ICOM IC-720 / IC-720A HF Trans. Capacitor Replacement Kit

This is a complete electrolytic capacitor replacement kit (except for a internal or external power supply) for the ICOM IC-720 / ICOM IC-720A transceiver. The IC-720 series is truly a collector's item for the vintage ham radio enthusiast.  Electrolytic capacitors have a design life span which one has to recognize if the intent is to keep your radio running for a long time to come.  Electrolytic's over time change value due to leakage, electrical stress, heat exposure etc., and can be very annoying to troubleshoot especially when intermittent. There are 90 small electrolytic's used, for those who like probability calculations, figure out the failure rate possibility for capacitors that already have 30 years of service!  In all cases the capacitors have been replaced with the exact value of the original, but in many cases I was able to take advantage of smaller modern day components increasing the voltage rating of the replacement unit.

Technical Notes:

** There is no retuning of the radio required as the capacitors being changed are power supply related, or audio coupling/decoupling. Minor adjustment of the VOX controls may be required when new capacitors are installed.

** Installation Time is approximately 4-6 hours from start to finish for an experienced  technician. For all others just take your time and enjoy its a fun project.

The kit is comprised of 90 capacitors.

The capacitor kit shown in the photo is generic in nature as I have a wide variety of kits for Icom, Kenwood and Yaesu.  Capacitors used in the kits are brand new Nichicon/Panasonic; in rare supply issues, substitutes will be CDE rated at 85 deg. C or higher.
