It includes a speaker as well as the power supply in a very nice cabinet. It was designed to be used with the Eico 753 transceiver, but can be used with most any of the tube type rigs from the 1960's and 70's. The manual says it provides the following voltages: 750 V DC at 300 ma High Voltage 280 V DC at 170 ma Low Voltage -100 V DC at 5 ma for bias 12.6 V AC at 4 amps for filaments This supply comes from a silent key estate; I am sure it has not been used for years. I do not have a rig to test it, but would expect it to work fine, but the filter capacitors likely will need to be replaced, as is the case with any of the units of this vintage. With manual for $120. Regulated 13 Volt DC power supplies: Icom PS-30 DeLuxe Power Supply: The Icom PS-30 power supply delivers 13.8 VDC at 25 amps. This power supply features a 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 low current outputs. This power supply has a snap-out tilt bracket. 9.5 x 5 x 12.5 inches. This one works 100% and looks extremely nice. With paper work for $175. TenTec Switching Power Supply: "Switcher / 25" 25 amp switching power supply: This is a 25 amp switching power supply in a case that matches the early Omni series case, with the metal bezel around it. It is in a case that is the same size as a 243 remote VFO. It has an ammeter on the front, along with Switch, TenTec logo, and output bulb. The front panel basically looks like a 280 power supply with a metal bezel, but says "Switcher/25" on it. It is very quiet, and well shielded, and does not produce any electrical noise that I could find. $140 EVG Model 10-395, 4 amp 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. $30 Micronta 22-120 A 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. It works fine and looks really great. No scratches or defects. $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 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 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. $12 Icom BC-25 / Santec HT Charger Same thing, with slightly different tags. 2.1 mm coaxial power plug output, with center +. 12 V DC at 50 ma. Still in box, unused. $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.
