Jamie,
Breadboarding will only tell you if it works and not the final sound quality you can expect so IMO do it in a chassis. Hammond chassis are quite cheap and easy to work with.
You'll end up with a reasonable amp, however, be prepared to build another as you will learn so much and want so much more that you wil be compelled to do it all over again with upgraded components, wiring and layout.
That's the fun of DIY. So, skip the breadboard and you'll have something to be proud of.
Re. Caps, never did like motor runs and there is so much more out there (Wima, Clarity cap) and yes, I like mixing it up a bit too.
Had the Ultrapath and the DC45 I have now is so much better.
Cheers

You can Ultrapath your DC45 amp but to do it right you will need a much cleaner PS.

Poor advice . Always breadboard ! It's the best way to get the layout right and get a feel for the sound before committing . This applies especially with relation to placement of iron . Amps built directly into a chassis are fine if it's a proven design but a lot more risky if it's a ground-up DIY effort . I rarely get past the breadboard stage , currently I have six completed amps in various stages of development on pieces of wood . If I built every design I came up with into a chassis , I'd be bankrupt and have even less space for amps than I do at present :)

Thanks Al and Smart.
I think it's going to be cigar boxes for me. Four boxes with two PS, and two main amps.
Do you think it's worth the trouble to line the inside of the wood box with aluminum foil?
Jamie
Big speakers and little amps blew my mind!
Think about this !!
You could get chassis for FREE from the local USPS.
They offer a variety of sizes, called " Flat Rate Shipping Boxes ".
Free !!! The only thing better is if they paid you to take them home.
