[Heathkit] FS or Trade - SB-104 Noise Blanker

[Shawn Duley]

I recently picked up another SB-303 with what I believe is an SB-104
noise blanker.  Actually a pretty slick
installation with only one hole drilled in the chasiss and the on/off
line wired to a spare phono socked and a slide switch plugged into the
socket.

I intend to remove the noise blanker and offer it for sale or trade.
It's dusty but appears to be working.  Since I have no documentation, I
can't be sure.  Heath part number on the card is 85-1412-3.  I need a
crystal pack for an SB-303 (same for the SB-401), or at least the top 4
band xtals.  36.895, 37.395, 37.895, 38.395 Mhz.  Mine are either way
out of spec or dead.

Could also use an HW-104 extender card.

I've seen one of these noise blankers on ebay, but didn't pay a lot of
attention to the price.  Will consider reasonable offers to buy or
trade.
