Can you do amplification without transistor and is it possible to design oscillator using diode?

Magnetic amplifiers and vacuum tubes don't need transistors to amplificate electricity current. You can get a transistor by two oppositely connected diodes.

Why transistor is so necessary?
Without the transistor you would need vacuum tubes to accomplish the same thing. None of our inexpensive portable electronics would be possible using vacuum tubes.
Why in oscillator triode is used instead of transistor?
I do not understand your question, oscillators CAN be built with either (and many other amplifying components). A few examples are:triode tubetetrode tubepentode tubebeam power tubepentagrid converter tube (cathode and first 2 grids form local oscillator)magnetron tubeklystron tubetraveling wave tubethyratron tubeneon lamppoint contact transistorjunction transistorsurface barrier transistorfield effect transistortunnel diodeunijunction transistorsilicon controlled rectifiermagnetic amplifierFERRACTORoperational amplifier ICtimer IClogic inverter ICetc.Perhaps you meant why it was in some specific circuitthat you don't give any reference to. If this is the case, I cannot answer without a reference to the specific circuit. One possibility for selecting a tube instead of a transistor to implement an oscillator would be that it must deliver higher power and/or voltage than a transistor is capable of.
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
How hartley oscillator produces a output waveform without input?
it uses the noise in air.
What is the difference between oscillator and multivibrators?
Oscillator is an electronic circuit which can generate oscillating sin signal without any oscillating input with use of positive feedback Multivibrator is a two stage RC coupled amplifier circuit which can generate squae signal without ac input
Without the devices such as hearing aids televisions and tape players would not be possible?

What device can give the output without taking any input?
its oscillator.....
How you can make a oscillator without using LC?
don't use LC

Has a pre amp acoustic guitar another sound without a amp than a normal acoustic guitar?
Usually there is no difference in sound, I play my Ovation electric/acoustic without amplification all the time, it sounds great.Some guitars, like Godin, make "acoustic guitars" that are meant to be played with amplification only, and are not loud enough without it.If you have a traditional acoustic electric you can play it with or without amplification, no problem.

How does a transistor act as a oscillator?
A: actually any active components will oscillate with positive feedback A transistor can be used as an amplifier along with an LC tank circuit to form an oscillator; it is an active device (as LIBURNO states) which will amplify the feedback signal coming out of the LC tank circuit. The tank circuit has a natural resonant frequency, meaning the L and C together will try to generate a specific frequency; this is then fed back into the input of the transistor amplifier, and the output is fed to the LC tank circuit exacerbating this oscillation until it reaches its' maximum level. An inverting amplifier can be used similarly; the output is fed to the input; this will cause the output to change as fast as the amplifier can. The frequency of this design is much harder to control, but potentially higher. Also, without the LC tank, the output voltage will remain lower.
What is the oscillator?
The purpose of an oscillator is to produce repetitive sound that will compliment the music being played. They are relatively easy to set up and use. Oscillators will filter the sounds providing a wide range of music.
Why you go for wien bridge oscillator?
It generates an oscillatory output signal without having any input source
