Description: I MAKE THESE TO ORDER, SO PLEASE ALLOW ABOUT 20 BUSINESS DAYS FOR SHIPMENT, ONCE ORDERED. MODERN DAY VERSION OF THE BRITISH MK XV SPY RADIO FROM WWII. THE CIRCUIT EMPLOYS THREE 12SK7 PENTODE TUBES. THE ORIGINAL 1943 CIRCUIT USED THE 6 VOLT, 6SK7'S. THE FREQUENCY COVERAGE FOR THIS VERSION OF THE MK XV BEGINS JUST BELOW THE 80 HAM BAND, WITH CONTINUOUS COVERAGE TO ABOUT 13.5 MHZ, MADE POSSIBLE BY PLUG-IN MICRO INDUCTORS. YOU WILL NEED AN EXTERNAL 12 VOLT DC POWER SOURCE OF AT LEAST 1/2 AMP CURRENT CAPABILITY, PLUS 4 OF THE 9 VOLT BATTERIES, AS SHOWN IN THE PHOTOS (BATTERIES NOT INCLUDED IN THIS LISTING). THIS RADIO REQUIRES A HI-Z INDUCTIVE (2 TO 4K OHMS) OR PIEZO HEADSET. HEADPHONES ARE NOT INCLUDED FOR THIS LISTING. THE RADIO HAS MAIN AND FINE TUNING, REGEN, ANTENNA COUPLING AND RF GAIN CONTROLS, ALL ON THE FRONT PANEL. YOU'LL NEED A WIRE ANTENNA OF AT LEAST 25 TO 50FT IN LENGTH, ALONG WITH A GOOD EARTH GROUND. A 75 TO 100 LENGTH ANTENNA WILL PERFORM BEST ON THE LOWER FREQUENCIES. AS STATED, AN ANTENNA COUPLING CONTROL IS PROVIDED FOR ADJUSTING TO DIFFERENT ANTENNA LENGTHS. 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. AGAIN, THE RADIO WILL BE CONSTRUCTED WHEN ORDERED. YOU WILL RECEIVE EITHER GOOD USED OR NOS VACUUM TUBES. ALL OTHER PARTS, INCLUDING THE 3D PRINTED CHASSIS, ARE NEW PRODUCTS. **********SHIPPING TO THE UNITED STATES ONLY*********
