Hi,

a Marantz ST300 arrived in good cosmetic condition and all lights
working - but no audio from either AM or FM. Problem turned out to be
the 28 pin IC at the heart of the unit has gone AWOL.

It's a distinctive looking sod with a metal grounding tab at one end
- as indicated by a few pics found on the net.

But what is the number ?

Reckon it likely starts with "TDA..... "


**I replaced dozens of those suckers back in the 1970s and 1980s.
Extremely unreliable chips. As others have stated, it is an AN7000. WES
don't stock them (of course). I have one in my IC drawer, but it has
been pulled. I have no idea if it works. If you want to take a chance,
it yours for the cost of postage. A better idea might be to call Peter
Lengel at PJL Electronics. There is a chance he has some stashed away
for a rainy day.
