Grundig FR 200 Receiver
 

Hi all !
Need information on the Grundig FR 200 AM-FM + 2 SW bands receiver.
User manual, circuit diagram and workshop repair manual are needed
in order to be able to fix it and then use it when AC power is off,
like during recent hurricanes here.
At the moment the radio works from the external power input at 4.5 volts,
and when using 3 AA batteries, but it only plays for a few seconds
after cranking the Bayliss crank-up DC generator for long periods.
Have someone on the list experienced similar problems ?
It may be that the small three NI-CD battery pack has to be replaced,
or that it needs an external first time charge-up in order to start
working properly ?
Please answer to

Thanks in advance for the help

Go to:

http://www.grundigradio.com/asp/down...nersmanual.asp

and click on the "Download" out beside FR200. I think this is only the
owner/user manual so it may not provide the other info you seek; i.e.
circuit diagrams and repair manual -- but it may be a place to start
looking for them.

Yes, try new batteries first..

The rechargable ones eventually wear out.

I also found there seemed to be vast differences in the batteries in the
FR-200 radios when first purchased. Yes, I purchased several at one
time for gifts a couple of years back. I could crank for a minute or so
and turn the light on to test the life of the batteries. Some would not
even charge if the light was left on. It was using the current about as
fast as I was replacing it.

Therefore, you may want to test the unit's battery condition (in the
store preferably - where they have several FR200's in stock) as soon as
possible and if it is not satisfactory you may wish to return that one
and then buy another.

The request about the LED replacement for the bulb is a great idea. If
anyone learns of one let us all know.

The condition of the battery is probably dependant on how long it has been
on the shelf. The battery pack is some standard cordless phone pack, which
radio shack sells for around $10.

They aren't exactly "standard" cordless phone batteries. It is a nickel
metal pack. They are known to drain off when not being used.

Hi Arnie:
The FR 200 will last nearly forever on 3 AA cells. If you don't
use the flashlite portion one set of batteries will do you through a
couple of hurricane seasons.
I tested the drain on the batteries on this and as I recall it
drew about 6.5 milliwatts at a lower listening level. When any of my
digital radios quit running as the voltage drops to the magic level I
put them into the FR 200 and they play a very long time before
distortion sets in.
Regards,
Bob

what is the bulb number in the fr200? If it is the 1157, a common bulb, the
bulb at aerostich has a LED replacement...

search for 2542 for led replacements for 1157 bulbs....15 Ma vs. 590 Ma for
regular bulbs

HUH? An 1157 is a 12 volt automotive turn signal lamp. It's an S8
envelope and is over an inch across and runs 7 watts or so.

The lamp in a FR200 is a 5 mm long grain of wheat incandescent with
wire leads. There is some sort of circuit to drive it, because the lamp
is running on about 2.5 volts, with about 2 volts difference between
the the + side of the AA batteries. (The lamp runs on either/both the
AA cells and the rechargeable NiMH pack).

BTW, there's a spare lamp in there behind the pop off lamp holder, in a
little recess in the radio case.

But that 7 watts will really light things up.

Someone was talking about using LED's for incandescent bulbs. If you
want to do this the forward drop on them is typically around 1.3 to 1.8
volts. You just need a series resistor to limit the current usually
around 12 to 18 mA. Digi-key will list them with there typical voltage
and current ratings so you can find one for your situation.
