MAKE THE FOLLOWING CHANGES TO THE MANUAL OR ADD
NOTES TO THE TEXT TO REFER TO THIS ERRATA AT THE
APPROPRIATE PLACES
1. Page 28, left column, insert the following after the third checkbox step:
The NE602/SA602 integrated circuits (ICs) have been replaced by surface-mount RoHS
compliant SA612AD ICs. The SA612AD ICs are furnished pre-installed on tiny printed circuit "carrier"
boards that mount in the spaces originally provided for the 8-pin dual in-line (DIP) parts. The new parts
are supplied in ESD-safe bags marked SA612AD mounted on SMT1A. The re are three id en tical IC s, each
in a separate bag with the wire needed to mount them.
Locate three of the SA612AD mounted on SMT1A IC bags. Inside each bag is a length of wire, the IC on
small carrier board and an instruction sheet. Install the ICs as shown on the instruction sheet in the following
locations:
__ U1 __U2 __U7
2. Page 29, left column, third checkbox step: Delete U2, U7 and U1 from the list of pa rt s to install. They are
already installed.
3. Page 44, left column, fifth checkbox step: De lete the step and replace it with the following two steps:
Install 8-pin IC U9 (LT1252). Orient the IC as indicated by their component outlines.
Locate the remaining SA612AD mounted on SMT1A IC bag. Install the IC at location U8 as shown on the
instruction sheet.
4. Parts list, K1 Front Panel Board, Page 2: Delete the first sentence of the note at the bottom of the page.
Resistors on tapes are no longer available. See Identifying Resistors and RF Chokes on page 8 of the manual if
you need help reading the color codes.
5. Parts list, K1 RF Board, Page 2: Add note that the trimmer capacitors C13 and C20 may look different from
those shown.
6. Parts list, K1 RF Board, Page 6:
1) Change the description for U1, U2, U7, U8 to "
instruction sheet". Change the part number to:
2) Change the part number for X1-X6 to E850030 for a matched set of six crystals. The original part number
was for one crystal. A matched set is required.
SA612AD mounted on SMT1A carrier board with wire and
E850727.
