[Amps] Still yet another interesting SS amp

#######Too bad henry radio stopped selling their  35 / 50 /100 watt pads, 
that could be bought in  anything from
                I think 1-10 db, in 1 db increments.

They are on EBay. Bought a 3 and 4 db 100 watt unit a few weeks ago.

This is the latest german made  SS amp, fully built.
Reinhard DH3NAB will be at Xenia with
demo units.  Booth 6506 in Bldg 6.

http://rf-kit.de/en/

It uses a pair of  LDMOS devices...which can be
BLF188XR;    BLF578;    MRFE6VP61K25

2.5 kw out.  Auto tuner.   The end user no longer has to supply his
own set of LP filters.  They now supply the  heavy duty LP filters.
160-6 m.... including 30, 17, 12m.   Aprx  $3k.

1.5 watts of drive =  1.5 kw out.
3 watts of drive  = 2.5 kw out.

Also comes with built in switching supply.   With the low  drive 
requirements
on these latest SS amps, you really dont require any more than a 10 watt 
xcvr,
then just add whatever final pa  power level external amp you desire, for 
your application.

Have fun trying to get 1.5 watts out of your typ  100-200 watt xcvr.   Heck, 
even the 11m ops,
with their  5 w cxr ... 20-25 w pep out cb rigs will be able to drive the 
crap out of any of these
SS amps.   20-25 watts was ample to drive the palstar, qro, etc, amps with 
the 2 x 4CX-800 /  GU-84B
flat out.

Even the ameritron AL-600  can be driven with as little as 7.5 watts...after 
the oem attenuator is removed.
Too bad henry radio stopped selling their  35 / 50 /100 watt pads, that 
could be bought in  anything from
I think 1-10 db, in 1 db increments.

OM power sells a splitter combiner unit so you can drive 3 of their big 
amps..then combine their outputs.
