* If you are using a single phase wall wart supply, then fuseholder F1 and its associating fuse does
not need to be fitted. F2's fuse rating should then be a 1A antisurge or time lag type. If you are using
an internal transformer or split output line lump supply then both fuseholders are fitted and the fuses
are both 800mA antisurge or time lag types.
2 off TO-220 insulator

2 off TO-220 insulating bush
For mounting of U1 and U2 to panel
Heatsink paste

Mounting hardware for the four mounting holes. For the Bryant Broadcast or Holt Broadcast 1U
aluminium “Joggle” cases the following hardware can be used.
M3 hex threaded 6mm spacers (4 off)
M3 CSK 16mm screws (4 off)
M3 hex nut (4 off)
M3 shakeproof washers (8 off)
M3 flat washers (4 off)
The shakeproof washers go between the bottom panel and the hex spacer, and between the flat
washer and the top nut. The flat washer goes up against the top surface of the PCB.
For mounting the power devices, U1 and U2, you will also need the following parts.
M3 10mm screws (2 off)
M3 hex nut (2 off)
M3 shakeproof washers (2 off)
A shim plate may also be required if the lower panel of your case is particularly thin and you wish
to use countersunk screws.
