Guitar,

you need not solder the collector / case of a TO-3!

Invest in some clean free solder flux.

Rudi_Ratlos · 30th September 2011, 05:04 PM

No - I won't.

I rather invest in 100ml of ISOPROPANOL 70 and use my old tooth-brush - which is much cheaper!

I don't think ISOPROPANOL 70 will fix those solder joints.
