If by Sprague 300 electrolytics, you mean 30D electrolytics,
there may be a few that are bad. I would guess about 5-10%
of all 30D's out in the field are bad by now.
The worst hit in the 30D family are the low voltage caps, 3V
and 6.3V, where I would guess 100% are bad by now.
I would suggest that rather than wholesale replacement, use
an ESR meter to look for obviously bad capacitors.
When a 30D type cap goes bad, it is very obvious, as it will
usually have dried out, causing its ESR to go from 1 or 2 ohms
to 100-200 ohms.

I would like to go back to my original question in my original post about any maint. issues such as changing out the original sprague 300 lytics and also if anyone has any spare parts for one?

Craig, I saw that one it's a bit steep for my budget right now was hoping someone had one for a bit less.
