Ward-Beck transformers
Ward-Beck designed and drew its own audio transformers. The type numbers are a family code: 60-n input, 70-n output and 80-n power transformers. Many of the early drawings (1966–68) are drawn or checked by RB (Rodger Beck). Each entry shows the drawing(s), the date on the title block, and the modules the type is used in (from parts lists, filed drawings and manuals).
