Hey guys, Can this amp be fixed?

the only thing that looks bad is the cap...as you can see in the pics.

Thx for any help.

Yes, it can be fixed. Cap could have failed because of the age so you only have to change that.

what was the amp doing with this problem? was it immiediatly blowing the fuses or not powering on at all?

just curious........

Thx for the replys guys.... it would power up no problem but it would just make a weird noise almost like a camera shutter coming from the speakers

Hey where can i get one of thoes caps?

is it as easy as removing that one and soldering a new one to the terminals?

Thx.

I suggest getting it from this site.

Make sure the cap you get has the same voltage,capacitance,ESR, ect..

Here are the numbers on the cap.. 330uf 63V....0114T and (M) 105 celsius



what do the different numbers mean? which ones are voltage,capacitance,ESR?

Thx

105C, 63V, 330uf. Thats the cap you need. I think the other is a RF reference number. You can try to search by it, or go by the other info when looking for a replacement.

If it is only the cap then you will be lucky. Those are input filtering caps. In order to change them you will have to remove the complete PC board from the heat sink including the rows of transistors on their thermal subassembly. Not a big job. You will need also to buy the white heatsink compound under the transistors for reasembling. The cap will cost very little actually and something +/- 10% will work fine.
But, you will be luck if it is only the caps. If any of the switching power supply or amp output transistors is blown you will have difficulty unsoldering and resoldering them to the thermal subassembly. I did it on a RF 600A5 and it is not easy cause you have to heat up a huge chunk of copper plated creamic to melt solder but not destroy the transistor or melt solder on the adjacent transistors.

Good Luck!
