Re: Have I killed my ZX Spectrum?
The Spectrum is alive and kicking! I changed all 4116 putting them on sockets. I also found that TR4 was dead. And a new membrane also helped. Thank you to all for the help. https://s8.postimg.cc/h88vjd0wx/PIC_20180831_160744.jpg https://s8.postimg.cc/57nfi93oh/PIC_20180831_160810.jpg https://s8.pos...

Re: Spectrum 48k Image quality.
I have discovered today the AV MOD!
It seems a good solution. Some feedback?

Re: Spectrum 48k Image quality.
Okay, so before talking about problems with the ZX Spectrum, it's worth pointing out that with a RF (UHF) or composite video signal, the monochrome picture (containing no colour information, as produced by ZX80, ZX81 etc.) will always be sharper and clearer compared to a colour video signal.

Re: PSU Voltages.
It's mine!
I registered in ZX81, Spectrum and QL forums! One for each. I notice now that the ZX81 and Spectrum are... very equal!
And thank you for your answer for the video quality! I am looking now for your suggestions...

Dear All, I am putting order in my small Sinclair Collection (1 × ZX80 in kit, 1 × ZX81, 2 × Spectrum, 1 × QL), testing everything. I was using one of two Spectrum when it simply turned off... I was a bit scared when I decided to measure the voltage from the PSU and it was 0.9V...I breathed a sigh o...
