New and Improved 2019
190 Watt M.O.P.A. Master
Oscillator Power Amplifier 1930's to 1950's Equipment Replica with
Updated Advanced Technology that Exceeds All Other Gas Tube Instruments.
New and Improved 2019 M.O.P.A. Amplifier (Master
Oscillator Power Amplifier) provides a variable 2.2 MHz to 3.8
MHz frequency oscillation with low frequency pulsation from the
GB-4000 function generator. This is a new and updated version of
the 1930-1950 MOPA original.
When connected to the GB-4000, the MOPA is capable of outputting 8
RF versus EM Systems
All gas tube instruments that are EM (electro-magnetic) do not
use RF (radio frequency) frequencies or an RF carrier
frequency. They use coils to produce a high electromagnetic
field to carry the frequencies to the target. Due to the fact
that they use EM to deliver the frequencies they are limited
to about 10,000 Hertz but a few go to 30,000 Hertz.Since
they do not use an RF carrier frequency it is almost impossible
to determine their power output.
For this reason almost none of these manufacturers list the
power output of their equipment. They generally are very good
instruments except for their limited frequency range. Anyone who
purchases the EM type of equipment should understand that they
only output low audio frequencies and have no RF carrier
frequency. All the original 1920s through the 1950s instruments
used RF and had an average power outputfrom
about 40 to about 200 watts.

New Improved 2018 M.O.P.A. Amplifier (for those
who already own a GB-4000) The M.O.P.A.
Amplifier is built to order for each customer, and shipped promptly. The plasma tube assembly is not included.
requires each M.O.P.A. purchaser to sign
and return a Purchaser's Agreement (which waives manufacturer's and
distributor's liability for improper use and any potential FCC or AM
radio interference issues. Void where Prohibited.)
