Thank you, you guys are great!

You can just short the outer pins of the filters on SCB7 to make it work again and maybe eventually you can find suitable replacement parts to restore visual condition.
Good to know. I was thinking about a temporary fix like that too, but wasn't sure whether I'd fry something if I just bridge these pins.

If the capacitor footprint on GUS is one of those small orange ones it'll be a 0.1µF radial ceramic capacitor. It is quite unlikely the capacitor plays a critical role as most are simply power supply bypass ones and lack of one or two won't make a difference in operation. I was unable to see on photos where the C19 is though...
Yeah, one of the small orange, radial ceramic ones. I attached some photos. Maybe I'll just put the card in and see whether it operates normally or behaves funky...

TDK's ACF451832-103-TD01 is a suitable filter replacement for those missing on the SCB-7.
I performed a similar repair on an SCB-55 several years ago:
Fantastic, thank you! I think I came across this part during my research but for some reason scrolled over it... Now I'll just have to find a supplier that will sell in household, not industrial-sized batches, and that won't charge me an arm and a leg for shipping. Duh...
EDIT:
Here's a datasheet that could match the capacitor: https://www.datasheetarchive.com/pdf/download … 520K5R%2520104K
K5R on the ceramic capacitor seems to decode to:
K - Capacity Tolerance +/- 10%
5 - Rated Voltage 5-50V
R - Dielectric X7R (Stable)
562 would then, according to the datasheet, be 5600pF = 0.0056µF = 5.6nF
But I might be wrong...
