Default F2 for beginners

Hello chaps

I am a refugee from the land of SET so please forgive the naive question..I'm an absolute newby with SS.

I want to build an F2 for my fostex folded voigts just to see what all the fuss is about. I have read the background on the F1 service manual and tried to understand the circuit that Nelson kindly supplied in the clone thread, BUT............

I can't see a +out on the diagram and as the ps is floating vis chassis via the thermistors, i couldn't make sense of it.

Can anybody enlighten me on this please.

Regards

Ed

Since the circuit is inverting, the + output is ground and the
- output is the active output. Hook up the speaker that way
and it will work as intended.

Is there actually a difference as long as both speakers are connected equally (- to + or vice versa)?

Many thanks for that, and again, apologies for the naivity.

Regards

Yes. It's subtle enough that most people don't notice or care, but it's there. It's most noticeable on something like a bass drum.

But, actually, might it be advisable to try both connections???

No one will arrest you.
I promise.
But I cannot promise that they will not snicker behind your back.
