Have the money, ready to buy at right price. made a BIG mistake selling mine.

You can try your luck on CL, with the due caution. There were 3 or 4 recently, they'll come up again.

Here is a vintage one from eBay
http://www.ebay.com/itm/Vintage-Alembic-F-1X-Tube-Pre-Amp-new-tube-Bass-preamp-F-1X-amplifier-/311361777985?pt=LH_DefaultDomain_0&hash=item487e9bb141

I sold the first 70s era F2-B I had and soon realized what a big mistake that was. Luckily I found another one and will never make the same mistake again.
 
I see FX-1s listed for sale all the time you shouldn't have a hard time finding a replacement. Good Luck in your search!

Thanks guys, the NOLA guy will not ship and I am hesitant to purchase the vintage one without the top plate. I am still looking though.

Got one on ebay....thank you.
