W7RY Ameritron AL-82 AL-1200 AL-1500 SB-1000 AL-80 QSK Board Linear Amplifier

Description

W7RY Ameritron QSK Board
This board will
work in MOST ampli
fiers
such as
Amp Su
pply, Henry, Swan and others. A 24 vo
lt 300mA AC
transformer
is all that is needed
to supply all voltages to this board.
If your looking for a QUIET and FAST replacement relay system for the
noisy relays in your linear amplifier, look no
further.
This auction is for a HIGH QUALITY PC
board only
as shown.
The board also provides
"soft key"
as part of it's design. Your transceiver will only see 10 volts DC @ 1ma to key the amplifier. You can also key the amplifier with + voltage. (5-20 VDC @ < 10 uA)
You will need to purchase a input relay board that is available from me here:

You can use whatever relay you want, but my relay works very well, is easy to mount, and is super fast!
You will also need a 26.5 volt vacuum relay such as a Jennings RJ1, Kilovac  HC-1, Siemens V311 or a  VHC-1.
These relays are available from Henry Radio or RF Parts. These relays are the only ones fast enough. Do NOT use anything other than these or its
equivalent
.
One side note...
I have observed that in ALL of the amplifiers (SB-220, SB-200, TL-922, AL-82, Drake L4B) that I have installed FAST W7RY QSK RELAY systems into, have QUIT arcing in the the tuning capacitors even with no additional parasitic suppression methods! In my opinion, the reason for 99.5% of tuning capacitor arcing is improper T/R relay sequencing and SLOW open frame relays that cant keep up with your modern transceiver.
Parts list and instructions are sent via email
after
your purchase when you email me which is shown above. My "callbook" address works well too.
This auction is for a HIGH-QUALITY PC
board only
