Not exactly, but it strongly resembles the Ten Tec Model 150 
which is a commercial service SSB 100 watt transceiver for 
operation in the 2 to 12 Mhz range.  I believe the Model 150 
[and perhaps the '100] was Ten Tec's answer to the Kachina 
KC-100 transceiver of the same power and frequency range.  
Kachina produced the KC-100 and offspring for a couple 
decades or so.  My former company purchased many KC-100's 
and modified them for use as aircraft HF radios in many 
overseas countries.  I purchased a Ten Tec '150 for evaluation 
and still have it, virtually brand new.

Here are some excerpts from the '150 manual.  "The TEN-TEC 
Model 150 Transceiver is a medium power single sideband hf 
transceiver....."   "Model 150 provides full coverage between 2 
and 12 Mhz in four bands: 2 to 3, 3 to 5, 5 to 8 and 8 to 12 
Mhz.  Any channel may be operated on any frequency within the 
range without alteration or additional componets [except 
operation frequency crystal which was 12.7Mhz above the 
operating frequency -Lee ]. "  Also note that the '150 had a 
frequency selector switch with 8 positions, so you could 
operate any 8 crystal controlled frequencies in the 2 to 12 Mhz 
range.

The unit came in a variety of configurations.  Mine has both 
upper and lower sideband, VOX and noise blanker.   Sideband 
selection is made by switching crystal filters, each having a 
frequency of 12.7 Mhz, one upper sideband and the other 
lower.  The '150 sideband selection was much like the Drake 
TR-3/4 method but 12.7 Mhz instead of 9 Mhz.  Incidently, 
the Kachina also used the 12.7 Mhz IF and two filter method 
of sideband selection.

Looking at the schematic, Corsair heritage is obvious in the low 
level driver, the PA and the IF/Det systems. 

I don't have any idea how many of these things TT made but 
my '150 S/N is in the high 200's. 

Hope someone can shed some light on what the differences are 
between the '100 and '150.
