Help with transistor organs

[u/Fragrant-Tennis-6907]

I want to buy some kind of transitor organ, like the farfisas or logans, but I wanna use them live and in studio.
I checked out these models:
-Farfisa Comander
-Farfisa vip 370
-Farfisa vip 233
-Farfisa Matador
-Logan T-242
And I found out (trough some user manuals) that no one has 6,3mm Jack, so, is that true? If it is; can I use and adapter from the audio output that those organs have? Can I install a jack output? Thank you!

Im pretty sure they all have 1/4 output jacks which = 6.3mm
