Just a power supply question the 120v psu do they use the sam capacitor on the low voltage side as the 240v ones

DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

Re: Mitsumi 68-4242a
What is the difference between the SR97 and SR98 PSU for the Atari ST/STF/STFM/STE? I know in the USA, the SR97 PSU is used for 120V Atari ST.
Is the SR98 the 240V model for Europe?
I recapped my SR97 and replaced the Bridge Rectifier. However, Mr Koda at Best-Electronics in San Jose, California, USA told me I should also replace the power resistors. I can not find a schematic for the SR97 PSU, but I did get a schematic for the SR98 PSU.
I noticed the model on the PCB on both the SR97 and the SR98 the number 68-4242A.
If I am correct, the SR97 and SR98 should have different component values depending on whether the model is for 120 V (USA) or 240V (Europe). Or are the component values the same for both?
Thank you.
