TUBE The late seventies KT77 amps that I am still abusing all use a 1k5 on each G2. 460V on G2 and the Plate is at about 465V. 3k6 OT for two output tubes and 1k8 OT for the quads. The very late versions actually added a 1k between the B+ node and the screen resistors. Whether adding to an existing audio or video system or as part of an all new system, you are certain to notice the clarity, detail and depth of performance which make Proton products among the best in the world, regardless of price.

My Sovtek 5881 WXT | 6l6 WGC Tube Guide has been immensely popular, and I thank everyone for the many emails I receive . d as well as the countless links that have been posted to it all over the web. The transmitting tubes TT21 and TT22 have almost identical transfer characteristics to KT88 but a different pinout, and by virtue of their anode being connected to the top cap have a higher plate voltage rating (1.25 kilovolt) and a higher power output capability of 200 watts in class AB1 push–pull. 🐇🐇🐇 This is a list of vacuum tubes or thermionic valves. Before the advent of semiconductor devices, hundreds of tube types were used in consumer and industrial electronics; today only a few types are still used in specialized applications. The curves agreed very closely with the RCA data sheet for the 6AU6A, confirming that the tracer works and the tube is still functional. That tube has to be at least fifty years old. That it still works was a big surprise as it has travelled everywhere in my electronics junk box over the years through several homes I have owned, and has not received the best treatment.

EL34/6CA7-EH/SOVTEK EL34/E34L/STR HARMA: The Harma is a specially tested/selected valve which is of European manufacture and takes its roots from the M.O.V KT77. The valve has the widest frequency response and the highest plate dissipation, 30 watts, out of all the valves tested. The JJ KT77 have crystal clear 3-D cleans, extended lows and highs. This KT77 has very thick articulate breakup. For the most part, the JJ KT77's will bias up same as an EL34/6CA7. As always, please check with your amp tech before swapping different tube types. Specifications. JJ KT77 Data Sheet. BRIEF DATA KT77 BEAM TETRODE A beam tetrode with an absolute maximum anode dissipation rating of 32 watts. The KT77 is designed for use in the output stage of an af ampli- fier. Two valves in Class ABI give a continuous output of over 70 W. The KT77 is also suitable for use as a series valve in a stabilised povær supply. HEATER Heater voltage

The most accurate method to test tubes, the curve plots can actually be compared to the printed examples for each tube type that appear in the manufacturer technical data sheets and books. This matching is provided at no extra charge for any EL34/6CA7 type of power tubes! Note: It is sceptical to read these factory datasheets for Russian tubes. These tubes is designed in USSR without any market and a competition. Product absolutely did not require any advertisment. And manufacturers indicate double smaller limits of time of service, warranty output Power, anode voltage, etc. In common with all 'E' prefix tubes, using the Mullard–Philips tube designation, the EL34 has a heater voltage of 6.3 V. According to the data sheets found in old vacuum tube reference manuals, a pair of EL34s with 800 V plate voltage can produce 90 watts output in class AB1 in push–pull configuration. However, this configuration is rarely found.

help Test small objects to find out if they are a potential choking hazard for infants or toddlers; If a toy is small enough to fit through the opening in the choke tube tester, it could pose a choking hazard for children under the age of 3; Set of 3 choke tubes. heart List of Preloaded Tubes The test setup data for each tube, including the voltage settings and the expected emission current and transconductance, is stored in an on-board EEPROM device. This memory device retains its memory with power off, so tubes can be tested without connecting the unit to a computer. Have now tested and run all 8 of my 70s era 6CA7 made in the USA big bottle tubes. They have various names on them: GE, Sylvania, Gold Lion, and RCA. But all appear to be the same tubes. They all test as new on my Sencor emissions tester, and range from 49 to 51 on my Sylvania conductance tester. Tight matches. Since the El34 is a true pentode and the KT77 is a beam power tetrode, the EL34 will have more screen current than the KT77. You should be just fine running 470 ohm screen resistors with the KT77's. I wouldn't change the OT tap either.

Jun 07, 2014 · Granted, I change tubes every 12-14 months, but that's just because I find they lose some mojo after being used for that long. Not just JJ's, but any tube.

The Svetlana 6L6 Medium tubes have the classic Sylvania STR sound.Soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal. Soft-rated tubes break up easier and have the least headroom, yielding a heavier, harder distortion. Also, your numbers don't match the data sheets I have (or those on the DuncanAmps site). The Amperex EL34 sheet shows 11.5/22.5 mA per tube (zero-signal/full power), while the GEC KT66 sheet shows 2.5/9 mA - at a higher-voltage operating point. These numbers suggest that EL34s draw between two and three times the screen current of KT66. It really is still a tube tester that is fast, and easy to use. Should you own a B&K 707, do ‘look after it’, and make sure you have the owner’s manual. All in all, I really do like B&K tube testers, as well as B&K tube tester advertising. With preamp tubes, such differences can cause different volume settings (for example) to achieve a given sound level, but using a different control position, has now likely changed the response of the circuit, and therefore, the character is the sound. The tube did cause the change, but only indirectly in this example.
