Heathkit W-6M
Little is documented about the Heathkit W-6M. What survives is essentially Heathkit's own 1958 advertising campaign — no independent technical review, no service manual, and no production figures have made it into the archive.
The W-6M was a 70-watt high fidelity amplifier kit, priced at $109.95. Heathkit's ad spread in High Fidelity (July 1958, p.30) paired it with the 25-watt W-5M at $59.75, presenting the W-6M as the higher-power choice as hi-fi systems grew more demanding. The same campaign appeared across mid-1958 issues of other audio magazines, so the model was certainly on the market that year.
Beyond the power rating and kit price, the record goes quiet. No frequency response, distortion figures, tube complement, dimensions, or production years are documented in available sources.
