telefunken: 7; Opus

Can someone provide any information for the original power (mains) transformer for this radio.

What would be a good replacement power transformer, what is the voltage and mA for the B+, and what is the amperage rating for the filament?

Does anyone have any information for the orginal "Hannover" transfomer?

The present transformer works but is vibrating (I did tighten the four bolts to the trans).

Any sugestions on what should be done?

Kindly appreciated!

After much web surfing and searching many sites that sell transformers, I found a transformer manufactuered by the Hammond Company , Canada, that has a 117vac primary, a 275vac (125mA)secondary, and a 6.3 vac (4 amps) filament.

Here is an example of a Hammond transformer mounted on a Telefunken Opus 9u.
