I have just come across a large Philips radio I know it as model 125 but on the chassis the sticker saying model 114 K

I don't know which is correct. It's a 6 valve radio.
Thanks George

Well, on that basis, the chassis at least appears to be a 114 series.

Probably they put a 114 chassis in a 125 cabinet

I don't know what the K is for.
Thanks George

I'm not a specialist on Philips sets, but it seems from reading various articles in Silicon Chip that among the various models there were quite a lot of differences between the Dutch versions and those that ended up here.

Pretty much identical cabinets but the guts were nothing alike. On each comparison the Dutch sets either had a long wave option or lots more complexity in the circuitry.

A Philips 114K uses the same chassis as 114B but has a different cabinet. See notes from Kevin Chant:

quite a lot of differences between the Dutch versions and those that ended up here.

European radios were often more complex, one reason being the much higher density of frequency use and re-use, so various tecniques were used to try to increase selectivity and reduce interference from nearby or re-used frequencies. There are still continuous issues raised in the international frequency regulator ITU-R (formerly CCIR). Similar problems in USA, but they fix them locally by arm-wrestling or at the FCC.

Australia has one of the best planned and protected frequency schemes in the world, so receivers don't generally have to be quite so selective.

One other help is oddball IF frequency. The Philips 2462 uses 472.5kHz & HMV Nippers also a decimal point & uneven. That does tend to make it impossible for a hetrodyne at the exact frequency of a radio station.

Some things were thought out.
