I know I'd love to find an example and yes, I'll bet it was a splendid performer. I have two of the mains version, the EU15.

I have a brochure for something much later - the BE75, which looks like the EBS64. Sadly, that brochure doesn't tell you the valves used.

To improve performance I've decided to use a different set of valves. The frequency changer will be a DK40. The IF amplifier a DF91. The second detector and audio amplifier will be a DAF91. Like the DK40 the output valve will be another special valve developed by Philips for high performance battery radios, the DL41.

 The circuit is a Philips design to exploit the D40 series battery valves. Thanks to the superior performance of the DK40 frequency changer valve reception is excellent on all three wavebands.

 The objective of this project was to create a dry battery version of the Bush BA91 which can house the batteries inside the cabinet.
