For r18 I get 2.2v and 4.9v

For r67 120ohm

For r59 75ohm

 

Only had a minute to look at thinga this morning. Maybe I'll take a deeper look again tonight. 

 

I had asked over at the retrosix discord and he said sounds like sync is missing. No image on composite and messed up image with rgb

 

 

Last one Luke and I did it was missing a resistor(someone worked on it prior, if you have oscilloscope, Luke and I documented proper times etc for clock, also remember Retrosix is in PAL country not NTSC but you are close) I should have read more carefully I thought RGB image was fine just not composite

@chrischuck I have a couple more things you could try to see if that may sheads any light on the issue in additin to the voltage both sides of R18...

 

With the Red meter lead in your primary meter input (Volts/Resistance) and the black lead in the COM input and the meter seting to Diode Test

Q1 Red lead to top Right pin (Base):

Black lead to top left pin (Emitter) = 0.67

Back lead to bottom pin (Collector) = 0.6

 

Q1 Black lead to top Right pin (Base):

Red lead to top left pin (Emitter) = 0.94

Red lead to bottom pin (Collector) = 0.71

 

Q6 Red lead to top Right pin (Base):

Black lead to top left pin (Emitter) = 1.29

Back lead to bottom pin (Collector) = 0.77

 

Q6 Black lead to top Right pin (Base):

Red lead to top left pin (Emitter) = 0.64

Red lead to bottom pin (Collector) = 0.67

@chrischuck  Did you ever fix your Jaguar?

 

I am currently experiencing video issues with my PAL Jag as outlined here:
