Replacement self-adhesive rubber feet for the Spectrum+ UK1400 PSU

An original internal reset switch for Spectrum+ (used)

• As used in the Spectrum+ (soldered across capacitor C27 - or at the provided pads on issue 6 motherboards)
• Tested, working.

Membrane cable clamp screw - new

• New replacement screw for the clamps that hold down the membrane tails in the Spectrum+ case

Replacement foam pads for Spectrum+ legs

A pair of self-adhesive foam pads to replace those found on the Spectrum+ support legs (which often will have crumbled with age)

A pair of 2.2K trimmers (variable resistors)

• As used on Issue TWO Spectrum PCB for adjusting colour output  (the old trimmers can become intermittent and unreliable) 
• Two supplied in this pack.

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!)
