While this isn't TV related, it is CRT related.

I've been working on a TRS-80 Model 4 power supply and after recapping and double checking, I still managed to mess it up by putting a capacitor in backwards. Upon firing up the unit, it all seemed to go well, but when I accessed the disk drive, the screen dimmed and shrank with a pfft sound and magic smoke came out of the upper left. This couldn't be the power supply as it is centrally located. It had the be the video board, so I removed it and found a tantalum with a nice hole in it. I figured that since I had to replace that, I might as well tackle all the electrolytics and order all noted values. The caps arrived yesterday, but there is one that my brain just can't accept, but it might be right. The original cap is a 10uf 25V NP. That's what I ordered from a short list of available caps. I knew it was smaller, but this is crazy. The original is 15mm x 35mm with 10mm leads. What I got is 4mm x 10mm with 2mm leads. From the schematic (C322), this cap is in the horizontal circuit before the yoke.

I'm attaching the section of the schematic as well as the size comparison pic. Will this little cap actually work, or do I need to get one with higher voltage in order to get something similar is size (12.5mm x 25mm)?

Thanks!
