Most studio strobes have optical slaves incorporated. Older studio strobes cannot be adjusted in power from the camera but, must be adjusted at the strobe itself. So, all one needs is a trigger which will fire the strobes.
I have a very cheap but, extremely reliable trigger for the older strobes which I use effectively with my White Lightning ("coffee can") WL-5000 strobes. https://www.ebay.com/itm/221946563874
I have been using one of these triggers for years with no problems until I forgot and left a set of cheapie batteries which leaked and ruined the unit. I was able to find a replacement for less than twenty five dollars including shipping...
The only downside of his unit is that you need line of sight between the trigger and the slave of the strobe. However, you only need L.O.S. to one of your strobes since the flash from that strobe will trigger all the strobes which have optical slaves...
Sure, using a more modern radio system is perhaps easier since I can adjust the power of my units from the camera position and I can group my strobes but, this little trigger does the job quite well to just fire older strobes...
