General purpose solder.
Easy to work with.
Good for trained and professional repairers alike, and will easily provide good results even for the not-so trained DIY’er.
Composition: Tin/Lead Sn60Pb40 with Colophonium
Sold here in lengths of 2m.
2 meters will be enough for most Beoparts-shop capacitor kits, service kits and most other discrete vintage repair jobs.
Note: Does not contain copper, so not particularly suitable for repairs to very modern (RoHs) products.
