Just acquired a beautiful-condition Sherwood SEL-300 tuner and SEL-400 integrated amp. While the tuner is fine, the 400 powers up without turning it on! Checked with headphones, and all you get is static and a faint signal through all incoming channels - and a loud hum. Have not and will not test with speakers until issue addressed. The unit appears to have not been tampered with, fixed, etc. I'm no expert, but no dummy with vintage gear, either, and have never seen this problem before. Anyone have any insight?

Hello, there is a problem with the power factor of the air conditioning unit and/or the power supplies of your audio equipment.
Read this first... http://en.wikipedia.org/wiki/Power_factor
As you see, the electric motor of the external unit of your Air Conditioning, produces a distortion in the line of voltage, then you must talk with a specialist in that topic....

You seem to be looking for an amp made for car audio. There are many brands, but I going to give you the specs for your particular speaker which will help in choosing, not a specific name brand amp, but at least one with the proper power outputs/requirements.
Your speaker, based on the model number you provided, is rated at 4 ohms .Power handling range is 50-300 watts. And a peak of 600watts. That does not mean start cranking 600watts thru the speaker, it will blow. I suggest you acquire a single (mono) channel amp that provides 350-400 watts at 4 ohms.
Wow, i just answered a similar question so, pretty much the same answer.......

Your speaker,
based on the model number you provided, is rated at 4 ohms .Nominal power
handling range is 300 watts. And a peak of 600watts. That does not
mean start cranking 600 watts thru the speaker, it will blow. I suggest
you acquire a single (mono) channel amp that provides 350-400 watts at 4
ohms. Leaves you a little headroom on the amp, but use caution.
AUDIO gear usually does this when there is a major fault in the power amp section. Unless you are a qualified repair tech, you should have it repaired by a service tech.
Check the speaker wiring in the back. Make sure it is not wired improperly.
You could remove the speaker wiring from the back of the amp and see if it still shuts off after turning it on.
If it still shuts off after the wiring is removed, it is a problem with the amp itself.
If it remains on after the wiring is removed, then I'd say you have a problem with the speaker wiring or the speakers themselves. It still could be a problem with the amp in this case though... just a problem when it is trying to put power to the speakers.
start with the tuner, hook up the equalizer to the tuner, then on the rear of the equilizer hook up all the peripherals except the amps which will go to the tuner outputs and all will feed thru the tuner to the amps and out to the speakers
Hi,
First of all please check the conditions but as far as i understand the conditions the program would be like this-
#include<stdio.h>
#include<conio.h>
void main()
{
int salary,bonus,totalsalary,hours;
printf("enter salary");
scanf("%d",&salary);
printf("enter hours");
scanf("%d",&hours);
if(hours<45 && hours>=40)
{
bonus=500;
}
else
{
if(hours<40 && hours>=35)
{
bonus=300;
}
else
{
if(hours<=30 && hours>20)
{
bonus=150;
}
else
{
bonus=0;
}
}
}
totalsalary=salary+bonus;
printf("Salary=%d",salary);
printf("Bonus=%d",bonus);
printf("Total Salary=%d",totalsalary);
getch();
}
But the conditiosn given by you are not seems to be correct.Just correct the conditions value if wrong and run the program
Thanks!
