Tek 475 chopper failure


JOSE V. GAVILA (EB5AGV/EC5AAU)
 

Hello!

Well, after some time working with radio gear, now I am back to test
equipment... Last time I powered my Tek 475, I found that the chopper
circuit no longer worked. CH1 and CH2 work fine sepparately and also in ALT
mode. But no in CHOP mode. So I guess it could be related with the
oscillator in the chopper. Any hint?. I plan to work on it soon. Now I use
the 485 or the 7603 to work. It is nice to have backup gear :-)!

Regards,

JOSE
