You can see the capacitors in these pics. The schematic will tell you the values and how many you need (link below last pic)

The main thing is buying caps that have the same or higher voltage ratings of the originals. On electrolytic capacitors in the power supply that help smooth out the dc after the 0z4,
one should use caps that are at least within 50% the same rating as original and the same voltage or higher than original. Other wax caps should be replaced with values that are the same. The buffer cap is the one across the "points" of the vibrator. It usually has a voltage rating of 1600 volts. It helps to keep the contacts within the vibrator from arcing.

Capacitors and resistors are available at several places but I found most all of the capacitors I needed at two places. Just Radios https://justradios.com had a few in the same specs as the originals and Antique Electronic Supply https://www.tubesandmore.com/products/capacitors had the rest of them. For my 47 I felt Antique Electronic had the better selection of capacitors designated closest to if not identical to the original specs.

Although Iíve never tried them, you can also get solid state vibrators at places like Antique Electronic Supply but check the reviews and comments about pin-outs first.
