This is a used but working tube PA amplifier. All the tubes test at least good on an emissions type of tube tester. One of the 7027A output tubes has a broken keyway. The tube works great but requires care in inserting it into the socket properly. All three inputs work: 2 microphone and 1 phono. Newcomb rated this at 75 Watts using 7027A output tubes in push/pull configuration. It was tested using a CD player into the phono input in the back using an RCA connector. It was tested using an electric guitar into the microphone inputs using the 1/4 microphone jack. I also used a y-connector so that the electric guitar can be plugged into both of the microphone inputs at once. It was plugged into a 4×12 speaker cab. There are screw terminals for 2, 4, 8, and 16 ohm speakers. This amp will overdrive when turned way up and it will move some serious air. It can also be used in 25 and 70 volt installations.

1 Single-Ended Vintage 45 Tube Amplifier W/ Tamura Output & Power Transformers. Single-ended custom 45 triode tube stereo class A audio amplifier with Tamura transformers. Clean look & design. This hand-built stereo amplifier features A deluxe Tamura power transformer that offers many AC voltage options. See the last picture in the listing of the power transformer. The heavy-duty Tamura power transformer will run all day and not get hot. It is a commercial broadcast-grade transformer. These are not made today and are from the 1960s. No transformer built today can match this quality. Chassis size is 17″ x 10 X 3″. Bud brand heavy all steel chassis to better support the transformers. ElectroCube audio grade Mylar capacitors. Point to point hand wiring, with no circuit boards that are difficult to repair and often go bad. If other sellers do not show under the chassis it may be because they use overseas circuit boards. Two gain controls — one for left and one for the right hand. These are Alpha professional brand studio audio gain controls. With one for each channel, you can use them as a balance control only better. As you do not need a preamplifier to accomplish this function. Top of the line Tamura brand power transformer — The Tamura power transformer in this amplifier is a 1960 vintage. It has a large heavy copper band shield around the windings to eliminate hum. It is one of the best power transformers ever made. If they were to reproduce a transformer of this quality today, the cost would be no less than 300.00. Many power transformers just meet the minimun amperage requirement so they get very hot. Not with this Tamura transformer it is a commercial-grade unit and can run all day and just get warm. The last picture is of the transformer used in this amplifier. You can see the large copper band and the quality construction. Check out our entire store for more great products and deals!

This is a used Realistic Tube PA Amp/Amplifier. It has 3 inputs: 2 Microphone and 1 phono that have been tested and all work. It includes a Sam’s Photofact Folder/Schematic for a Realistic Model PA30/60 Amplifier. This amplifier uses a 5U4 instead of the 5AR4 (rectifier tube) shown in the schematic, but all the other components are the same. I used this with an electric guitar plugged into both microphone inputs using a “Y” adapter and a Switchcraft 1/4 to screw on connector on the amp. It was connected to a 4×12 guitar speaker cabinet using the output screw terminals (to a 1/4 jack adapter). It was also used with a CD player plugged into the phono input. It works as it should, with plenty of power; The bass and treble controls also work well. It uses 3 – 12AX7′s, 2 6L6′s and a 5U4. All the tubes test good on a Sencore TC154 emissions type tube tester. It is in nice shape and includes all the knobs and cabinet screws but the bottom plate is missing 2 screws. I tested the Monitor jack on the front with stereo headphones and it works also. Please don’t hesitate to ask any questions. Thanks for checking this out!

You can do a Google search on this amplifier to get more information about it. These output transformers are gigantic, heavy, and very impressive. I also understand that a matched pair like this is quite rare. I have also provided pictures of the various wires associated with both transformers and a description of the resistance values across these wires (see the Description below). DESCRIPTION OF THE TRANSFORMERS. Each one weighs approx. 5 pounds and is approx. All dimensions and the above-listed weight are approximate as noted above. Check out the photo of the transformers next to a 12AX7 tube (tube not included) which shows just how huge these transformers are! Both of these transformers have the same numbers/letters on the bottom as shown in the photos. These numbers/letters are: 51-58 and 138026. I was told that the 138 in the 138026 number means that the transformers were made by Stancor. However, I dont know if this is correct or not and I do not know what these numbers mean. Cosmetically, the photos show the transformers from all angles and please feel free to check the photos out in detail. Both of the transformers look good for their age in my view as the photos show. The transformers do have a number of scrapes, nicks, dings, pits, scratches, missing paint, scuffs, etc. On especially on the tops of both transformers which have some scrapes, etc. Also, the wires coming from the transformers have some dirt, residue, nicks, scrapes, spots, etc. On them, with the wires being of different lengths as shown in the photos. However, in my opinion, the transformers do look good for their age and have a very impressive appearance. Each transformer has 7 wires coming out of it. There are two groups of wires coming out of each transformer. The FIRST GROUP of Wires involves: (1) a BLUE WIRE (wire A in the photos); (2) a STRIPED (wire B in the photos); and(3) a RED WIRE (wire C in the photos). The SECOND GROUP of wires involves: (1) a BLACK WIRE (wire D in the photos); (2) a BROWN WIRE (wire E in the photos); (3) a GREEN WIRE (wire F in the photos); and (4) a YELLOW WIRE (wire G in the photos). I measured the resistance across these wires using an ohm-meter and I obtained the following results (see the photos). FIRST GROUP OF WIRES. (1) Resistance across the BLUE WIRE A and the STRIPED WIRE B = 188 ohms. (2) Resistance across the STRIPED WIRE B and the RED WIRE C = 90 ohms; and. (3) Resistance across the RED WIRE C and the BLUE WIRE A = 98 ohms. SECOND GROUP OF WIRES. (1) Resistance across the BLACK WIRE D and the BROWN WIRE E = 0.4 ohms. (2) Resistance across the BLACK WIRE D and the GREEN WIRE F = 0.7 ohms; and. (3) Resistance across the BLACK WIRE D and the YELLOW WIRE G = 0.9 ohms. All of the above-listed resistance values are approximate and rounded to the nearest ohm. Also, I cannot guarantee the accuracy of the above-listed resistance readings. They would make a great addition to any vintage electronic collection. Feel free to check it out! They should therefore not be considered connect and use items. I have not done anything to these transformers and all of their parts, wiring, and components. The above-described transformers may have been worked on by someone else in the past, but I dont know whether this is true or not. No other items are included. However, I do not know how much repair work, parts, components, wiring work/replacement, etc. However, I will do my best to try and prevent these situations when I pack this equipment although I cannot guarantee that they wont happen. It is therefore important and necessary that both of these transformers (along with all of their parts, wiring, and components) be examined thoroughly by an electronic expert inside and out before these transformers are operated, tested, worked on, repaired, connected to any speaker(s), connected to any amplifier(s), connected to any other equipment, modified, disassembled, handled, and/or used. Any repairs to these transformers (and all of their parts, wiring, and components), as well as the connection of the transformers to any speakers(s), amplifier(s), other equipment, etc. And the use of these transformers and all of their parts, wiring, and components should only be attempted by an electronic expert. Furthermore, I cannot guarantee or warrant that your ohm-meter will provide the same resistance values associated with the transformers that my meter provided as outlined above. I have no idea whether everything is original or not in the above-listed transformers and I therefore cannot make any warranties regarding originality. I also do not warrant that these transformers are complete and I do not know if there are any missing parts, components, wiring, etc. The item “RARE VINTAGE PAIR OF LARGE OUTPUT TRANSFORMERS FROM QUAD 7591 TUBE AMP AMPLIFIER” is in sale since Tuesday, October 23, 2018.
