Hello everybody,
This is my first post here but i read this site for many months. I’m an enthusiast DIY-er but with no knowledge of designing schemes. I wonder if you could help me.
I want to build something simple with tubes, just for fun, a radio retro in 20’s style. I have parts from an old pick-up Tesla Suprafon: exit transf, a couple of ECL82 – russian equivalents, a penthode EF184 and power transf. with ~165 V c.a. for anodic and 6.3 V for filaments.
I have two possibilities:
a) 1V2 – EF184-germanium diode-ECL82 or
b) 1V2 – 1’st (L)82 as rf. ampli.-1’st (C)82-tide as a diode for detection-2’nd ECL82 as AAF.
Audio power no more than 1W.
Can anybody help me and do the design?
I’m not a rich tube guy but I can share with you some pictures of a 50 years old german marvel – Strassfurt 600 - http://www.elforum.ro/viewtopic.php?t=26263
Thanks in advance!
Please excuse my bad English!
