BBE AM64 American Metal

I wasn't aware that BBE would release nice, simple designs with all through-hole components for good bargain prices. Funny how all the units on eBay are priced about a double of the original unit as a new...

The input cap (4n7) could be upped to at least 22n and there are other things one could do to this too. Clipping on a switch and so on. You won't be saving any money building this though... The power filter cap is 1000µF in the original unit, but i left it at 220µ for this layout. Both of those values are a overkill. You'd be fine with 47µ or 100µ in its place.

  2. Hi Mirosol, this is verified. I have a confession though. After a Xmas celebratory weekend out (Sun/ Sat) I came in turned on the PC and started to build what I thought was a Proco Rat 2. Next monring not remembering any of it found this half made board sitting on my workbench. Discovering it was actually this I thought it best finished off. Made up for where I failed on the Arion metal anyway. Sound wise - good sustain and tone and plenty of gain. Although got safty sake dont try to build this one after a xmas night out lol.

  3. Sorry one last thing I subed the 330pf for a 380pf, dont know what effect it had but it was all I had and it sounds fine, no clips, quiet spots or anything to report.

    1. Great to hear Jim! I stopped building drunk a long ago :P I mean, who hasn't built at least one circuit completely shitfaced? :)

      The 330p/380p is there to tame the high pitch noise that may occur without that cap, so 380p is a very good substitute. You would have been fine with 470p too.

      Thanks for verifying. I'll tag it right away.

  5. Built this and like it a lot. Had no issues with it, nice easy build The tonal variation is great. Messed with different LEDs but red seemed best.
