Replacement DC jack plug for Spectrum UK1400 PSU

Replacement DC Jack plug for Spectrum PSU

  • A good quality, high current rated replacement for the original PSU jack plug.
  • Remember when soldering: The Spectrum PSU is unusual in that the inner pin is negative and the outer barrel is positive. (Getting these reversed will fry your Spectrum!)

Spectrum RF TV Modulator UM1233 UK, PAL

Spectrum RF TV Modulator UM1233 (UK, PAL)

  • Original salvaged part, de-soldered from PCB
  • Tested: Decent RF output (little in the way of grain, waviness or flaring - but remember, RF is never Composite video standard)
  • Also used in the ZX81 and other computers
  • Note: Always re-cap the Spectrum motherboard before suspecting the modulator as being the source of a poor display.
  • To save postage costs (ie: to fit it in a large-letter size box) before dispatch I splay the two mounting lugs outwards - these will need to be straightened again with pliers before fitting.
Price: £ 3.95   Add to cart. (out of stock)
