Has anyone here successfully replaced the front panel bulbs on a 650?
I'm down to one working bulb - the one on the preselector dial.

I ordered some bulbs from Mouser, and they are the correct size. But
the base is just a tad too wide and they will not fit into the sockets.
So I'm thinking of replacing the sockets. But I thought I'd ask here
first if anyone knows a source of true replacement bulbs.

According to this page:

http://www.geocities.com/grundig_satellit/

they are OSRAM bulbs, 6-7 volt. Three of them are rated at 30ma, and
one is rated at 80ma. The 30ma bulbs are Osram #2306. I don't know
the number of the 80ma bulb.

The bulbs I got from Mouser are Chicago Miniature Incandescent bulbs,
6.3V and 20ma. These were the closest I could find.

Any ideas?

Have you considered white LED's?

If you're concerned about keeping it original for collector purposes
it's a bad idea, but they'll last a very long time.

No, I hadn't thought of that. I'm not really concerned about keeping
it "original". I'd rather have it working!

I'll look into LEDs. Thanks for the suggestion.

Remember that you will have to add a series resistor to limit the
current in each LED, otherwise they won't last long. Use Ohms law to
calculate the resistor value based on the source voltage and the
voltage/current ratings of the LED. I replaced the fifty-six (no typo!)
green LED's in my R8B display with just four bright white ones. The
display now looks blue-green with white charecters. The R8 was designed
before there were bright LED's, so Drake had to use an array of many
dozens of less bright ones to backlight the LCD display.

I *think* I might have found some original lamps for a decent price. I
have emailed them, and will report my findings.

Wait for Brenda Ann, she put some in my radio.

Are you sure of those numbers? None of these numbers appear in their
lists. I searched on 0084-WI, 84 01-I2, EIKO, etc.

Thanks

Looks like bulbdirect may has changed their site. Can't find Eiko
lamps there using search. I'm looking at my receipt so I know I
purchased them there. Anyway, the manufacturer site is:

http://www.eiko-ltd.com/eiko/item.asp?qid=166&lid=84

That's th actual bulb on that page. It fits. You can probably find
it at Mouser or DigiKey.

Hope that helps. I'll keep looking and post if I find it. Regards

Look for BULB LAMP P/N "84"

Looks the same.
