Output capacitors C 2 and C 4 are required to stabilize regulators. Values can be 1 MFD min. tantalum or 10 MFD min. electrolytic, 20V min.
LM-338 is an adjustable regulator and MFR’s specifications (National Semiconductor) should be consulted for values of external components.
All ICs are National Semiconductor types.
All bridges are EDI types.
