Any difference between radial vs axial caps. Seems like if you want to save space, radial is the way to go. Any anyone have any thoughts. Radials are considerably cheaper. Seems to me in the DC filter circuit all that is required is a good fast cap. Wouldn't it be safe to say that any good quality cap in the filter circuit is fine. Why pay the extra money if you don't have to. With that being said is it safe to say that inexpensive caps for the power circuit is fine, spend your money on high quality caps for the audio circuit?

Any difference between radial vs axial caps.
Radial = 2 legs out 1 side
Axial = 1 leg out 2 sides
Other than that, there's not a significant difference.
Most people probably start off repairing old amps or building clones, and therefore have a tendency to use axials because that's what the original amp used. And since we all generally start off copying the known layout, we tend not to branch out away from that.
If you want to use radials, and the short distance their leads can span is ok in your layout, go for it.

Radials fit printed circuit boards better.
Tag-strip favors axial.
Axial on tags is easier to remove than radial on PCB.
Since "everybody" (except us?) uses PCB, radials are far more common and often cheaper.
Last time I built an amp, I dog-kenneled six big radials for the power supply, but axial on the amplifier tagboard. (Fender conventional dog-house may not radial so easily.)
