Grundig 87 WE - How to add a pick-up? - UK Vintage Radio Repair and Restoration Discussion Forum

Diniz Diniz · 21st Jun 2018, 12:10 pm

Hello everyone!

I am working on this MW/SW set.
I acquire it only because i needed a similar mains transformer, but I found it in good conditions, so I decided to restore it.

Despite I was not able to find the schematic in the web, the set is now working properly, I believe.

Since it has no FM, I would like to add a pick-up (the set has no such option).

Is it possible to do so with minor changes?
Is anyone able to give me some advice on this?

Link for the set: https://www.radiomuseum.org/r/grundig_87_we87w.html

Many thanks in advanve!

The schematic is on the link you provided (Radio museum).
Although the radio has a mains transformer it appears to mainly be for the heater supplies.
The chassis is not isolated from the mains - R19 47ohms.
For safety I would not advise fitting a Pick up to this set.

Hi Diniz, Please "Search this website" above for "FM to AM Convertor" This is a device that picks up your local FM radio stations and transmits the low power signal to your AM set. I think its the safest way to enjoy your radio.

Good advice. Google [assisted] translation of the RM note on this set.

ATTENTION, NO MAINS ISOLATION, ONLY AUTOTRANSFORMER.
DANGER, LINE VOLTAGE AT CHASSIS.
