NOTE: All serial numbers and dates quoted are approximate only. Dates quoted
are time of manufacture. Exact date and serial number of Mk changeover cannot
be guaranteed.
Mk1
April 1990 through September 1994
Serial numbers 5629 through 6753
BJT input transistors
Most are wired with Furakawa input and output cables
Some are wired with Kimber input and output cables
U shaped chassis design
Not up-gradable to Mk2
Identified as Mk1 by checking for a non-removable base and a lack of countersunk screws
on rear panel
Mk2
January 1994 through April 1998
Serial numbers 6397 through 8299
JFET input transistors
Most are wired with original Siltec input and output cables
H chassis design
Changed from 4 heatsinks per side to 5 midway through production life cycle
Up-gradable to Mk3 (if long chassis with 5 heatsinks per side)
Single Transformer
Identified as Mk2 by checking for a single power transformer and six countersunk screws
on rear panel
Mk3
April 1998 through October 2001
Serial numbers 8299 through 0836
Same circuit board set as Mk2
All wired in generation three (G3) Siltec input and output cables
Ground lift switch fitted to Mk3 midway through production life cycle
Two transformers (paralleled - not configured as dual mono)
Identified as Mk3 by checking for twin power transformers or Mk3 designation on rear
panel
NOTE: The SA102 is a new product, and no SA100 can be upgraded to SA102
specification.
