Folks:
I'm about ready to look for a replacement for my fine
Sony 5000F FM Stereo Tuner. Nothing wrong with it, but
I'd really like something with AM reception, also. Any
suggestions for a unit that combines both FM and AM
that is comparable in quality to the Sony?
Best tuner around:

For FM it's a good buy although hardly "The Best".
Based on what relevant facts?
To be "the best" it has to be superior to any thing else
available.
No it doesn't. It has a specific function in life - receive radio signals
for consumers to listen to. It doesn't have to be the tallest building in
the world, which is what you're demanding when you say that it "it has to be
superior to any thing else
available."
It isn't as good as a dedicated channelized
rebroadcast receiver,
Nonsense. An apple does not have to be an orange to be the best apple.
it isn't even as good as the
yardstick McIntosh MR78.
You are alone in that judgement.
It's a pretty good FM tuner but
an inexpensive one lacking professional features.
You seem to be very confused. The OP asked a specific question - what would
make a good replacement for a Sony TA 5000F. The Sony TA 5000F is not a
professional tool. It is a consumer radio.
It isn't designed to go into a monitoring facility or a
translator transmitter site rack.
Neither is a TA 5000F or a MR 78.
It has a cheap plastic case,
I'm sure that gauls you. It's also probably made in China.
75 ohm input (everything in real RF is 50 ohms)
One word: consumer.
and no balanced audio,
Neither did the TA 5000F nor the MR 78.
no IF,
Ditto.
no SCA output.
Ditto.
For AM not so much.
Based on what relevant facts?
Performance.
Based on what relevant documentation?
For AM you have to decide whether you want good DX
performance or superb fidelity.
This is an audio group, so the answer to your question
is self-evident.
It isn't because many "audiophiles" include classical or
nonprofit style music listeners in hick towns who have to
get skywave or big town rimshot reception for
satisfaction.
So what?
Equally sensitive but not as selective
are many common old junk yard car radios.
They don't compare with little Sony. I have that from
senior car radio professionals who work for the big 3.
Some of these guys rather dislike Philips for some of
the crap that they have put out in the past have to
admit that this time they did it. Many of these guys cut
their teeth on the radios that you idolize, Bret.
There's nothing like producing radios by the 100,000s
and then putting them in expensive vehicles with
extended warranties to teach people what works and what
doesn't.
Probably the
best ever built are the earlier all solid state Delcos
and Philcos (Ford) up to the mid to late 70s.
They were mediocre, even compared to the best recent
radios that aren't yet based on the same Philips chip
set that Sony is using.
The solid state sets are quieter and have
generally better sensitivity but they do overload
easier.
Simply not true.
While solid state has many advantages, front end headroom
and AGC dynamic range are not amongst them,
You've contradicted yourself. Here's the complement of a MR78:
3 JFET's, 2 MOSFET's, 17 Bipolar Transistors, 43 Diodes, 4 Integrated
Circuits
Read my lips vacuum-brain: No tubes!
at least not on any kind of device-for-device basis.
Nonsense.
Front end RF
tubes operating at 90-200V B+ and especially remopte
cutoff pentodes used in AGC circuits had some wonderful
qualities, and it takes a lot of transistors and
considerable circuit conplexity to even equal them.
Nonsense.
Nobody who is serious about performance is doing tubed front ends in modern
designs.
The other variables are 1) declining interest in AM
performance by most car buyers ,
Now you're faulting this product for being flexible.
and 2) the need to
accomodate FM, cassette tape, 8 track tape or CD players
in OEM sets.
8 track???
Cassette???
Bratzi, do you know what century you are currently in? What millenium?
The latter took up space and build cost budget.
Bratzi, this is the world of SS - the little Sony could have been even
smaller if they squeezed the air out of it.
Therefore there was a range of years in which
car radios improved in AM performance, peaked, and then
declined.
snip vacuum-brain nonsense
