TV Signal Amplifier

[cdonke]

As we can read in the image above, there is only on Trasistor (TR), but, at the schematic page smrtkit lists 3 transistors (BFR90, BFR91, BFW92).

I'm a newbie in electronics, and although I notice they are diferent, I can't understand what is this diference...

Datasheets:
BFR90
BFR91
BFw92

cdonke,

The circuit is not very critical, you can use which ever is the easiest for you to get of the listed.

[GPG1]

They will all work in this circuit. The layout is far more important

 

[InFLak]

I built this circuit. I think it is not very useful.

Wazzamatta with it?
It can't be any cheaper!
