Many old amplifiers, so are my Yamaha B2 amplifier, have a connection terminal only for relatively thin speaker cables.
Speaker cables with banana plugs do not fit into these old treasures.
Quasi as an adapter I have now installed this Monster Flex Pins on the amplifier and can put the normal speaker banana plug into this. Even better hold the banana plugs, when the Flex Pin cuts a slice of black rubber back.
Also for fixing the speaker cable directly on Flex Pin this is done well, better than an alternative product that I have tried.
