS, driven into 8 ohms at 1 kHz, with no more than 0.9 % total harmonic distortion. (IEC268-3/DIN)

>>>>> 30 watts per channel, min. RMS, driven into 8 ohms, 40 Hz to 20 kHz, with no more than 0.8 % total harmonic distortion. <<<<<

At Surround operation
Front channels .............50 watts per channel, min. RMS, driven into 8 ohms at 1 kHz, with no more than 0.8 % total harmonic distortion.

Center channel .............50 watts, min. RMS, driven into 8 ohms at 1 kHz, with no more than 0.8 % total harmonic distortion.

Rear channel .................50 watts, min. RMS, driven into 8 ohms at 1kHz, with no more than 0.8 % total harmonic distortion."

Whats the difference


a digital tuner has one advantage only,the stations can be pre -set.
a digital reciever uses a pll synsethizer to generate a signal to lock on the station,an analog tuner is subject to more drift,and as well the sensitivity is a hair less,but if you get a tuner with fet front end transistors,it will sound better.
alot of people say that the hysterisis signal is more evident on a digital tuner.
buy an old marantz or pioneer from the 70s.
the marantz 2275 is 75 watts a side and will outdo todays 500 watt home theatre amps.
they do not build them like that anymore.

Hooking up surround sound


to get the digital you have to have the digital optical line or the coax rca jack digital audio connection from device to stereo reciever to get the dolby digital surround sound to work , otherwise you can only get a virtual surround sound from the reciever( no dolby digital )

Home stereos


Hi this is Compaqowner again NOTE: I know enough about home Stereos,and I am pretty sure to figure out 'power output' you take the total:in this case it takes in 110 watts total devide that by 2 so according to my math that is 55 watts (I guess this AKAI has a 55 watt amplifier) then you take the amplifier output (in his case 55 watts) and devide that by how many channels are being used,so in 5.1 DOLBY mode DVD movie,etc.(power to all 5 speakers) then it's 11 watts per channel,and in 2.1 stereo (power to the subwoofer,front right,and front left speakers only) it jumps up to a little over 18 watts per channel,again,I think?,when you find the answer,please let me know. Thank you for your time. Steve B.
