Originally released in 1958, the 299 was the first of Scott's "Stereomaster" range. It was characterized by a 'sweet sound', classic styling and became Scott's most successful integrated stereo amplifier.

The earliest version (299-A) retailed in 1958 for $200 and had an output of 17 watts per channel (RMS). It utilised eleven tubes: 4 x 12AX7, 2 x 6BL8 (floating paraphase inverter w/AC balance pots); 4 x 7189 (output) and a 5AR rectifier. Unique to the 299 range were the three neon 'Christmas tree' function indicator lights to signify different modes of operation as selected via the mono/stereo function selector switch. Another unique feature was the bias control adjustment common to both channels.

The 299-B (1960-1961) had a slightly increased output (21 watts per channel) and retailed for $210. New phase splitters (6U8/6GHG) replaced the 6BL8's and larger transformers were employed. Minor styling changes were made to control knobs, indicators and logo/lettering, a new double-H, logo replacing the traditional green oval logo.

Output was again boosted for the 299-C (1961-1964) with 32 watts per channel (RMS) although later versions had smaller transformers and only produced 28 watts.
The amplifier was upgraded using the older LK-72 (kit) circuit with 7591 output tubes and a front-panel headphone jack installed to meet current trends.

The final variant (299-D) was introduced in 1964 with 34 watts per channel and a price tag of $235. Improvements included new output transformers (TRA-8-5-4) and an extruded front panel re-styling.

Today's market value ranges from around $250 for shabby but functioning examples to $600 plus for ones in mint condition.
