Yes, they'd be fine and as Techmman says, do them one at a time to see what, if any, improvement it makes in reducing the hum. Just to clarify, those aren't 'radial' they're 'axial'. 'Axial' caps are when one wire comes out of each end - 'radial' are where both leads come out at one end.
If you look at the pic you posted, you'll see that there is a ground tag near to the base of the cap which looks unused. You could if you wish, use that solder tag to anchor the negative ends of the three caps, with the individual positive ends going to each of the three red wires. (Insulate the joints with sleeving). Not to complicate matters, but you may find that the three red wires go to nearby solder tags, so if the new caps will reach from those tags to ground, you could just unsolder the red wires completely and fit the individual three new caps between those tags and ground.
Just make sure that you know what you're doing, and if need be, take before and after pics. Always 'do a bit - test a bit' - don't change several components at once on this or any other set or you'll get into a muddle. Look at the circuit and try to relate it to the component layout so you understand what you're doing - not making a leap in the dark.
Hope that helps. |
David i am going with your plan .If i can reach the red wire contact location then i can remove the red wire altogether . That way no joints . Nice one David .
Thank you for your help David , your still with me helping me along .I will let you know when i have one cap in place . Replacing then one at a time as i go .I will do one first then if no change reconect and do the next one.
