15 Ohm 1 Watt Resistor

• A large hIgher power 15 Ohm resistor used at position R34 on Spectrum boards
• Sold individually

15 Ohm Resistor 

• Used at R62 - Can easily burn out especially if there has been smoke / problems with TR4/TR5
• Symptoms when bad: Spectrum essentially OK but very dark / no / monochrome video (and unnaffected by trimmers on issue TWOs). Pin 14 of LM1889 (IC14) is a lot lower than 12v.

3 Amp Fuse for UK Mains Plug

• Appropriate fuse for the UK mains plug of Spectrum, Commodore 64 etc
• Brand new, made to BS1362 standard - ASTA approved.

7805 Voltage Regulator

Replacement 5 volt regulator IC for the Spectrum, (breadbin) Commodore 64, ZX81 etc

Heatsink for issue 3-6A Spectrum PCB

• Original, used part in good condition.
• Includes standard slotted 4BA cheesehead bolt, shake-proof washer, insulating washer and nut.
• When fitting: Bolt passes through washer, then 7805, then heatsink, then PCB, then insulating washer (only required if your board has nearby traces, EG: the 6A), then nut.
• Note: 4S (Samsung made) boards used a brass Philips head screw, this isn't particularly important but I have those listed above if required.

New internal reset switch for Spectrum+ or Toastrack 128

• Brand new
• Same as original reset switch but has a light grey plunger instead of brown/black (Note: if you have an original reset switch that has gone bad, you can actually swap the original plunger to the new switch body by gently tilting it to the side until it comes out (care must be taken to avoid breaking anything.)
• For Spectrum+ and Toastrack 128

An original internal reset switch for Spectrum+ (used) and Toastrack 128

• As used in the Spectrum+ (soldered across capacitor C27 - or at the provided pads on issue 6 motherboards)
• Also used in the Toastrack 128
• Tested, working.

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!)

New speaker module for Issue 2 (only) ZX Spectrum motherboard

• With suitable 200 Ohm speakers seemingly impossible to source new, I've designed a replacement module. It uses a standard low impedence small speaker but with a buffer and amplifier so that it still presents a ~200 Ohm load to the Spectrum.
• For Issue 2 boards only (from Issue 3 onwards, a 40 Ohm speaker was used - see below)

New speaker module for Issue 3-6 ZX Spectrum motherboard

• A replacement module for the original 40 Ohm speaker as used on Issue 3 boards onwards
• Issue 1 and 2 Spectrums used a 200 Ohm speaker, see above.

New power transformer coil for Spectrum 16/48K PCB

• Part of the circuit in Spectrums that generates the -5v and 12v power rails.
• These are brand new transformer coils made by myself.
• All tested before dispatch.

BARE transformer coil former for Spectrum 16/48K PCB

• A * bare * ferrite core former and mounting PCB / pins.
• No coil windings! Suitable enamelled copper wire is available below. Instructions are provided.
  
• Brand new - made by myself.

2 Metres of 0.3mm gauge enameled copper wire

• Suitable for repairing a Spectrum power coil
• Instructions provided
