Question about Carver Amplifiers & Preamps
Was giver this amp, of course it is used. Was told that it was in working condition. But when power is turn on, amp blows fuse.
Also I have no manual for it.......
First off....you didn't say if you are a tech or not. I'll make this really simple.
If you are not a seasoned tech with experience solving carver problems....you will waste tons of time and money guessing what the problem might be.
Carvers are quite the unique beast. They deliver whopping amounts of power in a small chassis. This is done by using a trick switching power supply. There can be any number of possible problems.
To properly diagnose this you will need an oscilloscope, signal generator, variac, and of course a really good quality multimeter that can test diodes and transistors.
IF and only IF you are a seasoned tech with all the above equipment, that has no experience repairing carver, then go online to ebay, find member techman777, and for around $15 you can get a nicely reprinted service manual. Troubleshooting expertise and the manual will take you foreward from there because the manual has a very thorough troubleshooting guide in it.
If you think you can fudge your way through the guide without any serious electronics knowledge, you are in for a rude shock as you will find that you are an earth man trying to read martian.
If you are just a casual fix it guy ( nothing wrong with that !!! ), I strongly suggest that you do NOT make this your first try at fixing an amp.
The value of these, in mint condition, all rebuilt is around $350- $450 on ebay all day long. if you are willing to invest that much, you can look up carver audio repair on google and send it off to them, as they are reported to do a nice job. OR....you can look me up on ebay, send it to me and I will do a nice job too, and that comes from 20+ years of repairing.
I know that this isn't much help, but carvers are very special, and require special knowledge to repair.
Best of luck.....Rob
