It won't be easy to find (dual "CF" OpAmp in DIP package) - they usually dissipate a lot of power (heavy current users) so something like AD811 (single/DIP) or AD815AYS (dual/SIP-15) is what you can aim for...
Thank you.
preamp what?
home audio today the "generic preamp" function is not the big deal it was decades ago
today most have digital audio outputs already at consumer line level and maybe a phono preamp - which is usually its own separate thing
It is nice to have input selector, volume control, and line pre-amp with a little voltage gain.
AD8017 - but its SO8 so you'll need an adapter.
I hope you're not intending to retrofit CFA in place of VFAs
I just want to try. That it's. I have experience to design a CFA amplifier, don't worry, I think I have enough knowledge to implement it.
Btw, thank you.
AD844 ?
-RNM
Thank you, Mr. Marsh.
I will check the datasheets, parts availability and of course the price
Maybe you could try LT1364 it`s a VFB with the CFB structure inside. Look in datasheet for schematic. It sounds great!

I always use VFA op-amp like NE5532, OPA4134, TL072, TL084, etc. I want to try CFA op-amp for line pre-amp. Please suggest me, what op-amp should I use. The op-amp must 2 op-amp in single package and DIP package. And cheap also .
Thank you,

Hello everybody.
I don't know if I understood correctly. do you want to associate a volume control with a preamplifier on the line? if so, it interests me too.
in a resistance-scale volume control, double resistances and double contact are required. with operational CFA it is possible to use only one resistance and only one contact?
