Having read a post from another enthusiast about one of these sets which was noisy on long wave, I was prompted to write about my own set. The audio stage is noisy - white noise, at a fairly low level, irrespective of the band or the setting of the volume control - but otherwise the set is fine and in daily use.

It reminds me of one of my old home brew audio projects, which hissed like mad until I cured it by wiring several hundred microfarads straight across the PP9 battery. Before I try this, does anyone have any other suggestions? Are the output transistors in the TR82 prone to this problem?

Thanks,
Phil
