minerva: MW30; Minerphon

Dear all,

 

visiting the Olens Radiomuseum (Belgium), I discovered a radio that looks very similar to the MW30. It carries no manufacturing label, the front gives only the letters BNS.

There is one tube missing, the tree others are

 

• B409 (Philips)
• 4G30 (TE KA DE)
• tube n° 3 has a top screw connection but unfortunately it lost all of its its gray shielding painting. I think that I can read on the remains RENSxxxx...

Questions:

• is this a real MW30?
• What does BNS mean?
• The tube line-up according to RM Org is different, but contains NO tube with screw top mounting. 
• what is the brand of the large capacitor at the right?
• can anyone upload a copy of the circuit diagram?

Please see pictures

Dear Mr Knoll,

 

thank you for your answer. This has allowed us to identify the set.

It is indeed a Lumophon, only the label at the left of the radio is missing, and I think it has no original tubes.

The case of the Olens Museum radio in not in wood, but in pressed paper.
