Zoom model 3025 Two ceramic caps have exploaded (lightning hit). I can read 221, but can't read the fourth number on either cap, due to that piece is gone. The cap is rated as 1KV. The modem still works, caller ID and still will connect to the internet, but will only connect at 14.4 or less and has a hum on the line. So it's worth replacing the caps. Not sure if they could be 2200 pf, 220pf. I can tell there is a marking after the 221, but can't make it out. I can't find any caps rated at
1KV that start with 221. Thanks
