hi, have here a valiant ii transmitter without the crystal dummy knob,
to cover the crystal holder,
now in the hole someone put a 6,3 audio female audio plug,
thas can easely removed, deeper a see a radio tube socket, seems to be
original,
question, how do you put the cristals in place,
is there somthing to plugin in the tube socket,
what parts most be present to work with the crystals,
can you change crystals from the frontpanel hole labeled crystals
thanks carlos




You can plug 2 of the old FT-243 style crystals into an octal
socket. You will have to look in the manual for the proper
orientation.

Hi,

You can also use two type HC-17/U fundamental mode crystals
in the octal socket. You should specify 32pF load capacitance
when you order them. Most crystal suppliers no longer offer
crystals in the old FT-243 holders.

The type HC-17/U holder is the same as the modern, hermetic,
HC-6/U holder, but has thicker pins to mate with the sockets
that were used with FT-243 crystals.

The crystals take the place of the VFO, whose output frequencies
were multiplied to get to the higher bands.
So if you want a crystal to operate on 14,200 , 21,300 or 28,400
you would plug in a 7,100 KHz crystal.

The manual has the chart of which crystals to use
for the desired band.
