In this video I repair \ restore a faulty Sinclair ZX Spectrum+ 48K.

The Repairs & Mods I cover in this video, not necessarily in this order.

Repair a RAM \ Memory initialization issue.
Install a new keyboard membrane.
Replace the old Capacitors by installing a fresh Capacitor Kit.
Composite Video Mod.
Total strip down of the system and cleanup.
Install a new Reset button.

I have to confess I make an error in this video. I totally overlook the system have an underlying RAM fault that I have to repair later in the video.
