Vintage Synth Repair

Nick-
I believe it's just a symbol to indicate an electrolytic. I don't think the direction of the lines implies anything beyond artistic license. If the polarity isn't marked it's probably safe to assume that it's non-polarized. You can check to see if one lead or another is tied to a ground trace (but if it's a filter cap on a negative voltage supply, the (+) side is at ground.)

      This is def going to seem a bit of a dumb question but I am just trying to identify the polarity of some old electrolytic caps I am replacing. The old ones don't have any markings, they just have most of the writing on one side. On the board the symbol is marked as per my attachment but without the + & - that I have added.
 Can someone tell me please if I am correct with my polarity markings or not! Internet image search for old cap symbols just comes up with something similar but the slope of the lines in the middle go the other way (they go up from left to right instead & indicate + on the right). Confused!
Thanks
