[ForSale-Swap] Correction

[Tom Evans, AG9X]

Usually capacitors of only a few pf are "gimmick" capacitors created
by twisting a few turns of insulated wire together.  The wire
insulation determines the voltage rating.  And no more than a handful
of turns is needed to create 2 to 3 pf

In the good old days
2 -10 pf = gimmick capacitor
10 - 680 pf = silver mica capacitor
0,0068 to 5.0 mfd = paper capacitor
10 to 1000 mfd = electrolytic

and mica capacitors are used for higher current and run from 100 pf to 0.01 mfd

The divisions are rough and this is from memory but sit hould give you the idea.

There is a similar range in variable capacitors running from ceramic
to air to vacuum.
