I will never sell a tube that is below standard…… I have sold many tubes here on Ebay, and all my customers have been completely satisfied. I will work with you in good faith if there are any problems, or if you are unsatisfied in any way. I want your business now and in the future, so I assume you are the boss, and I am the employee. All tubes are tested for shorts, continuity, and emissions. I prefer PayPal. ALL CUSTOMERS PLEASE READ ALL NOTES BEFORE BUYING FROM ME !! 1.  RETURNS: It is my highest desire that you are completely satisfied with your purchase from me. I will bend over backwards to make sure that you are a happy customer. If anything you buy from me is less than satisfactory, message me BEFORE you either open a case or hit the “item not as described” button. Sound quality is tremendously SUBJECTIVE. For tubes returned for noise or sound quality of any kind you pay for the shipping we refund the purchase. We refund the price of the item NOT THE SHIPPING COST. If we sent the wrong tube we will of course pay for return shipping. For any tubes that are DOA we require that you send a us a picture of the shipping box to show us the damage. We test EVERY tube sent out and none should be DOA unless broken in shipping. 2.    PLEASE NOTE:  Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily. If you wipe off the silkscreen while handling the tube you diminish their value by up to 70%. DO NOT handle the tubes or hold them from the cylinder. ALWAYS hold them from the ENDS. If you are returning tubes and they are not in the same condition cosmetically I cannot give you a full refund. THIS IS VERY IMPORTANT. 3.  UNLESS YOU MAKE ARRANGEMENTS WITH US BEFORE YOU PURCHASE, YOU MUST PAY FOR ITEMS PURCHASED WITHIN 2 DAYS OR A CASE WILL BE OPENED FOR AN UNPAID ITEM!!! 4. TESTING: I test all tubes that I sell in one way or another, or I will state untested. I have a B&K 747 tube tester. This is a mutual conductance tester. It give a percentage value of gm for the tube under test and checks for shorts and grid emissions. I also use a Tektronix curve tracer for testing triodes. I give a number of evaluations for tubes. One evaluation is a screen shot of the tube with a high voltage applied to the plate. This helps the buyer see the linearity of the tube in question at the highest voltage the tube will see in a real circuit. The Curve tracer steps the triode through 10 gate/grid voltages starting with -10 volts and going to 0 volts. The lines show how the tube conducts throughout that range. At 0 volt the tube is at max conduction and is the top line on the display. It is easy at that point to take where that top line intersects the plate voltage, find the milliamp level and compare it to the datasheet. I give those numbers for you in the Item condition box. To further help the buyer I also include the Design values, for gm and ma readings in the table. This can then be compared to other tube sellers using inferior test methods such as Hickok,  Amplitrex, and other testers. The Tektronix curve tracer gives values within 3% of the actual value. The very best portable testers only can approach 10% accuracy.5.    Please note: The numbers given for gm are what I see on my tester. I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I dont guarantee or imply anything else. 6. VERY IMPORTANT!!! Vintage tube testers almost always, due to age, have VERY LOW HEATER VOLTAGES!!!  Every tester I have ever bought is below 6 volts when selecting 6.3 volts. They average 5.8 volts. The voltage NEEDS to be 6.3 and 12.6. You can calibrate a vintage tube tester all you want. If the heater voltage is not right, you will NEVER get the right gm value. I have customers complain that their tubes are not the same as what I see on my tester. They say they have a calibrated tube tester. I have 40 tube testers. On all of them I have an outside regulated DC power supply that feeds the tube tester the correct heater voltage. 7. I dont check each and every tube for noise or tone. This is SUBJECTIVE and it is too time consuming. If you dont like the noise level or the tone we offer a hassle free refund policy.  International customers note: 1. Please wait for us to invoice you for the correct amount. If you have purchased more than one item, we must calculate how much the shipping will be. Shipping will be HIGHER due to insurance and shipping methods needed for expensive item totals. If you are buying only one item this will not be an issue. 2. Under no circumstances will we state on a US customs a declared value of less than the sale price. This is an honesty issue. We are honest with everyone to the best of our ability to do so. We want you to trust that what we say is true. There cannot be that trust, if we make false statements knowingly to anyone. If your country has tariffs/taxes so high that they cause large numbers of normally honest folks to make false statements, we urge you to work for change of those laws. 3 International buyers if you bought more than one item and want combined shipping it will ship in 2 days. 4. And all the Angels sang because the heavenly music was playing and it was turned all the way up.   Listing and template services provided by inkFrog

1x RB-5 soviet Krypton filled arrester gas discharge spark gap tube USSR NOS OTKLot of 1 pcs.New, never used, from old stockDischarger RB - spark gap is designed to protect communication lines, antenna devices, circuits and devices from lightning discharges and other types of short-term overvoltage. Arresters RB belong to ionic devices using a spark discharge. The spark gap container is filled with an inert gas (usually krypton). When normal voltages not exceeding the rated voltages operate in the protected circuit, the quiet discharge mode is set in the arrester. The resistance of the arrester under these conditions is so high that its inclusion in the line or circuit practically does not affect their operation. When the voltage exceeds the permissible, a spark discharge is formed in the RB arrester, its resistance drops sharply, the arrester, as it were, short-circuits the line, protecting the equipment connected to this line from overloads. In this case, a large current flows through the spark gap, and the voltage across its electrodes decreases. If the power of the overvoltage source is high, then the spark discharge turns into an arc discharge, if this power is low, then with a decrease in the discharge current, the device will switch to the quiet discharge mode, since at the gas pressure existing in it, there is neither spark nor glow discharges at normal voltage on the electrodes are not saved. Specifications: Breakdown frequency, Hz: no more than 1 Hz Breakdown energy, Joule: no more than 10 Breakdown voltage between electrodes (line-line), V: not less than 500V Breakdown voltage between electrodes (ground-line), V: not less than 340V, not more than 460V Electric discharge termination voltage, V: not less than 210V Insulation resistance by electrodes, MOhm: not less than 200VDiameter, mm, no more than 18 Height, mm, no more than 60 Weight, g, no more than 12 Pin assignment: 1 - Line 2 - Line3 - GND Combine shipping is accepted.If you need less or more items of this type, or if you need add some other items, contact us, and we will make special listing for you.Give us the list of items you need, and well do the rest. We have many other vacuum tubes for audio and other, ask us if you need any of them. Items are shipped from EU- Lithuania Post via expedited International tracking.

The very best portable testers only can approach 10% accuracy.5.    Please note: The numbers given for gm are what I see on my tester. I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I dont guarantee or imply anything else. 6. VERY IMPORTANT!!! Vintage tube testers almost always, due to age, have VERY LOW HEATER VOLTAGES!!!  Every tester I have ever bought is below 6 volts when selecting 6.3 volts. They average 5.8 volts. The voltage NEEDS to be 6.3 and 12.6. You can calibrate a vintage tube tester all you want. If the heater voltage is not right, you will NEVER get the right gm value. I have customers complain that their tubes are not the same as what I see on my tester. They say they have a calibrated tube tester. I have 40 tube testers. On all of them I have an outside regulated DC power supply that feeds the tube tester the correct heater voltage. 7. I dont check each and every tube for noise or tone. This is SUBJECTIVE and it is too time consuming. If you dont like the noise level or the tone we offer a hassle free refund policy.  International customers note: 1. Please wait for us to invoice you for the correct amount. If you have purchased more than one item, we must calculate how much the shipping will be. Shipping will be HIGHER due to insurance and shipping methods needed for expensive item totals. If you are buying only one item this will not be an issue. 2. Under no circumstances will we state on a US customs a declared value of less than the sale price. This is an honesty issue. We are honest with everyone to the best of our ability to do so. We want you to trust that what we say is true. There cannot be that trust, if we make false statements knowingly to anyone. If your country has tariffs/taxes so high that they cause large numbers of normally honest folks to make false statements, we urge you to work for change of those laws. 3 International buyers if you bought more than one item and want combined shipping it will ship in 2 days. 4. And all the Angels sang because the heavenly music was playing and it was turned all the way up.   Listing and template services provided by inkFrog

WOW Very rare Giant Lot of TG-57 Spark Gap Tubes Made By Bendix . You get the entire Lot for the Price . Best Offer get them All

This is for one Western Electric or Westinghouse spark gap tube. It contains Radium and puts out over 600 counts per minute as measured on a Radalert 50 digital meter. I measured one recently and it was putting out way more than 600 CPM. A pancake type Geiger counter would probably read much higher. These can be used as a check source for your GM meter. The tube may show some signs of used with some darkening of the glass, but they still put out the counts and will be shipped in a container inside of another box. Some of them may have dirt on the glass due to storage. I will try to get as much of it off without erasing any numbers. They have a much higher count than the Signalite TG series that I used to sell. Also Radium has a much longer half life than Cesium 137. Radioactive. Radiation. Some international customers have had problems ordering with US Ebay. Try UK Ebay to see if it will go through on that site.The Original ONE HOT MOTHER. Accept no substitute.
