Jim thanks for the tips.

I am just dissapointed that with todays modern technology the tachs seem to be worst that ones made 15 - 20 years ago. My friend had an old Heathkit one that worked great and I had an anolog one made by Royal. Both worked flawlessly. I think we both paid less than five bucks at swap meets for them. I remember that after 5-7 years use I sold mine for a lot more that I paid for it. Boy was I stupid!

So are there any tachs out there that work well? (That are still made)
