component values sinclair x10

[valvo33]

I wonder does anyone posess a list of the component values used in the sinclair x10 I have a copy of the schematic which lists coponent numbers but not the actual values. I could probably have a fair go at making it work but why re-invent the wheel

regards steve

Manual post 2 seems to lists components.

This was the first introduction to class D amplifiers for me, back in 1965 as a student.

Thanks for the info iribeo

The x20 is obviously different from the x10 in as much as the x10 has a bridge output stage but the diag you have posted will give me a clue as to the square wave generator frequency and component values

I am just now building a replica of a sinclair micromatic radio but fortunately have the full diagram I intend to use bc549 transistors and 4 watch batteries to give around 5v instead of the 2.6 in the original obviously the bias resistors will have to be changed in value for silicon transistors as I think the MATS were probably germanium

all interesting nostalgia

I hope this helps. I built one in 1966 and it worked for years.
