Re: Sun Tach ST-601
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: jeffschevelle</div><div class="ubbcode-body">Does anyone know what year the Sun ST-601 was originally released? (I tried google first with no luck.) It is the 10K rpm half sweep style tach.
From what I can find on line this model tach does not use a separate sending unit like the earlier tachs. But the car I am working on had the ST-601 tach (mounted in an earlier style cup), and a separate sending unit, all in one box in the trunk.
Any help would be appreciated! Thanks - Jeff

Jeff,
I checked my old Honest Charley catalogs. The ST-601 is listed in his '67 catalog and it mentions it's a new line. It's not in the 65 1/2 catalog. Oddly though, the 65 1/2 catalog had an all electronic one listed, model RE with a 90deg sweep. Higher model numbers did not necessarily mean they were all electronic though. The first ST-700 series still required a sender. I'm pretty sure the first all electronic 700 series was '68 and it had a white needle. By '69 they all had a red needle. (I have both and they're dated)
Hope this helps.
Verne
