1625 PENTODE TUBE SHORTWAVE REGEN RADIO (APPROX. 3.55 TO 14.15 MHZ)

Description

I MAKE THESE TO ORDER, SO PLEASE ALLOW 7 TO 10 DAYS FOR SHIPMENT.
THIS IS THE OLD TRADITIONAL STYLE OPEN FRAME 1625 SHORTWAVE REGEN RADIO RECEIVER. THE PHOTO SHOWS THE 19BG6G TUBE ON THE CHASSIS. EXCEPT FOR THE FILAMENT VOLTAGE THE 1625 IS VIRTUALLY IDENTICAL TO THE 807, 6BG6, 19BG6, ETC. SEE PHOTO #6 WITH A 1625 AND 19BG6G SIDE BY SIDE.
THE COVERAGE IS CONTINUOUS FROM ABOUT 3.55 TO  14.150 MHZ. THERE ARE NO PLUG-IN COILS TO CHANGE.  AS A BONUS I HAVE ADDED A ONE STAGE TRANSISTOR HEADPHONE AMPLIFIER, WHICH INCREASES THE VOLUME CONSIDERABLY. THE TRANSISTOR AMP IS PART OF THE CIRCUITRY, AND RUNS OFF THE COMMON DC FILAMENT/B+ LINE.
THIS RADIO WILL WORK WITH A HIGH IMPEDANCE 2 TO 4K OHMS INDUCTIVE TYPE HEADSET, AND ALSO WITH HEADPHONES THAT HAVE PIEZO ELEMENTS (NO HEADPHONES INCLUDED IN THIS LISTING).
A WELL FILTERED 12 TO 14 VOLT DC POWER SUPPLY (OR BATTERIES) IS REQUIRED TO RUN THIS RADIO (NO POWER SOURCE IS INCLUDED). I FIND THE 12 VOLT CORDLESS DRILL BATTERIES MAKE AN EXCELLENT POWER SUPPLY FOR THIS TYPE OF RADIO.
THIS CIRCUIT HAS MAIN, FINE TUNING AND REGEN CONTROLS ON THE FRONT PANEL. SINCE THIS IS AN OPEN CHASSIS WITH NO SHIELDING YOU MAY GET SOME HAND CAPACITY EFFECT, BUT MORE SO IN THE HIGHER FREQUENCIES. A GOOD EARTH GROUND WILL HELP TO MINIMIZE THE HAND CAPACITY EFFECT.
YOU'LL NEED A WIRE ANTENNA OF AT LEAST 50FT TO 100 FT. IN LENGTH, ALONG WITH A GOOD EARTH GROUND.
I GUARANTEE THIS RADIO WILL WORK IF YOU HOOK IT UP PROPERLY. I WILL INCLUDE A HAND SKETCHED SCHEMATIC DIAGRAM OF THE CIRCUIT, PLUS A BLOCK DIAGRAM SHOWING WHERE TO HOOK THE ANTENNA, HEADPHONES, POWER, ETC.
THE RADIO WILL BE CONSTRUCTED WHEN ORDERED, BUT SINCE THE 1625 TUBE AND A LIMITED NUMBER OF OTHER PARTS ARE USED, I'M LISTING IT AS A USED ITEM. BETTER THAN 80% OF THE PARTS ARE NEW OR NOS.
