I have my old tach and an early version Zeftronics voltage regulator for sale cheap smile The tach was working fine when removed. I replaced it with an electronic version because the tach cable was leaking oil at the engine so capped it off and installed the electronic version. This tach has gone over 10,000 hours but works fine. Free to anyone who needs a OEM tach for the cost of shipping. The regulator I would like to get $50 plus shipping if possible. It was working when removed. Ordered a new one at the direction of an A&P during a X-country flight and the problem turned out to be the starter and not the battery or regulator! So I had the new one installed by my FBO A&P since I had already purchased it.
