Strobonar 7 battery pack

<p>Hi, I couldn't find exactly what I was looking for so here I am. I have 2 very old Heiland "D" packs for my Strobonar 7, if anyone out there has any info, like a schematic of the guts, that would be great. And to be quite honest, even which way the battery pack goes in would be helpful. I put it back in the way it came out, and it looks right, but there are no markings to verify. The old vibrator capacitor doesnt work and while I can get a solid state replacement, I am unsure if it is positive or negative ground. As much as this will be a great addition to my collection of Honeywell/pentax stuff it would also be great if I could make it usable. Thanks in advance, Steve</p><div></div>
