OO4780Boards


This a FEELER regarding a bulk-buy of etched/drilled PC boards for a paralleled LM4780 amplifier. The original design is discussed on this thread:

https://www.diyaudio.com/forums/showthread.php?s=&threadid=31220

The gameplan is to have the boards made as panellized pairs - each board will be 3.8" x 2.5" and hold TWO complete single-channel amplifiers. These can be paralleled for one bigger (240-watt) amp or run separate for 120-watt stereo.

The plan is to have the boards made as double-sided boards, with plated-through holes, solder masks, and silkscreened parts-position diagrams.

How the prices would break down if we reach certain totals, not including shipping:

20 panels - $20/panel (remember, each panel is TWO completely separate amps)
30 panels - $16/panel
40 panels - $14/panel
50 panels - $12/panel
75 panels - $10/panel
100 panels - $8/panel

Shipping will be based on sends from NW Florida, U.S. Folks outside the U.S. mainland will have higher shipping costs and international shipments will have their own unique costs/duties/annoyances, so plan accordingly.


If there's enough interest to spend the month of planning and work it'll take to pull this off, this list will become the order qty. So please post how many you're really willing to buy.


ADDITIONAL NOTE: This buy has been opened to another board, General Mayhem. (They're slightly bigger than diyAudio, but has a smaller base of members that'd be interested in this project.) Their totals will be added as a lump-sum.
