OK the postman’s been so this will be the plan
Instead of an integrated bridge 4 1N5400 diodes then a 25V 4700uF cap, a new LM338T in a bigger heat sink with R1 at 120 and R2 at 470. In the same box but instead of using the copper strip type board a chunky ‘whatever it’s called connector strip’ (see pic).
If need be the voltage out of the diodes should operate a PC PSU fan if things get warmish
Quick check – on circuit diagrams the diodes are shown as triangles with lines across one tip – I assume that would be the silver marked end on the ones in the pic?
