AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..Also, i had the idea to integrate HDMI out at some point, im looking for suitable IC's for that that can take the RGB+sync signal and...

AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..yeah man! so, indeed CL26 will be added, probably around 3nF, vertical image size right now is barely adjustable so ill find the cause...

AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..GOOD NEWS! Thanks to mark_W, i found that i had the wrong value for DL1, the zener diode that protects in case of over voltage...

AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..Thanks very much, well i have checked the other voltages, and they are all within spec, so that is good, ii trace down C-sync as well...

AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..So have 75V on the QL1, it is stable, oddly enough this is without the VGA mod in place, so it should be 60V or so. all other voltages...

AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..okay now i have checked the board one more time, and i cannot see any errors there anymore, i did fix 2 connections before, now i have...

AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..Yeah, i know that as well, it seems complex as i have also used some cross-reference parts for several things, such as QL2, some diodes...

AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..still working on this, it seems my 60V is always too high at 80+V , the other voltages are in check, at 8 and 24V. quite strange to me...
-
AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..Now i got all the voltages dialed in, i got the +5 / +12 / +8 / +24 / +60V / -5 all stable under load, but i still have a voltage drop...
-
AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..Okay, i have +5 and +12 aswell now, but when powering on, and when it's time to turn on the CRT i can see from my AC power meter it's...

AArjenCNX replied to the thread Color Classic analog board re-design, needs community feedback..Yeah, you got that right! so the HV supply switchmode is working, the +5 +12V one isnt starting through the power on command from the...
