"LOOK MA- NO HIGH VOLTAGE" 40 METER "PRACTICE OSCILLATOR" KIT.

Our little 12K5 tube crystal controlled oscillator was
designed for 40 meter code CW operation. It was first
published in CQ magazine in 2006. The output is less than
1/8 watt. It can be used to send cw code to a close by
receiver. Or code practice oscillator. Or marker signal.
You get a complete instruction manual with assembly,
wiring, testing, soldering and construction tips. Kit includes
NOS tested vintage 12volt 12K5 tube. Supplied with kit is
40 meter crystal, mini tuning capacitor, tube socket, clips,
and a coil form with winding instructions, and a spare coil
form for experimentation. You supply a 12 VDC at 1 amp
min power supply, key and dummy load.
Lots of assembling and testing practice. And it won't break
the bank.
