[AMRadio] Power Supplies FS

[Ken, W8EK]

Power Supplies For Sale:

In all cases, these can be shipped, but pick up
near Ocala, FL is much preferred, especially on
the big ones.

.

Astron Power Supplies For Sale:

Astron power supplies are pretty much the standard
for ham use. They provide 13.8 V DC to power most
all of our equipment, and do it well, with good
reliability.

Features:
Excellent Solid State Electronic Regulation
Fold Back Current Limiting
Crowbar Over Voltage Protection
Heavy Duty Heat Sink
Input Voltage 105-125Vac
Output Voltage nominal 13.8Vdc, but adjustable
Ripple under 5mV
Chassis Mount Fuse

I have several available:

VS-50 M - 37 amps continuous, 50 amps ICS
It has both an ammeter and a voltmeter. Current limiting
and output voltage are both adjustable from the front panel.
$200

RS-35 A - 27 amps continuous, 35 amps ICS; $100

RS-20 A - 16 amps continuous, 20 amps ICS; $65

All of these work well and look close to new.
Tested output voltage varies from 0 to 0.02 volts
under load.

.

Say Electronics SPS-20 M Power Supply:

This power supply is very heavy duty--MUCH heavier duty
than Astron power supplies. Parts are larger, but most important
is that Astron uses two 2N3771 pass transistors, while Say
uses four -- twice as many.

Rating is 20 amps continuous--not intermittent. Voltage is
variable from 3 V to 15 V DC. The current limit is set to
25 amps, and over voltage to 17 V DC. It has two meters --
an analog ammeter and a digital voltmeter.

This one works 100%, and looks the same.

Paper work is included for $110.

.

TenTec 961 Power Supply/Speaker:

The TenTec 961 power supply includes a nice built in
speaker.

I think this is the last linear power supply that TenTec
produced. Being linear, it will not produce electrical
switching noise.

Specs say it is good for 20 amps continuous, or 22 amps
for 5 minutes.

Cosmetically, this supply matches the Corsair II, Paragon,
Omni V/VI series, and probably others.

A nice speaker is included. This particular unit works fine
and looks exceptionally good. I can not find a scratch on it.

Paper work is included for $100.

.

TenTec 252 MO Power Supply:

The TenTec 252 MO provides up to 20 amps at 13 V DC to
power most any 100 Watt HF transceiver. An ammeter is
included.

The color is the chocolate brown / blackish / dark grayish
that matches the TenTec Omni A and D series A, B, and C,
the Hercules Amp, Delta 580, and others of this era, but
it can be used on most 100 W rigs.

The 4 pin molex output plug matches many, many TenTec rigs,
but this one has had heavy duty binding posts added, so
that it can be used with any rig.

This one works fine, and looks good.
With paper work for $65.

.

19 Amp Switching Power Supply:

Radio Shack 22-5088 power supply rated at 13.8 V
DC at 19 amps.

It has overload, short circuit, temperature, and
over voltage protection built in.

It is a small lightweight power supply that can be
used on most any VHF or UHF rigs, and most HF
transceivers.

This one is NEW, completely unused, in its original
box for only $75.

.

Medium Current 13 V DC Power Supplies:

All work fine, and look fine.

Pyramid PS-7 regulated supply
7 amp supply,
modified with a large heat sink on the top cover $25

Staco RPS-6, 6 amp regulated power supply
Ideal for 25 watt VHF or dual band rigs. $28

Stinger 6 amp regulated power supply
Similar to RPS-6 above. $28

.

Pace Communications 5803 Power Supply:

The Pace 5803 power supply is designed to be a bench type
power supply. It varies from about zero up to just over 15
Volts DC output, with up to 2.5 amps current capacity. The
front panel has both an analog voltmeter and analog
ammeter, both with a very soft back light. It also has a
control to vary the voltage, plus binding post output
connectors and switch.

Bottom line is that if you need a bench power supply
this one is ideal.

This one works fine, and looks great. I do not see any
scratches.

Only $35..

.

"Wall Wart" Power Supplies/Chargers:

All of these are "regular" wall warts - not the new noisy
switching type. Use one of these, and you will not need to
put up with all of the interference.

TenTec Model 48-15-800
15 V DC at 800 ma $15

There are many uses for the 12 volt DC 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

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

9 V DC at 50 ma $8
9 V DC at 500 ma $12

.

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

.
Prices do not include shipping from Florida. Pick up near
Ocala is preferred, especially on the big ones.

Thanks.

73,
