I need help replacing a defective an unidentified silicon diode on a Heathkit AJ-14 Fm M Tuner. I am thinking of using a generic diodes from 1N4001-1N4007 series. Any suggestions will be appreciated.
Hello,
Thank you for contacting DigiKey Technical Support.
Do you know what specifications the diode, we will not be able to get much information from the device. Is all that diode trying to do is block current in one direction?
Do you know how much amps and volts is going to go through the diode?
Hello @w0673,
Is the circuit board near the diode marker D300 or is it something else.
BTW, Heathkit is one of the classics. The schematics are relatively easy to find on the web.
Looking forward to your response.
Happy soldering.
Aaron
Researching the internet, I learned that IN 4001 may be an adequate substiute since the schematic shows incoming a/c voltage @11.5 volts and the IN4001 is rated at 50 volts max. Fortunately I had some on hand. So I am going to give it try. Thank you for the help. Peter
Aaron,
I am going to try a IN401 as I stated in my post earlier. One aspect of the Heathkit Aj-14 FM tuner is it’s sensitivity to distant FM signals and the stereo separation is awesome. I built this tuner back in 1974. It has laid dormant for years. So a little TLC might bring it back to full life.
