Default Re: should this work?

The reason for the transistor oscillator is simple. It's the only device which i got to work so far. Attempts at building a valve xtal oscillator failed so far.

The osc is there, on a pcb, and i know it definetly works. It also runs comfortably from rectified 6.3v.

Now i m trying to at least build a working valve RF amp.

My ultimate goal is to build a micro power 1MHz transmitter so i can stream music from my laptop to AM radios in my shed or kitchen. At the moment i'm using a single transistor FM tx, which works, but some of the older radios i like dont have FM.

However, to build it, i need a working valve rf amp. I dont mind using the transistor oscillator, since it will juts happily run off the heater line with a full wave rect. I'm then planning on modulating it by varying the screen voltage.
