Question about Audio Players & Recorders
DENON 480r amp..at least 10 years old..but over time the right channel is quieter then the left and i have to use the balance control to correct the image .seemed an intermitent fault at first but now its like it all the time!
seems like a common problem with some denon amps bulit around this time. since it seems it was a common problem..is there a common fix for it? dry joint? replace a component?
i would love a new amp but cant afford it! so out with the screwdriver and soldering iron!
I have't seen this porblem, have you tried changing the source place's R with L and see if the sound have change side. If it did then it's your input signal.
I would first check the board for bad solder connection, but it sound like you have a cpu problem or the main ic's procesor. This can be checked with a scope with the ouput of the pre amp to see if the level or the same, with a mono input signal only. You may also have a section of the ouput stage not working, the pre amp , the stage before the main amp out will tell you all by looking at the signal level's.
II know it's not easy, but you will at one point need a scope, without it you will notice you're just going at it blinfowled. When purchasing a scope, put the money it it, a good scope will cost a min of $2k. I'm usind a teck scope and love it, I've also used a leader and find it just the same and sometine better for under $1k.
I hope this help
