If the radio is intermitent it does not mean that necessarily the
transistor, i think of one probable cause is the variable capacitor
besides if the transistor you mentioned is part of the if section
then you may check with another radio tuning a frequency so produces
an harmonics in the good radio so you know the mixer stage is working
then you can inyect a signal with your finger in the base of the first
if transistor and a radio station should be heard. Have you tried to
resolder all points and verify all paths are in god condition. Hope it
can help.

I think I've found the transistor that is intermittently failing in my
Grundig 305 transistor radio.It is an AF126. I obtained an NTE 160
which is supposed to replace the AF126. however I installed it and the
radio *does not work at all. I wouldn't think that I would have to do
a complete IF alignment after simply replacing a transistor, that is I
would think that even if the new part detuned the circuit slightly, I
would expect to get something through. Any opinions on this? Thanks,

Hi...
I can send You a AF126. You pay the postage, the transistor You can
have for free.

Hi, What do you think the postage to the US will be? Thanks, Lenny- Hide quoted text -
