One on the output watching DC offset, one across the N source resistor, the third on the P source resistor.
All three need to be monitored as you adjust the two pots. It’s all one big DC balancing act.

for us Cheapskates, these 2 are enough, clipped in appropriate places in circ
3rd one as free shooter, for whatever grabbing my attention
Same as Papa's Kung is Funniest Fu, his gigglywiggly pics are worth at least 2 thousand words, each
That's for us Sissies, to bang on keyboard, asking for specs, instead of looking at (reposted) gigglywigglies
Go slow while watching the meters and it helps to know ahead which direction raises/lowers current. I was at first a little cavalier biasing my F5 and somehow popped a JFET. If you have to buy $$ replacements, as I did, you won't let that happen again.
Correct me if I am mistaken, as the bias goes up, at least to w/in spec, temp goes up, distortion goes down and as temp goes up bias will increase. Is this a function of resistance lowering as the temp increases?

with A Class amps of simple construction, everything is stabilized in that point

In accordance with previous posts:
1st - Device matching seems in some cases to be rather dubious!
2nd - The lack of source resistors appears to be a defining feature of the F5m!
3rd - “Babblefishing” is a term I havn’t darred to ask about yet… 😔
Only as dubious as he who performed the matching. Quite simple actually. Resistor, multimeter, odds and ends all that's needed.
Or buy already matched from reputable supplier.
What are you trying to match? It will take zen mod to explain babblefishing, dumb me, I have to accept on "black box" theory, causing much mistake and nashing of teeth.

In the last three months I have spent more time on this forum than I dare to admit to either my wife, my employer or myself and have apparently still only made it through a fraction of the compulsory curriculum…😔🥺 -So please bear with me.it must be made as condition to even peek a nose on Papaforum
in 10 years, you resident and Cpt. Cook around, even then you'll find someone mocking you

I think it's where ZM uses 10 parts in a circuit where Pa would have used 2, and usually involves a string of green LED's.... 😀 🟢🟢🟢
Yes, I am married. I realized I could easily retire during the covid shutdown in 2020... made me realize I could have retired even earlier.
