All non-insulated transistors should be insulated with a mica or sil pad and an isolation washer .... You can get away without one if there is no way the heatsink will come in contact with ground ......

Can someone advise on the correct way to solder the kind of voltage regulators found in amps ? ie; TDA 2050. Some suggest earthing the body to ground and then there is the question of the correct soldering iron temp.

Hi Minion,
Mate,, great effort :tu: Just looked at the pics. Wow a lot of work in that one so glad you got it all working.
Forgot the ground ay? Yep been there a few times.
The ground is always the wire you forget to add :grr
One little thing,,, if I may be allowed?
Do I see Wires passing through holes with no grommets and around sharp metal edges?
can be an issue down the track. :trouble
Cheers, Phil.
