To me it looks like there 's no input cap, just an output one. Those small blue square things look like local decoupling PSU caps?

Maybe my eyes are deceiving me...

ya remember that all roads goes/leads to Rome ......... or - that's milion and one way to skin the cat

so - there is just no need to guess exactexactexact topology ......

besides that - you know that Papa must make it foolproof , because he sells them ......

Gee-Zus Bruce almighty,

you can see a clear as crystal trace running from the big foil cap to the output hotline.

(and to think that some glare types have the nerve to call moi a blind mole bug-ger)

Thank you Mr. Pass. Photo explain it all


Could the 10 uF output caps be replaced if the power amplifier has input cap?

yup

Looks far too complicated and messy for my liking

Are all those components really necessary?

on a more serious note - the pcb looks like it was milled because of all those straight lines. Is this a prototype board?

Very cool.


P.S. I really dig the First Watt font. It's very Led Zeppelin / Rune-ish.

I just love this forum and the participants here.

Within an hour or two members started reverse engineering the B1 from Nelson's acute angled picture. The forum will have self-documented the DIY article before Nelson publishes it.

Prediction:

Choky will have a complete circuit and boards with customized improvements made shortly called the BBF (Best B1 First), or ABC Pre for "Another B1 from Choky" or something!

People here are simply great! Cannot wait for the upcoming BurningAmp in October again.

tnx for nice words , but I think that I'll be missed this year too , except in case that I find some unexpected funds .....

anyway - do not worry - I'll do everything I can on two fronts :

1 . I'll hate ya all in these days (same as first time )
2.I'll do everything I can to rise my overall financial situation in next period , so my presence on BAF No.3 should enormously rise overall importance of Festival .....



(ps . if nothing else - I'll try to send Brunhilde to AR2 , for presentation )
