I know that there is already some threads running on this subject but I have a small question not mentioned anywhere about the caps required for the power supply.
I own a Monster that was bought many years ago from Holland and it has original components on the PCB
.
At that time I was not into diy that much and even less about the electronics behind things even though I have a Master in engineering. I know my physics and some electronics but had not devoted myself into building things at that time.
Ok, problem is that I had a minor accident with the amp, cause when shipped to Sweden the capacitors had been falling from their position (glued to the bottom of the case and no other support) and I, happy for my new Monster, couldn't wait to "fire" it up so due to contact between chassi and capacitor bank I had a small "fire" and some capacitors where destroyed.
Some time after this accident I met a person who said he could fix this and so he did..... by his own head and got it working but not accordingly to the original set up (the amp that I bought was not having a correct power supply either). The amp is working but I have some hum and also some undefined cracking sounds so I have now decided to do a real check up since I have starded doing my home work about electronics. The cracking sound I have isolated to bad contact somewhere in the power supply but the hum I am absolutely shure is because of the bad construction of the existing power supply.
My idea is to build the power supply accordingly to the picture below
Now my question is, the batteries are parallelled with amongst others, a supercap 0.47 F but what voltage should be choosen??
I presume I should at least have 12 V (since I am parallelling 12 V batteries) but that is getting tricky, have problem finding those values.
Any help out there??
