Yes, you could, but I'd replace all of the capacitors and then do a power up. You can get a cheap CRT tester on eBay for $20-40. I haven't run into too many 10-12" crts that were completely dead, so you can just recap it and see if you get a raster. Just make sure you pay attention to the electrolytics. If you're just beginning, it's easy to think all electrolytics have one side going to ground, because in most radios that's the case. Any tubular, black cardboard electrolytics are not grounded and must be wired identically the way they're laid out. Ask any questions you have, the guys on here are very knowledgeable and helpful. When disconnecting the chassis after each power up, ground the second anode connector, before disconnecting from the side of the picture tube. Otherwise you'll get a pretty good shock.
