B&O 1953/1954 Mini 511K valve radio

[Marc O’Rourke]

Hi folks, I am restoring an old 1950’s Mini 511k valve radio. I have the amp section working fine and I can connect a bluetooth module to Spotify from my phone and it sounds great, just need to sort the LW\MW bands and FM.

My question is this, all I can find online is that the radios were sold as ‘FM ready’ and as such has a vacant 8 pin socket on the chassis which is far bigger than any valve. The schematic also only shows an 8 pin socket with ‘FM’ written next to it.

Does anyone have any information on the missing FM module?

Thanks

You would need an FM-module,

either FM 5A:

or FM 6:

Both are immensely rare.
