<div>== C9 Main Board Capacitor ==<br />
<br />
Can I double check the C9 value on this list? I have an Issue 4 BBC Model B. C9 on the board looks like a 10uF.<br />
<br />
When I look at Power supply C9 looks like the 220uF?<br />
<br />
Because I have a low -5V (I am measuring -4.37V) I am assuming that this is linked to my current problems. Boots and runs normally from cold for 5 minutes than crashes. Fails to restart until completely cold (or capacitors discharged???)<br />
<br />
I dont have much experience in all of this so any clarifaction welcomed.<br />
<br />

By the way great article.... thanks Mike [[Special:Contributions/2A01:CB00:8118:5500:E84E:45F0:E1A4:C4B|2A01:CB00:8118:5500:E84E:45F0:E1A4:C4B]] 09:36, 13 December 2025 (GMT)</div>2A01:CB00:8118:5500:E84E:45F0:E1A4:C4B
