A.2.Comparison Of Various Models; A.3.Sb Series Vs Hw Series - Heathkit SB-10 Series Troubleshooting Manual

When used together, the SB-300 receiver and SB-400 transmitter could transceive and
had many other features of the S/Line, including crystal bandwidth filters and 1 kHz
tuning dial resolution. The S/Line influence was easy to see too, in its cabinet styling,
tuning mechanism and knobs. But by designing them as kits and using less expensive
construction, Heathkit could offer these units at much lower prices. The pair sold for
$590 that first year (equivalent to about $4100 today). The matching SB-200 linear
amplifier completed the line for 1965.
The following year, two more units were added: the SB-110 transceiver for the 6 meter
band, and the HA-14 "KW Compact", a linear amplifier based on the SB-200 but with an
external DC power supply, making it very small and usable in mobile service.

Heathkit announced the SB-100 five-band SSB transceiver.
Like the other transceivers of this time, the SB-100 (and later improved models SB-101
and SB-102) would become one of Heathkit's best selling amateur radio products. This
included a scaled-back, lower priced version of the SB-100 called the HW-100 (later the
HW-101) introduced in 1969.
In the next three years Heathkit brought out several more SB-series accessories,
including a kilowatt linear amplifier, the SB-220. The final model in the original SB-series
was the SB-303 receiver, a solid state replacement for the SB-301.
The SB-series would continue to be improved and sell well until 1974 and the arrival of
solid state and digital design, with the SB-104 transceiver, its accessories and a new
generation of amateur radio gear. Though somewhat redesigned physically it had a
similar appearance to the earlier SB-series generation.

a.3. SB Series vs HW series
The HW series can be thought of as a cost-reduced version of the SB series and they
share a number of components and design elements.
The most noticeable differences between the two series is the difference in cabinets,
front panels, and VFOs (LMOs).
The HW series uses a two part cabinet consisting of top and bottom pieces held
together with a series of screws. The SB series uses a one-part cabinet with a hinged
lid that permits access to the tubes and various controls, such as the VOX control, PA
