Question about HP Televison & Video
Hey, The right channel on my Sherwood ax 3030r has given out, occasionally it will kick in once I try re-connecting my speakers, However it never lasts long. I was curious if this is something I can fix at home, being dust or maybe a minor electrical problem with a connection?

Hi There DEKCAT
Its very unusual for both channels to blow......
I suspect that there is a blown power fuse inside the case......
There are fuses sometime located on the outside rear of the case and these can be easily checked to determine if they are blown..If you find one is blown please replace with the corrrect rated fuse,..... its current rating wil be on a small label on the case outside rear. like 1.0amp, or 1.5amp etc...
If you need to go inside the case please ensure the power plug is removed from the wall socket first.
You will find small glass fuses in the DC power supply feeds and probably one of these has blown, once again replace with the correct rated fuse.
Im not sure if your amplifier is a FET type or a large 32-40 pin IC type as if these are blown you will need a service person to do the replacement...
Please note there is a small relay that clicks 20seconds after turn on at the switch....if this click is not happening then there is problems with the timer circuit or the relay itself...
This relay controls the output to the speakers and as such stops all the sound output if its not working...so the first thing is to check all fuses, if they are OK then check the Relay operations....
Cheers From YUBEUT

The problem is the fact that the new receiver has no phono input. The phono input has an extra stage of amplification built in. Your receiver is working fine. You need to purchase a phono pre-amp. These run around $20. Connect the turntable to the preamp and the presmp output to any line level input on your new receiver and everything will work as expected.

Yes you can use either A or B without a problem. The restriction is when you have both A & B connected. In that case, the speakers MUST be a minimum of 8 Ohm impedence. Using either A or B, you can use speakers of 4 Ohms impedence.
