I can’t find the IC CA3094 but I’ve read in the forum that I can make one
using a CA3080 and a FET.
Can anyone tell me how to build a CA3094?
Thanks
Steve has them. :D

I hear that the LM13700 is a possible substitute (not direct, the 13700 is a dual).
Also, a CA3080 plus a darlington follower:

Would work. You could try 2n2222s or 3904s and go from there. I'm not sure what Re should be in this case, anyone?

Thanks.
Could you tell me where I conect the Vin and Vout?
Do a search in the archives of this forum - there's a large body of information on OTAs and substitutes for the CA3094. FP / tonepad has documented the subtitutes in his/their Small Stone or Ross phaser build - check it out!

Vin is basically from the output of the opamp, Vout is the new output.
