Question about Audio Players & Recorders

2 Answers

I have a Realistic STA-2100 home receiver that quit working. I bought the amp new in 1978. The other day I was listening to music on low volume when it just popped through the speakers and quit working, everything was dead. The 8 amp 125 volt fuse on the back was blown so I replaced the fuse, plugged it in and turned it on. The amp has a soft start circuit that is illuminated in red on the power button and then turns green when amplifiers are switched on but the power button just stays red because the relay never clicks. Where or how could I get this fixed? Thanks, Jon

Tandy Consumer Services (Radio Shack's repair shop) can fix it for you. You can ask for an estimate first, so you'll have a good idea of the repair costs. I have one of these units myself, and I used to work for Tandy. They have all of the schematics and parts that they'll need to repair it. You could probably have it done for less than $200.

That old 2100 is a great receiver, but, there are many things that could blow the fuse.

Your biggest problem is age. The capacitors dry out, transistors deteriorate with age and heating/cooling. The power supply board in the unit works very hard and I am amazed it's lasted this long without repair.

This is a decision on whether or not you want to spend some major cash restoring it or not. There is no point in just going in and fixing the problem, because you will have many more age related problems very shortly. Thats the curse of well build old gear. It lasts well beyond its expected life, to the point where the only sure repair is either total replacement ( new unit ) or total refurbishment ( yank out the all the old parts and renew the whole thing ). I would suggest a repair shop that specializes in restoration.....and your cell phone set on 911 speed dial for the final bill !!...good luck...Rob

Hi having problem with my sta-2080 realistic receiver have equalizer and tape deck all realistic the volume on the receiver goes load and then soft with a lot of cracking sound the tape deck works good...

Is it just with the EQ (or any other single component) in the link? Old equipment develops oxidation on various controls. Depending on physical access, tuner cleaner may help. Or take it to a shop.

Hello Audio Gurus..This is my 1st time on here.. I always loved music and I have decided to raise the bar a little in terms of sound considering that I enjoy listening to music more then 2 hrs a day.. I...

No, the CV speakers are very efficient speakers. That means they create a lot of volume for the amount of power. I will start by saying you will be relatively happy but not blown away.

The HK is an alright HT receiver (very new and feature loaded). It makes a rather weak stereo receiver for it is made for a home theater environment. If you only have a pair of speakers (optimal for music listening) then you have paid for a bunch of other channels that will remain dormant. You would be best off to get a very high-power stereo receiver or integrated amp instead of your HK.

CV speakers are built to blast, but they sounds pretty good at the same time.

Feel free to ask me any audio related question, I've worked in the industry for a good part of my life.

I have a realistic sta-2600 ,no sound from one channel any suggestions? volume knob maybe?

This model is notorious for cold solder joints. Chances are it needs some touch-up soldering.
