I am not meassuring anything with F4 hooked up, only meassure DC-offset on pumpkin..
that's certainly some gremlin in your room ; you put R27 and R29 in?
This leads me to, not to worry about it so much... As i read between youre lines, that you are supposed to see some pendling with voltages etc... except eg. in total 'clean' condition... which i surely not have done yet, as my case isen't finish.
not between the lines but exactly in them - do not worry at all .
for that type of circ that's completely normal behavior ;
measuring between outputs (before output caps) offset is low right from the cold, but offset between any output and gnd is starting from 1/2 or 1/3 of positive voltage and it's slowly decreasing during warm up .
that's why caps are there ; purist will certainly think about implementing even input caps....... not me
.........well i can also tell from sonic, that's its not all wrong
I hope ..............

Wrong ??????????????????????
I have R27/R29 on my circuit ! In fact my pcb's are made excatly from schematic...
EDIT: F4 also made as schematics.
EDIT EDIT : C13 / C14 on your'e nice pcb's arent on schematic... extra voltage regulation cap's. ?

tiny difference ........... who cares about that?

Beware !
Remember :
Is it right / wrong ???that's certainly some gremlin in your room ; you put R27 and R29 in?

And today's listning goes on right now... had to goto party soon
play's near 110dB i guess right now... had to run now seya'...

just relax .......... everything is fine .
specimens for Burning Amp Fest
so- I promised to AR2 that I'l send him for Burning F4 and what else.......
unfortunately - from objective reasons reg pcbs are not finished yet , so Mr. AR2 will receive just 1/3 of ......... entire story is really complete only with those regs .
anyway , few pics right from the bench, without special lighting ; I am just too tired to arrange proper light ......
