Hi Roger,

i did not yet try this valve design from Burkhard, however his designs are preforming in most cases very good.
I tried it with other valve audions, however i never got more than 10 dB of SNR. The basic problems of the audions is the frequency stability and tuning. You must be very careful when building the coil.
Just try it out for fun and donot be dissapointed, when it does not work as you expect. At least for AM it is working quite well ;-)

you find much more audion designs using all types of valves.

I'm building and experimenting with PCF802 (http://users.triera.net/zupanbra/elektronke/pcf802.html)
I'll report about results!

Hi Saulius

Thanks for posting the links - I've never seen a breadboard for valve technology before!
