• As used in various locations the PCB (usually marked "104" on the body of the cap) of the Commodore 64, Spectrum and other micros 
• Ceramic capacitors do not age in the same way as electrolytics so usually don't need to be replaced, but they are quite fragile and sometimes found physically damaged.

Ten 10nf (0.01uf) ceramic disc capacitors

• As used in various locations the PCB (usually marked "103" on the body of the cap) of the Commodore 64, Spectrum and other micros 
• Ceramic capacitors do not age in the same way as electrolytics so usually don't need to be replaced, but they are quite fragile and sometimes found physically damaged.

Ten 22nf ceramic disc capacitors

• As used in various locations the PCB (usually marked "223" on the body of the cap) of the Commodore 64, Spectrum and other micros 
• Ceramic capacitors do not age in the same way as electrolytics so usually don't need to be replaced, but they are quite fragile and easily damaged.

Ten 4.7nf ceramic disc capacitors

• As used in various locations the PCB (usually marked "472" on the body of the cap) of the Commodore 64, Spectrum and other micros 
• Ceramic capacitors do not age in the same way as electrolytics so usually don't need to be replaced, but they are quite fragile and sometimes found physically damaged.

Ten 47nf ceramic disc capacitors

• As used in various locations the PCB (usually marked "473" on the body of the cap) of the Commodore 64, Spectrum and other micros 
• Ceramic capacitors do not age in the same way as electrolytics so usually don't need to be replaced, but they are quite fragile and easily damaged.

Z80 CPU - New

• Brand new Zilog Z80 Central Processing Unit for Spectrum (and ZX81, Amstrad CPC etc)
• Modern lower-power CMOS version, direct replacement for NMOS originals.
• Date code around 2022 (just before they stopped production). 
• Replacing the CPU also solves the known issue with out-of-spec Z80s sometimes found in Spectrums. (ie:  external interfaces not working correctly due to weak signals, usually bad "M1")

Z80 CPU - Original NMOS part - Used but never soldered.

• Original NMOS type Z80 Central Processing Unit for Spectrum (and ZX81 etc)
• Manufacturer will be NEC, SGS, Mostek, Zilog etc as many companies made Z80s back in the day
• Tested in a Spectrum - (checked "M1" signal etc)
• Straight, full length pins

Z80 CPU -  Original, NMOS type - New, old stock part

• Genuine vintage 4MHz NMOS Z80 chip from 1988 made by Goldstar - NOT a re-marked modern fake
• Unused old stock part - tested & working (/M1 signal good too)

ZTX313 Transistor

• Often found in the Spectrum 16/48 at TR1, TR2, TR3 and TR6 locations.
• Also used in the ZX81
• Genuine original old stock parts not modern fakes.
