The H2L/7 power-supply is pretty small compared to others. It is not the only one that could be used the En410 and other could also be used. It does not use and tubes.
The vents are visible and the Philips type plate. In this case it says Philips Holland.
The power cable and ground connect.
Here the powersocket to the radio. Again it can be seen that this is basically a tube socket turned in to a connector. The same socket the H2L7/ tubes use.
On the inside everything is very cramped. three blue capacitors are clearly visible most likely replacements. Some parts even have a NA number.
Here the Voltage selector is located. The power-supply can use voltages ranging from 110V up to 245V.
Here one of the Selenium rectifiers can be seen. Also the Chokes and Transformer can be seen.
The bottom cover with nice rubber feet.
The inside is heavily modified. all old parts are removed and replaced by newer ones most likely because the diode produce a higher Voltage than the original selenium ones.
