Best? Don't substitute. Worst? Substitute as you suggest replacing TTL with CMOS.

Substitution by experts in electronics requires some hours of research in many cases. Try your best to find the exact part or your project may suffer.

In the case of the 74HCT4066, use only a 74HCT4066 as that is TTL while the 4066 is an entirely different part.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

thanks
Ahh i see now ,it is a tll type 4066 i have found datasheet also now

in my goldpic3 i used hef4066bp cmos but its another case..he he
Happy New Year

where is STTH1210D in part list,,substituted with 1n4001 ?
and part list say 3 x 4700uF ,,but it dont mention the 10.000uF cap

i also think spes of 4066 and 4538 should be defined in part list
where ever it is a tll cmos .. or what 4066 ?
i will order to morrow parts from china..a priv contact she also have LF357..
i will buy several lf357 ..as they are hard to get in scandinavia
if yhere is any intresst of Lf357 i can order more and send..

Hello

Thank you Eugene. Good job!!! Clapp

I faced with 3 problems in your pasted documentation.
1) Where is main PCB file (bottom layer)?
2) Which P is 100 OHM? I couldn't find 100 OHM POT in part list.
3) I couldn't find STTH1210D on top over layer?
