Puck,
Can you or someone please explain this
phenomena (did I speel that right?)
of a memory chip filling and requiring replacement?
I am not familiar with this tuner, but I am quite surprised
to see a requirement of replaceing a full memory chip.
the caps and inductor I can figure out, but I would like to
learn more about this memory chip. I am assuming the following:
this is a auto tuner, and continas an EPROM (not ram or EEPROM)
that can be written to but not erased. after a cetain (I guess many
hundreds) number of setting and saves, the chip is full, and can no
longer save new tuner settings?
