Excellent  Time owned: 0 to 3 months
Easy to build (provided you have built a kit or two and are comfortable in measuring high voltages -and have the right equipment). This kit will upgrade your Drake AC-4 power supply with a well designed printed circuit board and the high voltage caps needed. Far easier than sourcing the parts yourself. Colour coded wires reduce the chances of error. Upgrade kits for HP-23, SB-200 and other Heath rigs available as well.

Great product!!!  Time owned: 0 to 3 months
This is a really neat unique upgrade for aging power supplies, where the Electrolytics are going south. It uses heavy duty replacements in a retrofit circuit board that is quick and easy to install. It was described in the Oct. 2003 QST.This QST article is a must for anyone considering undertaking the task. I love the kits, as they supply everything you'd spend hours and hours finding and ordering. Try 'em - you'll love 'em.
