4 days ago i have only changed both 2n3905 , integrator caps and socket of both 34001, but the problem not resolved...at this point i have to replace socket of other remain chips, or i reball solder points of it....
It's the finger issue a very mystic problem. i have tested both 34001 with new, but not resolve.
If i put totally finger on top of 34001 all vectors going out to top right corner of screen and when i remove finger it return slowely in correct position!
Question, the little compensator capacitors 10nF (104) from power line 5v and gnd instslled to all chips, can it cause this type of problem (finger problem)?
