grundig: 1098WE ; tranformer used in the power supply

Hi,

How can I find the specifications of the transformer used in the power supply of the 1098 ? The unit I've has a short circuit.

It may also be a very standard model of that time, with very standard behaviour, so anyone with sufficient experience to guide me to an equivalent - and where to find it is very welcome !!!

Thanks a lot

MARC

6.3VAC at 2.2 Amps
200VAC at 65mA

Well, it is what I would call "ordinary good radio with one 6V6". Yes this has EL84 which takes similar plate power but a little more heater power; not a large difference.

The "non-standard" thing is: it has a solid-state rectifier. Tube RF/IF/AF with solid rectifiers were made for only a few years between all-tube and all-solid-state.

You can easily find a new power transformer for "Fender Champ", a guitar-amp which is essentually a good 1950s radio without a tuner. It is still popular in the guitar community, both vintage-repaired and from-scratch recreations. However Champ is usually built with 5V3 tube rectifier, and also intended to be LOUD, so the HV winding voltages are much too high for the solid-state rectifier and a mellow table-radio.

Dear Marc,

check first if short circuit is in external components, as the selenium rectifier or the heater wiring. To do this, you can disonnect one of the two wires for each secondary winding. When you are sure that the transformer has to be replaced, you can easily find an acceptable replacement. You can try here.

Best wishes, Emilio
