Hi all!

Somebody in a previous post has asked about mixing and matching ba3 with f5. Has anyone tried that?

If someone (me) tried to use ba3 as a unity gain buffer would the adjustment of the gain resistors ratio suffice or other adjustments have to be made?

What about the input of the ba3 in the above case?

hm? I guess you are talking about ba3+f5?

I was just thinking about it, that's all.

But using ba3 as a unity gain buffer I'm serious about if it can be done and how.

Thanks Zen!

Do you think the combo of ba3 as a buffer and f5 is a good match?

Do I have to change anything at the input of ba3?

well - I already told you - if you can go without it ...............

no need to change anything on input

read my comment in Papa's BA3 article - with proper parts nomenclature , and everything will be clear

My new BA3 powered up well. The bias has been set as per schematic. Can't wait to mount the crippled F4 transistors and put the system to sing.
