This came in from a ham radio estate, have no clue what this does or is for. Use zoom, I did not plug in, I would think you want to bring this up on a variac… Not sure if amp or power supply or? So untested, as found, no bottom panel. Please see all pictures and use zoom feature. Often the pictures describe the item better than words. Also please see the 11,000+ vintage radio related parts and other great antiques and oddities I listed. Old Radio’s are Fun and getting harder to find! Just like radio parts? Thank you for you order and please follow my store. ! New items added daily. Also you can go into my store and pick the category for easy shopping. Best to you and Many Thanks, Mike.

Welcome to our listing and thanks for visiting. After viewing this item, please check our other listings. Here are three type 2A3 radio or electronics tubes. Please view the photographs as we are not experts in tubes. There are three tubes; each one is a type 2A3. One is inside a box. The box and the tube are marked “Sylvania”. The tube is marked “2A3″ on the glass. Each of the other two tubes are marked “RCA”, and marked “2A3″ on the glass. These two tubes do not have boxes. We used a Hickok model 1575 tube tester and we tested the tubes. The Sylvania tube and one of the Rca tubes tested very good. The other Rca tube tested good. Even though the Sylvania tube is in its original box, we are not certain it is an unused tube. We hope that the photos will help those who are interested. We will do our best to answer any questions. Have a nice day. We hope that we have described our items to complete satisfaction. We are not on-line everyday though, so please be patient for the reply. This is to cover costs of boxes and packing material. We do not make any profit from this.

Being an electronics tech, I see voltages that are way too high for the designed circuit. Nice looking bucking transformer with stainless cover! Turns device and your equipment on or off. You have a choice of 3% or 7% voltage drop. All vintage tube equipment should be using this voltage reducer. Read on; After WWll and up until 1968, household voltages were 117 volts. Typically voltages these days range from 120-125. Your vintage audio equipment was designed to operate around lower voltages of years ago. You might ask yourself what is a few extra volts? Take into account that the power supply in your vintage device is multiplying those few extra volts many times so that the end result could be 20-30-40 volts more than the circuit was designed for. This could lead to transformer failure, component failure and shorter tube life. As you can see in the photo, the voltage reducer brought the line voltage down from 124 to 116. This is approximately a 7% drop. Simply plug your vintage electronics into the reducer outlet. Will work with equipment drawing up to a total of 4 amps. Has protective 4 amp fusing. Metal box is grounded through heavy duty 3 wire power cord. As an example; Photo shows voltage of Dynaco ST-70 at 467v on todays line voltage and then 438v plugged into the voltage reducer. The correct voltage for this Dynaco amp calls for 435v at this point. Also your filament voltage will be more in line with what it should be. All other voltages are much closer to Dynaco factory specifications with the reducer. Your device will run cooler and safer, extending component, transformer and tube life! Please state voltage drop preference when ordering. Strongly recommended for Dynaco St 70, since they were produced with power transformers designed to operate with 117 line voltage. Your transformer will run cooler, tubes will last longer and all voltages will be closer to where they should be!

The product is a lot of 130 vintage vacuum tubes from brands like GE, Sylvania, and RCA. These tubes are intended for use in radios and amplifiers, and they were manufactured in the USA. This wholesale lot of tubes offers a collection of NOS (new old stock) items, ideal for vintage electronics enthusiasts or collectors looking to restore or build equipment from a bygone era. Original boxes, RCA Sylvania, General Electric radio amp, vacuum tubes, wonderful vintage metal carrying case.

Scott Amplifier / Power Supply Chassis. Here is a description that I found on the internet that appears to match this item. It may be a late Philharmonic (or Phantom Deluxe) Amp/Power Supply Chassis. It is uncommon in respect to the finish on the power transformer and the plug layout for the speaker connections. I have been told that chrome was in high demand immediately preceding WWII and in the later production years, the PTs were black in some models. If you look at the contours of the power transformer, you will see that it matches the more typical chrome counterparts. The interconnect sockets are rectangular instead of round and accept Jones plugs. This chassis is very similar to a Laureate but with the layout and tube compliment of a Philharmonic(or Phantom Deluxe). This chassis is set up for 5U4G rectifiers and a quad of 6L6G output tubes. Tubes are included what you see is what you get. This particular amplifier appears to have been restored in recent years as it has a new power cord, new electrolytic caps on the bottom of the chassis with the (top) originals left in place (one has a broken phenolic mounting wafer) and a few new capacitors. The underside of the chassis is clean and the wiring looks very nice. The top of the chassis is poor to fair in my opinion, there is moderate pitting on the Chrome chassis, the filter chokes and the cover of the driver transformer look pretty good, please look at the pictures and judge for yourself. The person who we got the amplifier from left the radio chassis and case behind and when he went back for these items per my request, they were long gone. The tubes appear to be as follows. 2 each 5U4GB rectifiers and 4 each 6L6G (or equivalent) output tubes. I suspect this item is probably functional but I have no way to test it. I will package this item carefully in a sturdy box to insure that it arrives in the same physical condition as seen in the pictures. I will remove the 6 tubes and package them in another box and box them with the amplifier. This amplifier / power supply assembly is a fine example of American made high quality radio equipment and was hand built with the state of the art technology of its time and the finest American made parts that were available. The pictures form part of the description.
