Hi all,

I too am restoring one of these 37-624 sets. Mine still has the original Philco cap. The part number on it is 30-1271-X. It is marked non-polorized and is 8uf and 2uf at 200VDC. This is just in case the battery is connected backwards. I just purchased some 8.2uf & 2.2 uf film caps for use in this restoration. They are quite large, however if you have an old electrolytic can that is tall enough, you could restuff it with these caps. they are available from AES. Part number for the 8.2uf is C-FS8D2-630 and for the 2.2uf is C-FS2D2-630. I also purchased a 4.7uf for part number C-FS4D7-630 to use with the 8.2uf to restuff the filter cap next to the vibrator p/s. It was a tight fit, but I slightly modified the metal case to get all to fit and stacked them end to end. I just finished repairing and restoring the vibrator power supply and these film caps work great. It puts out 155volts DC with no ripple observed on my scope. These are film caps so polarity is not a problem. I did need to unsolder and pull the end cap off the vibrator and clean the contacts. I used some alcohol and a relay contact burnishing tool to clean the contacts. I then had to slightly tweek one of the contacts to get the square wave equal height and duration. And yes I did restuff the three metal can caps in that p/s as well as the buffer cap. It should now last a long time.
Feel free to email me with any questions.
