4 leg capacitor in Saba Sabine radio
Hello,
I am wondering if I can replace this four leg capacitor ( rated 0.025uF) for two capacitors (same size)? Thanks in advance Diniz, Portugal |

The back cover makes no reference to the model, but I believe is Sabine M

Re: 4 leg capacitor in Saba radio
Looks like it is 'special' capacitor with an RF screen/shield, I've had a couple myself in German sets. I would check the extra earth wires aren't also used as ground points for other connections in the circuit, if not just stick a 22nF capacitor in there.
Let's see what others think as well. Andrew

Re: 4 leg capacitor in Saba radio
Yes I've come across these in a Philips radio. Mine only had three leads...the third being a screen. Usually found in places where hum pickup could be a problem. I replaced mine with a standard 0,01 but very carefully wrapped tinned copper wire around it for the length of the capacitor and then covered it with yellow heatshrink. Seemed to work fine.
