About Surface mount technology :
Can you hear the difference? - no, this is a " smelling the cork" discussion. Surface Mount, is more reliable, with a reject rate 100 time better than some error prone older components with greater failure rates.
I know, we passed on the surplus transistors that were in the wild,. Why did we pass?... because of the error rate of that component. Do you want a failure in the middle of your session?
We use a combination of Thru-hole and surface mount technology for todays best performance and longevity
Having said that , we are offering our older thru-hole model at the same price for those who want them, but with a warranty period of just 90 days. The warranty period of the op amps pictured is an astounding 5 years, and 10 days. Just let us know when you order.
THIS IS THE GENUINE MELCOR ITEM. We say that , only because we have that mark. There are other available in the market place, so find the one you like . . . . there is a ton of them out there . . .but this is the one we are making . . . we have more favors coming . . . like eveyone .
