[Heathkit] SBA-1400-4 power supply

[Tom Chesek]

I recently acquired one of these power supplies and am looking for a copy of the Heathkit manual.  It is supposed to be essentially the same supply as the Yaesu FP-757HD.  I do have an electronic copy of the Yaesu user manual which is a two-pager covering basic use and a schematic but I wondered if the Heath documentation provided a parts listing/layout and circuit description.  Heath used this with the SB-1400 HF Transceiver which was also made by Yaesu and not in a kit form.
