He's just a little north-west of Croydon, between the A23 and the A24. Where the best action movies are made.
Mitchum or Blackburn for the Mullard 6922?
Do Mitchum production and Blackburn production sound different in the Mullard 6922? I believe I once read somewhere that Mitchum made tubes for the military, whereas Blackbutn did not, so, presumably, with better materials and/or tighter tolerances or testing.
