REG TUBE SCHEMATIC
UN RECEPTOR SIMPLU CU TUBURI DIN CATEGORIA CELOR CU REACTIE. STABIL SI CU O RECEPTIE FOARTE BUNA. PRIMUL TUB CARE ERA AMP. DE ANTENA NU L-AM MAI TRECUT PTR CA NU MAI ERA NEVOIE. TOATE BOBINAJELE SE FAC IN ACELASI SENS. DACA NU APARE REACTIA SE INVERSEAZA CAPETELE BOBINEI L3 !!!!
A SIMPLE TUBE RECEIVER IN THE CATEGORY OF REG. STABLE AND WITH A VERY GOOD RECEPTION. THE FIRST WAS TUBE AMP. I'VE EXCLUDED, YOU NO LONGER NEED. ALL CYLINDRICAL WINDINGS ARE MADE IN THE SAME WAY. IF YOU DON'T SEE The REACTION REVERSES The ENDS Of The COIL L3!

80m reg receiver with vaccum tubes
and two 6j51p svetlana.one is for the detection,and the other tube for arf, but it may be missing.!!! It's built for 80 meters
I would like to mention that the sound produced by the tubes can not compare with anything else, you give the right sweet, melodious and warm. It is very pleasant to the ear
