Vintage 1950s AMPEX type 6450 DUAL HIGH VOLTAGE SUPPLY Ampex Tube Preamplifiers, removed from old obsolete rack cabinets during interior demolition work of Movies Screening Room in former 1950′s TV Station building on Manhattan’s West Side. Super heavy: 28 Lbs. Condition: used, transformers seems are working. It has Not Been Tested with radio tubes (we don’t have original tubes), quite old, tons of dirt. Removed from some sort of amplification farm cabinets. Original screws and vacuum bulbs had been missing during demolition. Pilot light is not working. No original tubes Included!!
THIS COMES AS PICTURED. I HAVE HAD A FEW OF THESE OVER THE YEARS BUT THIS IS BY FAR IN THE BEST COSMETIC CONDITION AS I HAVE HAD. MOT OF THE TIME THEY ARE RUSTED (FROM SITTING OUT IN A SHED) AND NEED REPAINT. I WOULD NOT TOUCH THIS ONE OTHER THAN A LITTLE POLISHING. IT WILL MOST LIKELY NEED SOME ELECTRICAL WORK. LOOKS LIKE IT STILL HAS THE OLD WAX CAPS THAT WILL PROBABLY POP IF YOU POWER IT ON. IT SHOULD BE A FUN EASY RESTORATION THOUGH. THE POWER CORD WAS BRITTLE AND MAKING A TOTAL MESS SO I DID CUT IT OFF. THE PLUG CONNECTOR HOWEVER IS THERE AND EASY TO REWIRE (THESE ARE ALMOST ALWAYS MISSING). ALL OTHERS TO USE EIS.
This Ampex 6973 Mono Bloc Amplifier is a vintage piece of audio equipment made in the United States. It is a tube amplifier that is perfect for any collector or enthusiast of vintage electronics. The brand is Ampex and the model number is 6973, which makes it a unique item that you won’t find anywhere else. So, if you’re looking for a piece of audio equipment that is not only unique but also has a rich history, this Ampex 6973 Mono Bloc Amplifier is the perfect item for you. One of them has started to have sthe capacitors and resistors replaced the other one is untouched. I had an injury and just won’t be able to finish them. The power cords should be replaced too. They were working when removed. They have no tubes included.
Overall condition is good- no damage, just some dust, rust, and patina. All tubes are include aside from the four 6550. This is the most robust and powerful amplifer ever made by Western Electric / RCA. These were designed as monoblock amps, class AB, made to power Voice of the Theater speakers, and the like. These are extremely hard to find in recent years, their price and value ever climbing! This will be packed with exquisite care, using double-walled boxes and robust foam wedges and blocks. Tubes will be removed and packed separately, everything with ample protection. Please also feel free to message me if you have any questions.
The cable is 138 meters long and has 3 conductors of tinned coper 30.6 mm. It is suitable for use with AC power or as speaker cable or similar audio projects and is designed for use with vintage amplifiers and tube amps. Track Page Views With.
Vintage Hammond H-AO-33-1 tube amplifier. Taken from a working unit, cosmetically in good shape – a few inside components appear corroded but mostly clean (see photos).
Up for sale two is a rare Soviet tube preamps – LOMO UP-25. Here is the rarest Soviet preamps. Based on three Soviet tubes: 1PCS 6G32P [analogue of EF86] and 2PCS 6N3P [ECC85 / 6L12]. Pair of rare tube soviet-made preamps. You need to have strong engineering and soldering skills to be able to use these. Please see images for condition. Reasonable offers are welcome.
For sale is a fully restored Fisher SA-100 tube amplifier in far better working condition (yes, it sounds and measures better) than when it left the factory in the early 1960s. I did this work myself and this is one of the dozens of pieces of audio gear and test equipment I have restored in the last five years. I did not do this level of a restoration with the intent to resell the unit, but I simply have too much gear and this amp sounds too good not to be enjoyed. Restoration was the following (please also see relevant photo). Nearly all resistors and capacitors replaced including wirewounds where appropriate for heat dissipation. The bulk of the resistors were 1% tolerance of better military grade Vishay metal film resistors. These are on another planet compared to the noisy and out of spec carbon comp resistors. The “sound” of the amplifier is largely dependent on the output transformers and the carbon comps were simply holding this amplifier back and of course a limitation to the reliability of this already hot running small stereo amplifier. The tight, low-reaching bass this amplifier is known for is very much present and enhanced. Potentiometers and switches disassmbled and thoroughly cleaned. Chassis gently cleaned and protected with synthetic wax. Original 7189 tubes were weak and were replaced with a quad matched set of new production Tung-sol 7189s. Russian made before the war. Put some NOS tubes in here if you’d like. The 7247s are still the originals. Tube sockets were cleaned and tightened. The work done on this amplifier is cleaner than that one. I’ll note the cosmetic flaws but if you care about these when you consider the level of restoration undertaken here, you’re missing the point. Power transformer has a slight tilt to it. There was a small nick on one of the edges that I gently filed down as it was very sharp. You can see it in the photos. Some small nicks and scratches, but this amp is far cleaner than average. Rubber feet a bit deteriorated, but still serve their purpose. Additional things you should know. This amp runs hot and it was even hotter before restoration. The temperature is not harmful to the components but it is likely going to be warmer than you’re used to. Terms (Please read these). I sell mostly vintage electronics. As such, these items are old and typically out of spec from when they were new. I do my best to test these items and make sure they work before they’re sent out, but I do not guarantee or represent that they will meet the original specifications. I may not even be able to test them, in which case assume that they don’t work. However, there are times where I may miss something. If that happens, I hope that you would agree that the most efficient way to take care of an issue is if you simply message me before opening a case or doing anything else. I need an outlet for these items online, so I have no reason to send you something that doesn’t work unless I’ve noted that it doesn’t. I pack items correctly. I know what it takes to get an item to you safely. You will NOT have to ask for it. I will do my best to get items out within a few days, however there are instances where that is not possible especially around holidays. The policies here are difficult in this regard because these vintage items in particular need to be moved and packed carefully. I do not want to damage anything by rushing. With this all being said, if there is any reason that you don’t feel that you can leave FIVE stars in every category, please reach out to me before leaving any feedback other than positive with all five stars in every category. Please message me to work this o.
