Broken Thermistor in Philips N3G25T Car Radio
I am currently repairing this radio for a friend who has an old Ford Consul (lucky man!).
I have fixed the original fault, which was no results on either LW or MW (it was down to an internal "whisker" short on one of the AF117 transistors, TR2). However, before I can hand it back, there is another problem - the VDR designated R26 is split in two. There are no markings on it, and no type number is given in the circuit diagram (see photo). Would anyone happen to know of a suitable replacement? Thanks in advance! Last edited by Potless; 4th Jun 2019 at 2:45 pm. |

Re: Broken VDR in Philips N3G25T Car Radio
It's a thermistor not a VDR. The manual just says 130 ohm Varite. Not easy to find nowadays, good hunting.

VA1040 specified as 130 ohms at 25 degrees C if you can find one:
