Hi,
The original filter caps used on the Onkyo M-504/M508 used 4 pins with irregular spacing and this part is unobtainable AFAIK.
To my understanding 2 pin caps are fine functionally but they simply cannot be fitted into the original holes. Some folks have found various "hacks" but I'd like to do something more elegant, especially since there are 8 caps and something can go wrong.
I was thinking about making a circular PCB in the diameter of the original cap, where a standard 2-pin can be soldered onto, and it would have 4 pins in the original spacing. In this case 8 PCB's would be used.
Another option is to have a single rectangular PCB, where all 8 caps will be soldered on to. The PCB will can then have pins soldered on the bottom, or attached with standoffs and connected via wires to original locations.
I've never designed a PCB and have no idea where to start.
Is this a good idea? bad idea? Anything else to consider?
Thanks!
