I set out to make this PCB from konkot (Konrad) over on Github, this is a nice project by him and is an easy to build, It adds AY 3 -8910 to any ZX Spectrum like the 48k rubber speccy ,so all the new games with AY will play with great sound, also if this is added to the +3 model you have perfect sound so you don`t have to do the motherboard MOD.I`ve only tested these on a ZX 48K Spectrum and a ZX Spectrum 128k +3
From the Github site (https://github.com/konkotgit/KAY-Kempston-AY)
