ZX Spectrum 16 / 48k Computer replace electrolytic capacitors and composite video modification


Replace Electrolytic Capacitors and Composite Video Modification for your ZX Spectrum 16 / 48k computer.

The composite video modification will use a PCB which will fit inside the RF modulator on the Spectrum’s motherboard which will allow you to continue using the same RF output socket.  You will connect this to the video input on your television.  The PCB has been designed to clean the signal and amplify it and produces a fantastic, bright picture.  Jailbars (vertical lines on the screen) after the modification may be more prominent.  We can make these better by changing some extra ceramic capacitors for an additional cost of £5.00.

Parts are included in the price and return shipping will be added to the final price once the repair is complete. You will need to post the item to us.

Pictures are for illustration only, but good quality capacitors are used.

    Got my Spectrum done at the same time as my zx81 and again delighted. Composite mod is excellent and memory problem fixed – was showing and 16k instead of 48k. The pictures and and video of work and testing much appreciated. All done fast and good prices. Will be back for more upgrades. Highly recommended.
