F4 power amplifier

[jleaman]

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 ?

Darry,

Thank you for the report on the sound. It will keep us all going.
The amps you made are beautiful in my opinion -and in Zen Mod's I believe! -he's a liar sometimes

The appearance is clearly non-commercial but not amateurish- perfect.
Inside- like a race car engine

[DocLorren]

you are pushing it Manu.
Darry, congratulations, looks like a very well thought out amp. Please comment on trouble/pitfalls during building and of course how much you like them within your system.

 

[Manu]

Yes but with respect.
Dan vecht mijn land, mijn vlakke land.

How about BOTH of you stay on topic and leave this to pm messages, this is way off topic.

I asked a question and you guys hijacked a good thread for this usless talk. STOP IT.!
