Audiolabyrinth, if you have an amplifier, tube or solid state, with a 100KOhm input impedance, any preamp tube or solid state will work with it. The general rule of thumb is that the source have an output impedance that is no more than 1/10th of the value of the load.

Input impedance varies considerably with the circuit configuration shown in Figure below. It also varies with biasing. Not considered here, the input impedance is complex and varies with frequency. For the common-emitter and common-collector, it is base resistance times β. The base resistance can be both internal and external to the transistor.
