I have an ICF-2010 (serial 95047) that I am considering selling. Using the 1620 test, it appears to have a blown FET Q303. The receiver works well but I understand that a blown Q303 greatly reduces reception.

I can find a lot of information on the web via the 1620 test and this model, but no available repair kits. Is there someone who specializes in the Q303 repair...if so, who? What is the value with and without the Q303 repair?

TIA,

Terry

Q303 is a 2SK152 N channel JFET

Easy enough to replace, along with the four back-to-back 1N914 protection diodes.
Plenty of 2SK152's and 1N914's on ebay.

Service manual and numerous replacement guides are available on-line.
