@corteng Hey mate,
Welcome to the parasound family ! So, I'm curently not very much in my house and trying to move in another place urgently. I did not have any schematic with me. Opening the amp is not quite possible right now :x
Did you already take a look inside the beast ? First thing is to identify your board number, the instructions I received from Parasound were litteraly a mere word file with the instructions I quoted last year 😂
However if you have basic knowledge in the field that should do it right. Since I cannot really open my amp in the coming days, here are my advices
- Open the amp on a large table, sit comfortably and start scouting the main board. There is a jumper cable where you can read JP13 next to the plug on the board, this one should be rewired on JP14 which is very close if I remember.
Then it's all about finding the P5 and P6 plugs, and plugging on it the white and yellow cable respectively.
Then you need to change the fuse which you can order on ebay easily.
Take your time, don't rush anything yet. Take pictures and post them here if you are unsure !
One great thing at the time I built and still use whenever I'm not sure about my wiring, is a powerful filament lightbulb in serie to your device. The idea is that as long as the filament is cold, it has a very low resistance. Hence, if everything is normal in your wiring, your device will be powered and the lamp should remain off. It is important to use a lamp that requires much more power than the device you want to protect. For the A21 I bought a 500W filament lamp.
If there is a default on your circuit, the power lightbulb will take on the charge and avoid frying your circuit. You'll notice it gets bright instantly, meaning you have done something wrong.
Here is a link explaining it, in french, in case you'd want to do that with more details.
Cheers and good luck mate !
