We have completed the following work:RDR Spectrum 48k - 001-052148-IMG_3215

  • Changed the RF output for a composite video modification so that it will work on all modern TV’s through their AV Video phono connector.
  • Checked and replaced any electrolytic capacitors that were bad – in this case a full re-cap.
  • Lower RAM caps replaced with 1uF to improve video output.
  • 1 lower RAM chip socketed and replaced.
  • TR4 and TR5 replaced, D15, D11 and R55 replaced.
  • IC16 to IC25 replaced.
  • Resoldered crystal oscilator.
  • Cleaned the cases inside and out.
  • Fully tested the Spectrum with diagnostics for a few hours to make sure RAM was working well. All tests passed.
  • Tested it playing games.
  • Tested every key to make sure the keyboard works.
  • Tested the electrolytic capacitor in the ZX power supply and fully tested its output.
