That's the "Buy it now", not the reserve.

$700 reserve price, wow!


Still too high, I paid less than that for a nearly mint Kenwood TS-

First, it's none of your business what the seller asks -- if you don't like it,
don't bid on it.


LOL, you need to relax, and calm down. I'm assuming you're the seller
maybe? If not sit down and chill a little.


Secondly, "too high" depends on whether or not it sells at that price, not your
(or my) opinion.


Please get a life. If you aren't the seller, why are you so upset?


Thirdly, the price of one Kenwood has very little to do with the value of a
different model.


Since the TS850S is a much better receiver than a R5000 (if you dispute
that, well, it's your opinion alone, for the most part), AND has a 100
watt transmitter in the same box, it should be worth more.


I've owned 2 R5000's. Nice audio, but $700 is just not a realistic price
for a 20 year old, or close to it, receiver that runs very hot on AC
power.


I'm not so sure about the 'very hot' part. I've had one, didn't run hot, nor does the
Drake R8 series which some think run to hot...


...and now, back Michael Savage.

I guess the mods to move the regulators to the outside were just for
grins, right? I had two of them, and they ran way too hot on AC power
for my tastes. Those regulators were super hot.


Super hot?????????? Not hardly.


If you would have taken
the cover off, it was more than obvious. I wonder how many R5000's
failed due to one of those regs cooking itself to death.


I haven't heard of one. The receiver has been around since 1987 so I
would assume that stories of R5000 receivers burning up from "super
heat" would be all over the net by now. How many failures have you
read of that are traceable to overheating. Indeed how many of those
receivers have failed for any reason. Not many in my experience.




I don't know how many failed, but I've touched those regulators and they
were hot enough to burn my fingers. In my book, that's too hot! You may
disagree, but for me, it was a good reason to run it on 12 volts. Just
like my Icom R7100 another hot runner on AC power, it ran too hot for
it's own good.

Dont know either, but I know mine ran HOT. And just for the lost energy
alone it was enough for me to decide and buy an external 13,8v supply.
Now I can safely put something on top of the rx again (like a logbook or
guide) without having to worry about all that heat...

And I've owned stereos that put out some heat but ran for years. The
real question is whether Kenwood engineers considered the heat in the
radio design. Given the radio's excellent design, high performance
and record of reliability I suspect they did. The radio was well
vented so the heat was dissipated.



And that excellent design, did it extend to the stock wide AM filter?

LOL.

If the part normally runs so hot it will burn fingers, that's too hot!
And that's with the case off. I've never had a stereo amp or receiver
that ran as hot as both my R5000's did, and I've had a lot of equipment
over the 40+ years since I bought my first stereo receiver in 1966.

Roadie,


Some peope who own the Kenwood R-5000 Receiver
have reported 'internal' Component Failures that they
reasonably believed were caused by the Receiver
Running HOT ! - - - IIRC usually these Failures were
"Fails to Power-On" and 'The Fix' was the replacement
of Components in the 'built-in' AC-to-DC Power Supply.


But - The vast majority of Kenwood R-5000 Receiver
Owners/Users have had many years of Trouble-Free
Operation of the Receiver all the time while the Receiver
was Running HOT ! - By Design -is- not necessarily a
design flaw.


QUESTION - Are you 'interested' in the Kenwood R-5000
(R5000) Communications Receiver ?
? Want-to-know-more-about-the-Kewnwood-R-5000 ?
KENWOOD =http://groups.yahoo.com/group/*kenwood-r5000/
.
Then you are "Invited to Join" the Kenwood R-5000 (R5000)
Communications Receiver Group on YAHOO !
R-5000 =http://groups.yahoo.com/group/*kenwood-r5000/
.
NOTE - Many consider the Kenwood R-5000 (R5000)
Communications Receiver to be 'the last' and 'the best'
Full Coverage Receiver made by Kenwood. {I Agree }

Already a member, thanks. It's one of the more informative Yahoo
