I am looking for a BB205 Varicap, but so far have not

the given voltage range. FWIW, this is for the tuning circuit in an 80M

sounds like a euro part number. My guess is its in the 40-120pf range.
As a hack try a 1n4005 rectifier, they work ok as varicaps. Also the
collector base junction reverse biased of a 2n2219[and many other SI
transistors] is usable for that.
