I am looking at the schematic for my 1970's receiver and there is one type of capacitor it lists that I just can't figure out: SBL. I have searched many electronics places on the internet and there doesn't seem to be any mention of anything like that.
Maybe SBL is some brand? See attached photo. An example value is .0018(J) and I am pretty sure that (J) is a tolerance, I think 5%.
I guess I could open it up and take a photo of the actual capacitors if necessary.
Here's a possible hint. A different model receiver schematic from the same maker shows capacitors the same way, but has a table that calls them "BL ceramic"
Thanks
