Just pull the installed fuse out and look at the voltage printed on the side of it if that information isn't already printed by the fuse holder. Should be 110-120 volt. Just make sure it's not a slo-blo or some other type

Dust in the unit - clean with Canned air like a computer.

or Delamination on the printed circuit board.
Don't forget to clean all contacts on the backside of the unit!


If cleaning doesn't work - head to the local Crest "AUTHORIZED" Service Center.

You could use the EQ but it won;t sound as good as it will with a pre amp and also could make it a bit trickier when adjusting the volume and getting it to sound right.

Hi E:
You directed this question at me, but unfortunately this isn't my expertise and I am unable to provide you with a real solution at this time.

Hopefully one of other experts will be able to provide you with a real solution.

Thank you for using FixYa.

The pre amp. inside the amp. is burned. A local shop can most likely fix it for about 100.00.

usually, crackling is due to 3 things:

1) the soundcard (or sound device you have them plugged into)
The best way to test this is to plug in another set of speakers or a headset directly to the sound
device, and listen. if you don;t hear the crackling, than consider that idea scrapped.

2.) speaker wiring/cables. Check the wiring for cracks/frayed spots. Do you get any crackling during/after you move the wires? if there is ANY change, for the better or the worse, than you have your culprit.

3.) the speakers themselves. when the first two options above are exhausted, there's only the insides of the speakers themselves to blame. you might not have seen any cone deterioration- but other things could happen, such as deteriorating wiring, etc.

for new speakers, they are relatively cheap- Here in Canada at least, I can get a new 2.1 set for anywhere from $25-60. Although, I'd strongly recommend any of the Logitech brand speakers- most models have subwoofers with unbelievable bass (for the price) through them. I myself have the more expensive Z-5500 series from them (5.1), and I've been more than impressed.

indeed chaffburner you are not the only one with this problem. over 93% of my searches result in the "monster cable" version of this product. even the RCA site did not have this manual (and the product is just over 5 years old). if anyone out there knows of the whereabouts of the elusive RCA HTS 2600 Home Theater System manual ---in any form--- please drop a line. i'll be happy to pass it along to chaffburner and the other sites that deal with user manual searches. thank you for your energy.

Record players are broadly divided into three groups with the vast majority being either belt drive or the classic drive of a rubber-tyred idler wheel running on the inside of the outer circumference of the platter.
A few are direct drive...

The belt of the belt drive type is the most troublesome due to age affecting the elastic quality of the belt material.
The classic drive is troublesome over the longer period as age hardens the rubber tyre and removes it's natural friction.

The few high quality direct drive types have a small degree of speed adjustment and the correct speed is checked by a stroboscope. In the case of problems with this type the help of a specialist will be needed.
Other drive types exist but are very few and far behind.
