One pair of 1950's Bozak N103 crossover networks. These are from my 35 year old "Abyss of Stuff I Never Got Around To" and are untested. As such they are offered for sale in as-is, as-pictured condition for parts, repair or restoration. There is damage to one mounting board so please look at the pictures before buying.

I can probably scare up a quad of B207A if you want to build your own Bozak 305. You're on your own to get the mid driver but that's the easiest part of this equation. The price will be prevailing eBay pricing for the B207A - whatever that is these days.
