Eico 723 CW Transmitter Restoration


Recently, I purchased this Eico 723 transmitter from a fellow ham. The transmitter was in such great over-all cosmetic condition, that I decided to do a complete electrical restoration. Not having the assembly manual, I took many pictures before totally disassembling the rig. Luckily, the operation manual and schematic were available on the Internet. The transmitter has a replacement power transformer that requires a full-wave bridge rectifier to produce the necessary high voltage. Here are a number of before restoration and after restoration photos. The transmitter will put out around 40 watts.
