    JVC AX-435 vs Yamaha AX-470

    I'm trying to decide which among these two amps is better. The JVC is part of the Super-A series, so I know that it's a Class-A amplifier. On the other hand, I cannot find much info regarding the Yamaha. In your opinion which is the better amp?

    Hi, I'm looking for opinions regarding these two amps. I already own the Sony STR-6120, but it recently stopped working (probably due to a burnt transistor). I don't have the skills to repair it, so I was thinking of eventually giving it to a professional down the line to fix it. Since the...

    JVC Receiver powers up and comes out of protection, but I have 12 VDC backfeeding out of the RCA inputs.....

    Hello all, have not posted in a while. I recently picked up a JVC L-FX22 DD Turntable. Everything on it works great except the auto reject. The tone arm needs to go all the way to the spindle before it rejects. Also it is a little jumpy rejecting which i blame the old grease. I have searched...

    JVC AX-R97: Fuses Blowing after changing burned resistors

    I changed out the resistors on the spreadsheet, and now im blowing fuses. I know I used the ones to spec from the service manual, so now I'm not sure what to do. I believe R803 may be the culprit for some reason, but I'm not sure how to proceed. Any advice would be appreciated.
