Quick Answer
Amplifiers Kits are panel trainers for electronics practicals on transistor and FET amplifiers, with the components on the front panel and test points brought out on terminals. They cover common base, common emitter and common collector studies, negative feedback, BJT biasing, class B push-pull output, two-stage RC coupling, an RC coupled trainer with two inbuilt AC millivoltmeters and a FET common source amplifier. JLab lists 7 of these trainers here.

Frequently Asked Questions
Which bias circuits can be set up on the Biasing of Transistor BJT trainer?
Fixed bias, collector-to-base bias, emitter resistor bias and voltage divider bias, using one NPN transistor, internally connected resistances brought out on terminals and two meters for voltage and current.
Do the amplifier trainers come with a signal generator or millivoltmeter?
The RC Coupled with Inbuilt Two AC Millivoltmeter trainer has its own power supply and two AC millivoltmeters. For the Study of Transistor Amplifier Circuits, FET Common Source Amplifier and two-stage RC coupled trainers, the function generator, millivoltmeter, VTVM or CRO is an optional instrument and is not included.
