##  Points well   taken.   Yes u need to buy the rasberry pi,  3 x fans, then 
cable  it  all . 
But still,  even if a ham didnt want to   plug in cables, and install  the 3 x 
fans,  Im sure
he could find   somebody  who would undertake the project.  Its  not a real kit 
in the sense
of a heathkit.   No soldering required on  the  B-26 german amp... just the 
myriad of 
interconnecting cabling between  module boards, installing the  raspberry pi  
then installing the pair of  push pull  120mm fans for the PA heatsink, then 
the 80mm  fan
for the LP filters +  auto tuner. 

##  Some enterprising fellow   could possibly start a small  business,  doing 
the above. 
Then check the calibration, idle currents,, final testing etc.   The end user 
would still be
far ahead.   Another  $200.00  to install the misc items,  calibrate, test, 
would not be

I have one of those German B-26 amps. It is very good: quiet and puts out more 
than 1500 W. But it is a kit: you have to do a some work and buy about $100 
worth of components. I like mine, but I don't use it in QSK, as it has a 10 to 
20 mS R/T delay. (There is more involved than just relays.)

But it is good value and is beautifully made (German)!

  <Your comment about saving a few bucks in a $7K amplifier is on target.


  <Victor, 4X6GP

  ## $7K US funds translates into one helluva lot more in any country outside 
the USA. 

  Just checked, its $9800.00 here in Canada....+ tax, 

  + shipping. Thats a lotta money for no qsk,

  no pin diodes, or vac relays..and no schematics. 

  ## That german made B-26, 1.5 kw output SS amp, 

  160-6M, with the pair of BLF-189 XRAs is the better deal, 72% eff,

  runs cool... but still has no real qsk...20 msecs. But at least vac relays 
could be retrofitted into the SS amp. 

  The german amp is $3450.00 US funds, including built in 2 kw auto tuner, and 
your choice of 13 or 16 db,

  both 100 watt CCS rated input attenuator, and also shipping. You could easily 
buy TWO of the B-26s

  for what one PGXL cost.
