Much cheaper alternative to Mouser as a source for capacitors, especially Canadians with extra shipping charges is Ebay (ships from Hong Kong to Ontario in about 25 days).
I ordered three capacitor types from Ebay, shipping included, as follows in Canadian $ (US$ would be less):
ITEM PRICE: C $1.79 20PCS 50V 10uF Electrolytic Capacitor 5×11 Radial (Used this for C7, C8, C13) ITEM PRICE: C $1.79 20PCS 35V 100uF Electrolytic Capacitor 6×7 Radial (Used for C11) ITEM PRICE: C $2.31 10PCS 400V 10uF Electrolytic Capacitor 10mm×13mm Radial (Used for C3)
I repaired two 2413S PLM's, one older version V1.0 using the tack soldered capacitor/wire/coil combination and one newer PLM V1.B and also one 2443 Access Point V2.6. All three devices are functional now.
Followup: As per valid comments from other forum members, a better choice for longevity of repairs for C7, C8, C13 might be an ultra low impedance ESR type such as 10pcs 10uF 35V Rubycon ZA 5x5mm 35V10uF Low Impedance Electrolytic Capacitor for a buck including shipping.
