Power Supplies For Sale:
These are all power supplies that produce in the neighborhood
of 13.8 Volts DC, unless listed otherwise. All are regulated.
Icom PS-30 Deluxe Power Supply:
The Icom PS-30 power supply delivers 13.8 VDC at up to
25 amps. This power supply features a large lighted meter
which can be set to display amperage or voltage. Four
outputs are provided on the rear panel. Output 1 is a
hard wired, high amperage cable with the Icom standard
6 pin Molex plug. Outputs 2, 3 and 4 provide lower current
This switching power supply has a snap-out tilt bracket,
and is 9.5 x 5 x 12.5 inches.
This one works 100% and looks very close to new.
With paper work for $175.
Astron RS-20 A, 20 amp Power Supply:
The Astron RS-20 A is a very common power supply around
most ham shacks. It provides 13 V DC for many ham rigs.
Solid State Electronically Regulated
Fold-Back Current Limiting Protects Power Supply from
...excessive current & continuous shorted output
Crowbar Over Voltage Protection
Excellent Regulation & Low Ripple at low line input voltage.
Heavy Duty Heat Sink
Chassis Mount Fuse
Three Conductor Power Cord
Input Voltage 105-125Vac
Output Voltage 13.8Vdc (internally Adjustable 11-15V)
Ripple Less than 5mV peak-peak (full load & low line)
Continuous Duty 16 Amps; ICS 20 Amps
Size 5" x 9" x 10-1/2"
This particular supply works great. It only varies 0.01 Volts
with a load! Cosmetically it looks great.
With paper work for only $65.
Astron RS-20 M
Same characteristics as the RS-20 A, above, but has added
voltmeter and ammeter. With paper work for $90.
Pyramid Phase III, PS-35 G:
This power supply will furnish up to 35 amps. The voltage
is front panel adjustable from 4.5 to 15 V DC.
It includes a front panel ammeter and a voltmeter, and has many
extra protection features.
It would be ideal for a high current bench supply, as well as
for a rig. $100
Very heavy duty homebrew supply
This power supply is a real brute. It is well regulated, and
has locking trimpots on the front panel for fine adjustment of
voltage (from about 10 to 15 volts), and also to set the voltage
where the over voltage protection kicks in. There is a large
voltmeter and separate ammeter on the front panel, with pilot
lights for AC power, DC power, and one for when the over voltage
As I said this is a brute. It has a very large transformer, and
three HUGE capacitors, among other things. The output pass
transistors are five 2N3771's on a very large heat sink. The
output is fused at 30 amps, but the supply is probably good for
at least 45 amps, if not more.
This unit weighs over 35 pounds, and is about 8 inches wide, 6
inches high, and 16 inches deep.
It works great. Cosmetically, the builder used nice lettering
on the front panel, but the heavy steel case has been reused.
It does not look bad, but it is not 100% professional.
Buy this brute for only $100.
Staco RPS-6, 6 amp regulated power supply
Ideal for 25 watt VHF or dual band rigs. $30
Stinger 6 amp regulated power supply
Similar to RPS-6 above. $30
EVG Model 10-395, 4 amp power supply
Rated at 2.5 amps, it is well regulated.
The case is a heat sink. $30
Homebrew Power Supply
This power supply is in a very nice gray and black
enclosure and is good for about 1.5 amps. $15
Kepco Variable Bench Power Supply:
This is an ideal bench power supply! It is a Kepco Model ABC
40-0.5, which means that it will produce from zero up to 40 V
DC at up to 1/2 amp. Great for the bench.
The voltage is adjustable with a 10 turn pot from close to zero,
up to about 40 volts. There is a fairly large analog meter that
reads the voltage. There is also current limiting built in that
is adjustable from about 100 ma to up to about 700 ma. The same
meter that reads voltage can be switched to read current, or
short circuit current (the point that the current limit is set).
In addition, there are connections on the back to allow remote
sensing and remote programming. This is a quality regulated
This particular unit works 100%, and looks extremely nice.
Prices do not include shipping from Florida.
I also have many other accessories available such as many
different types of microphones, HTs, HF, VHF and UHF rigs, HF
and VHF/UHF antennas, etc.
Just too many to list here. Please e-mail your requests.
