Hartley or Colpitts oscillator

I need Hartley oscillator or Colpitts oscillator. I tried a lot but failed. I am simulating circuits on multisim but not been able to get sine wave. Can anybody help me with that??
I am using these oscillators because I want high power oscillator in high frequency range.

Why don’t you make a low power oscillator and amplify the signal with an AB 500 watt amplifier.

Dear, I there is a link of data sheet of a transistor and its Typical frequency is 30MHz. What is meant by "typical frequency"??

2nd this is about op amps. I need a analogue devices op amp. which part you will suggest??
Typical frequency in this case is the harmonic oscillator like in this flyback circuit.

As for op amps:

MCP601 1 op amp MCP606, TL091

MCP602 2 op amp MCP607, TL092

MCP604 4 op amp MCP609, TL094

LMxxx series

108-208-308 1 op amp IC

158-258-358 2 op amp IC

124-224-324 4 op amp IC

That's What i am doing it now.
Just Google

Crystal oscillator circuit

Sine wave oscillator circuit

Crystal sine wave oscillator circuit

You will get thousands of basic oscillator designs you will need to tweak.

Then Google

Power amplifier circuit

AB amplifier circuit

500 watt ab amplifier circuit

You will get thousands of circuits from 1 watt to over 5000 watts from 6 volts to 600 volts.

Yes, I already have a power amplifier circuit and it is pretty good I just need NPN and PNP transistor with HIGH POWER AND HIGH SPEED.

I hope you could help me with that.
These are complementary transistors.
2SA1943 and 2SC5200 230 Volts 15 Amp 150 Watt 30 MHz

It worked thanks.
How much maximum frequency and maximum power we can get from an amplifier. I mean what is the latest technology about amplifier.
Public ICs or private ICs the biggest problem is everything is not public then the manufactures use alphanumeric reference and not properties based references. When I look for a transistor in a data book of transistors I get 2N3904.when I look in my filing system I see watts, then volts, then hurts, then complementary. Manufactures don’t do that so you ether know where to look or you are screwed, the transistors I referenced you I have in my stock of parts so I only looked in my filing system, watts, volts, hurts, complementary, not alphanumeric.

Suppose I found a transistor with 100W power, What does it mean? how much amperes it can handle.
