Description

TA7642 AM Radio Receiver on a Chip TO-92 Case
2/Lot: Great Hobby IC
Easily build a miniature AM Radio.
The TA7642 is a single chip AM Radio
Integrated Circuit
(IC) with AGC.
It replaces the ZN414Z, and the MK414 radio IC. It is also the most
recent upgrade to the nearly identical MK484. In fact you will often
see this listed as TA7642/MK484. To be honest with you, I have
looked at both circuits and do not see any difference.
In a tiny (to-92) transistor size case, a ten transistor tuned RF circuit
that requires no setup or alignment.
Nearly a complete circuit; add battery (1.1 to 1.6 volts), tuning coil
and capacitor and crystal earphone.

A Note to International Customers:
First I want to say that when we receive an order, it is shipped promptly within 1-3 days. Once the order is brought to the post office and shipped, it is out of our hands. Delivery outside of the United States can take anywhere from 1 week all the way up until 12 weeks (Typical though is one to four weeks).
There are numerous reasons for the delay. Typically, packages are delayed in customs, first in the United States and then in overseas customs. We cannot control the time packages are in customs.
If you contact us to see where your item is, and we tell you it has been shipped, that is all we can do. On small packages, we do not use delivery confirmation because of the high cost. The cost to use confirmation overseas will far exceed the price of the item purchased. If the package has not arrived by 12 weeks, we will issue you a refund or a replacement if the item is available.
According to Ebay statistics, only 19% of sellers in the United States will ship overseas. And according to Ebay surveys, those who do not ship overseas site customer complaints from long delivery times as the reason.
We have chosen to do business with our international friends. However, we ask for your patience. Too often we get emails asking where my item is when it has not even been a week or two.
Our next choice will be to either discontinue international sales or charge for delivery confirmation which will add considerably to the cost.
Please be patient.
Note, it is the responsibility of the buyer to pay all and any custom fees. We do not know how much these fees are. You will have to inquiry within your own country.
Thank you
