Would changing capacitors C1 C2 C3 C4 from 220uf to 1500uf cause any harm on the F4 power amplifier ?

Hello,

I just finished the construction of a pair of F4 amplifier.

See pictures

I use them in Balanced Mono Connections (see synoptic page 9 of the service manual) to have 100 watts output into an 8 ohm load

To listen, I think that it is the best amplifier that I built.

Thank you very much to M. Nelson Pass for the publication of these schematics and its help.

I am also working on my chassis, i got my heat sinks last year and now i can use them. Can any one answer my question about using 1500uf caps instead of the 220uf ones ?
