Default Re: Graves Vulcan 2 - How to change the tuning range

That's interesting. It seems that the set was originally designed to receive 2LO and 5GB, I'm not sure what frequencies they operated on in 1926-8.

The original tuning dial is calibrated in degrees and goes from 0 to 180, I am picking up BBC Radio Five Live at 80 degrees, so would you imagine I'm receiving the 330 metres or the 443 metres? I'd guess at 433 metres, but that is only a guess.

What sort of value condenser would you advise using to try and lower the range, and where would you try fitting it?
