You can now solder the 12 way connector, on the bottom of the
driver PCB. Then remove the tube PCB and all the screws and
spacers.
5.2 Low Voltage Generator components.
Fuse
D1, D2 (1N5819)
D3 (1N4148)
C1, C2 (220uF)
PWR (DC Socket)
L1(100uH Inductor)
IC1 (LM2576)
IC1 is a Surface Mount part, but it is large and easy to solder. Start
by wetting one pad with solder. Then place the part in position and
heat the lead so the solder below it melts and anchors the part.
The four other leads can then be soldered. Do not solder the
heatsink tab.
C1 and C2 are polarized. The Positive lead is the longest, and goes
in the pad marked ‘+’. The diodes are also polarized – the band on
the part must match the band marked on the white PCB marking.
