Various Power Supplies For Sale:

Pyramid Phase III, PS-25, 25 amp power supply:

This power supply will furnish up to 25 amps. The voltage
is adjustable from the front panel from 4.5 to 15 V DC.
It includes both an ammeter and a voltmeter on the front panel.
The output connections are on the front, making this a really
great bench supply, as well as great for powering a rig.

This unit works fine, and looks very nice. It may be new.
It is still in its original box, with the packing material
and paper work. The box is marked $299.50!

Buy this one for only $100.

Radio Shack 25 Amp, 13 V DC Power Supply:

The Radio Shack 22-510 is a 13.8 V DC switching power supply
rated at 25 amps continuous duty. Note the 100% duty cycle
rating! It should easily power most any modern HF transceiver.
It is small and relatively light weight.

The front has a lighted power switch. The back has the 13 V
DC output, the 120 V AC input cord, and a fan.

This unit works 100%, and looks extremely nice -- close to new.
It includes paper work -- operating manual, parts list, schematic,
and circuit board layout. Only $65.

Astron RS-12 A
Astron rates this supply at 12 amps intermittent, and 9 amps
continuous. It is ideal for 2 meter or dual band rigs.
With paper work for $35.

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, 13 V DC power supply:
This supply is regulated, with switch and pilot bulb on the front,
and binding post output on the rear panel, along with the fuse.
It works fine and looks good. $28

Micronta 22-120 A, 13 V DC power supply:
This supply is rated at 2.5 amps. It is well regulated. It has a
switch and LED light on the front, with a circuit breaker and output
terminals on the back. The case (left & right side & top) is
basically all a heat sink. This one works fine and looks like new.
No scratches. $30

Homebrew Power Supply:
This power supply is in a very nice gray and black enclosure with
binding posts for the output on the front, along with a pilot bulb
and power switch. The back panel has a fuse and the regulator.
It looks to be good for about 1.5 amps at 12 V DC.
It works fine and looks really great. No scratches or defects. $15

Other power supplies:

"Open Frame" Regulated Power supply

This power supply is a real brute. It produces +12 V DC,
+ 5 V DC, and also - 12 V DC. There are separate voltage
adjust pots for each voltage, as well as current limiting
adjustments. Regulation is superb; less than 0.01 V variation
from no load to loaded.

I can not find a manufacturer marked on it, but the info on
the PC board is great. It appears to be 1982 vintage from
the markings on the parts. The transformer is about a 5 inch
cube, and it includes a 43,000 mfd cap, among others.
Very heavy duty!

Only $30. It will just barely fit into a post office large flat
rate priority mail box for shipping.

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
power supply!

This particular unit works 100%, and looks extremely nice. $85

"Wall Wart" Power Supplies:

All of these are "regular" wall warts - not the new switching type
that create all sorts of noise in your receiver. Use one of these,
and you will not need to put up with all of the interference.

There are many uses for the 12 volt variety.
These all have 2.1 mm coaxial connectors with center positive.
12 V DC at 1000 ma $17
12 V DC at 800 ma $15
12 V DC at 625 ma $14
12 V DC at 500 ma $12
12 V DC at 300 ma $10

13.5 V DC at 800 ma $16

12 Volt AC at 1 amp - Note it is AC, not DC. $15

9 Volt DC at 500 ma
This unit was used on a MFJ 422 keyer, but will also power other
items needing 9 V DC. It has a 2.5 mm male plug on it, tip positive.

Icom BC-25 / Santec HT Charger
Same thing, with slightly different tags. Used with Icom IC-2AT,
3AT, 4AT, IC-32, and many other Icoms. Used with Santec HT-1200,
ST-142, ST-144, and other Santecs. This is the same as the
original wall wart that came with these HTs. 2.1 mm coaxial
power plug output, with center +. Still in box, unused. $15

APC Back UPS 400 Uninterruptible Power Supply:

We all know that this is the season when we get a lot of thunderstorms,
plus the possibility of hurricanes and tornadoes. When that happens the
power can be very unreliable, and have many surges and spikes on it.

Because of this, your electronics should have an Uninterruptible Power
Supply, or UPS. The ones made by APC are considered the best.

The APC Back UPS 400 is ideal to place between the power outlet and
your electronics, including your ham equipment. It is rated at 400 VA,
which should be adequate for most applications.

This particular unit works fine and looks really great -- close to new.
It has recently had a new battery. Only $30.

Noise Filter and Surge Suppressor:

This unit is still in its Radio Shack (#61-2327) box, never
used. It has connections for a computer network (LAN, RJ-45
connector), the AC power, and for phone lines (RJ-11 connector),
and provides noise filtering and surge suppression on each.
It even includes $25,000 insurance against surges. Maximum
power rating is 1875 Watts, or 15 amps. Noise filtering is
listed at 40 db.

This unit is new, in its original box, with its original
paper work. $12

I also have many other accessories available such as many
different types of microphones, HTs, VHF and UHF rigs,
antennas, etc. Just too many things to list here.
Please e-mail your requests.

Prices do not include shipping from Florida.
In all cases, pick up near Ocala, FL would be great.
