Bill of Materials for: M.NATS Rev F-J "G1176" type 1176 Printed Circuit Board
There appears to be some confusion over which version of the 1176 project this BOM is for, even though it links directly from my G1176 page and the FAQ entry regarding the G1176. This page is for the current Rev J boards offered from my board sales post which are based on the Gyraf G1176. It uses "European" designation transistors and transformers as replacements to the originals suggested by Jakob and others. This BOM is not for the currently offered Revision F USA boards which use the original "American" designation transistors in the signal path and reproductions of the original transformers offered by Hairball Audio. The BOM for the Rev F USA boards is linked from the post above and from the 1176 Rev F - new board, new transformer! thread. For me, choosing components is half the fun. It does, however, require some thought. There are other, more specific BOMs created by others that list particular components and/or part numbers if you prefer to simply follow what others have done. Do a search. Lab member fucanay has kindly reformatted my crappy html table BOM and converted it to a PDF file.

Capacitor voltages as listed; if no designation refer to voltages present
in circuit (positive rail is 30 Volts so nothing fed from this rail could possibly
exceed this voltage).
The components listed here are primarily parts that go onto the boards
and should not be construed as a complete list of parts to build a
finished 1176 clone. You will need to supply an appropriate AC power
transformer, a VU meter and case, knobs etc to finish your clone.
