Dave Schmarder's schematic uses a variometer so requires having that instrument which you don't. The plug in coils you show in your picture appear to be a broadcast coil and then the next one higher. I used to have a set of those, ICA brand, many years ago, and they look like they were intended to be used with a 140 mmfd. variable cap, which was often used in short wave regenerative receivers. Those coils usually have a label on top indicating their use. The A-K condenser you show probably has a higher capacity and may be 365 mmfd. So far none of this is working out, is it? But stay tuned! Look around for some other regen schematics that give you specs on winding the coil(s) (best to make one for the broadcast band first to get used to it) and that have a regeneration control that is more common: they will typically be either a 50,000 ohm pot or a variable cap. No. 30 tubes are getting expensive but you can use a lot of different tubes for a regen. You might have some tube on hand that would serve. Using a triode would be good for a first regen; some more advanced designs use screen grid or pentodes for smoother control. Things to consider are heater/filament voltage, do you have a supply for same. Regens often work better off batteries: some can have hum problems off of AC. The B+ supply can be several 9 volt batteries snapped together, and the A supply can be D cells on a 1 or 3 volt tube.
