This listing is for one amplifier. Onix Dual Mono Power Amplifier A-2150 is a repackaged Proton AA-2120 amplifier. Proton VU Meter amplifiers are becoming more rare, and the AA-2120 is much more difficult to come by compared to the more common D1200 or the smaller AA-1150 at 50 watts per channel. Even that smaller amp has a reputation for being powerful, so you can imagine how much more powerful these larger amp are. Proton AA-2120 power amps were manufactured from 1993 for a few years and had a power rating of 120 watts per channel into 8 ohms. These are true dual mono amps that only share the power button, chassis and the power cord, so they are heavy for their size at 36lbs. Even more rare is the repackaged Onix A-2150. Other than the logos, they appear to be identical inside and out to the Proton AA-2120. They were manufactured in the late 1990s and had a bump to the power rating to 150 watts per channel. These amps are indeed very powerful and can easily shake your room. But they also sound very clear, especially in the midrange. As you can see in one of the photos and the video, Ive paired the Onix A-2150 with a pair of small bookshelf speakers (NHT Super Zeros). Ive been using it as my main amp for everyday use for watching Youtube or Netflix, because it just sounds so clear and concentrated. As for the condition, it works fine without any issues. Both VU meters work well. Appearance is very clean and well cared for. I replaced the feet to aftermarket metal ones as the rubber parts on original ones were disintegrating. I can include those if youd like. As you can see in the photo, I have two of these. I have in the past used them to bi-amp my floorstanding 3-way speakers. These are great looking amps to start with, but with two of them stacked, they really look beautiful. But honestly, these two combined are too powerful for me and my room. So, Im selling one. Of the two, the one Im selling is the one on top with the more green lamps (original bulbs). The other one had the bulbs burn out so I replaced the bulbs with LEDs and its much brighter. You may want to consider LED replacements in the future.

This listing is for one amplifier. Its the 2nd of the two of these amps I had. The other one was sold. This one had the LED lamp replacement. Otherwise, it was identical to the other one, having been manufactured on the same day. In the video, its the one on top, with the brighter more blue VU meters.

I can include those if youd like. I have in the past used them to bi-amp my floorstanding 3-way speakers. But I really didnt need two of these for any of my speakers, but they just looked so beautiful and impressive together. Anyway, I hope you would consider this beautiful and super rare amp.

It has 120/240 volt primaries at 290 watts. It is 6 x  4 1/2 x 4. It weighs 14 pounds. This is a factory-original transformer which can be used to replace a defective unit in any 502 or 502A oscilloscope. It can also be used for hi-fi audio or ham radio applications. Tektronix power transformers were built in-house and guaranteed for the life of the instrument. It has primary/secondary shielding. This transformer has five 6.3 and one 5 volt volt heater windings. Two of the 6.3 volt windings are HV insulated for crt filaments. It supplies the following RMS plate voltages:  19 CT, 350 CT, 440 CT, and 800 CT.  These may be connected in series for various plate voltages. There are two primary windings which may be connected is parallel for 100-150 volt line operation. They may be connected in series for 200-250 volt line ranges. NEW 2/24/08 - From Jur van Slingerland:   I have some information about the Tektronix transformer 120-117 mentioned on your site.  Its not complete but I think it can be useful to others.  I connected the transformer and did some measuring:   pins 5-5                 6.7V pins 7-8-9             355V CT pins 10-11-21       10V CT pins 12-13            5.6V CT pins 14-15-16       446V CT pins 29-17-30       800V CT pins 18-19            6.7V pins 22-23            6.7V pins 34-35            6.7V pins 27-28            6.7V   Pins 1, 2, 3, &4 and pins A, B, C, D are used for primary voltages.  Pin 20 is a mystery to me (maybe a electrostatic shield?)   It looks like there are four 6.3V windings an two 5V heater windings (there are 2 GZ34s in a 502/502A) instead of just one. Tektronix Part number 120-120 This is a factory original power transformer for the 545A oscilloscope. It has 120/240 volt primaries at 1 KVA 500 watts. It is 6 x 5 x 4 1/2. It weighs 18 pounds. This is a factory-original transformer which can be used to replace a defective unit in any 545A oscilloscope. It can also be used for hi-fi audio or ham radio applications. Tektronix power transformers were built in-house and guaranteed for the life of the instrument. It has primary/secondary shielding. This transformer has six 6.3 volt heater windings. One of the 6.3 volt windings is HV insulated for crt filaments. It supplies the following RMS plate voltages: 204, 141, 115, 117 and 186.  These may be connected in series for various plate voltages. There are two primary windings which may be connected is parallel for 100-150 volt line operation. They may be connected in series for 200-250 volt line ranges. Tektronix Part number  120-0431-00 This is a factory original fully EMI shielded power transformer for the 556 oscilloscope. It has 120/240 volt primaries at 1 KVA 840 watts. It is 7 1/2 x 4 5/8 x 4 7/8. It weighs 25 pounds. This is a factory-original transformer which can be used to replace a defective unit in any 556 oscilloscope. It can also be used for hi-fi audio applications. Tektronix power transformers were built in-house and guaranteed for the life of the instrument. It has external magnetic and EMI shielding as well as primary/secondary shielding. All factory leads are intact with connectors. This transformer has five 6.3 volt heater windings. Two of the 6.3 volt windings are HV insulated for crt filaments. It supplies the following RMS plate voltages: 116, 126, 130, and 145.  These may be connected in series for various plate voltages. There are two primary windings which may be connected is parallel for 100-150 volt line operation. They may be connected in series for 200-250 volt line ranges.

It has 120/240 volt primaries at 290 watts. It is 6 x  4 1/2 x 4. It weighs 14 pounds. This is a factory-original transformer which can be used to replace a defective unit in any 502 or 502A oscilloscope. It can also be used for hi-fi audio or ham radio applications. Tektronix power transformers were built in-house and guaranteed for the life of the instrument. It has primary/secondary shielding. This transformer has five 6.3 and one 5 volt volt heater windings. Two of the 6.3 volt windings are HV insulated for crt filaments. It supplies the following RMS plate voltages:  19 CT, 350 CT, 440 CT, and 800 CT.  These may be connected in series for various plate voltages. There are two primary windings which may be connected is parallel for 100-150 volt line operation. They may be connected in series for 200-250 volt line ranges. NEW 2/24/08 - From Jur van Slingerland:   I have some information about the Tektronix transformer 120-117 mentioned on your site.  Its not complete but I think it can be useful to others.  I connected the transformer and did some measuring:   pins 5-5                 6.7V pins 7-8-9             355V CT pins 10-11-21       10V CT pins 12-13            5.6V CT pins 14-15-16       446V CT pins 29-17-30       800V CT pins 18-19            6.7V pins 22-23            6.7V pins 34-35            6.7V pins 27-28            6.7V   Pins 1, 2, 3, &4 and pins A, B, C, D are used for primary voltages.  Pin 20 is a mystery to me (maybe a electrostatic shield?)   It looks like there are four 6.3V windings an two 5V heater windings (there are 2 GZ34s in a 502/502A) instead of just one. Tektronix Part number 120-120 This is a factory original power transformer for the 545A oscilloscope. It has 120/240 volt primaries at 1 KVA 500 watts. It is 6 x 5 x 4 1/2. It weighs 18 pounds.
