Old Schematics.
I have a RME DB-20 RF pre-amp that needs a schematic for me to check
against. This unit was made around 1938 and uses steel tubes. They were very popular during the war because they isolated the oscillators from putting anything back into the antenna for the enemy to zero in on. Mine is just for short wave listening and I have no continuity on the ground side of the antenna. If anyone can e-mail me a gif or pdf of the schematic I would be forever grateful. Thanks much, Bill Baka P.S. These had 3 tuned stages and 2 tubes worth of amplification so they were pretty good for their time. I only get about 10-15 dB now but it still helps. |
