Kt66 datasheet pdf
The amp is 95% finished (controls, and connectors not mounted yet), but quite listenable. The only light in the room is the computer monitor with the blue Windows background.
That’s easy: just take the screen-to-cathode voltage and divide this by the triode mu of the valve, i.e. This will be enough to bias the valve almost to cut-off, and we don’t really need more than that!
Key a = anode f = filament g = grid - the suffix number indicates which grid h = heater IC = internally connected k = cathode. Regarding tapping points, Mullard’s EL84 and EL34 data sheets quite clearly state that 43% gave minimum distortion and 20% maximum power, although it was suggested  in 1958 that 20% gave minimum distortion for KT66.

If you’re interested with classic circuit and classic components, then you should try this circuit. KT66 can be used in place of 6L6, but please note that KT66 draws more heater current than 6L6. But it is nice to have these codes available if you are not sure what type of tube you have. The overall schema of the power stage, including values of all components, is given in Figure 48.

The Genalex Gold Lion KT66 is a robust and reliable KT66, it is highly recommended for Hi-Fi and guitar amp applications. Here you'll find manufacturers' data sheets and curves for many popular (and some not so popular ) electronic valve types.

The GU48/833A features rugged construction for high power RF transmitter applications. When you intent to get the maximum out of a 300B, and operate this tube at the limits of safe operation, it is a better idea to use the 300B-XLS in such a case. The Real Audiophile does not care about small power when one is using Single Ended Amplifier. 1: RE: 6J5GT vs 6P5GT in my SE KT88 amp (10.73) Posted by passant on 2007-06-08, 13:50:17 (220.127.116.11) Hi Dan , Looking at your KT66 amp circuit I would say , great amp you got there ! A pair of KT150s can allow an amplifier with a power output approaching 300 watts to be built. Therefore, if you make an amp for 6CM5, be sensible, make sure it can also use 6L6GC, KT66, EL34, KT88 or 6550. High power supply voltages, large and leaky inductive components, and high temperatures are among these considerations.
It says the first cap in the power supply is limited in size by the rectifier tube. With a massive plate dissipation of 70 watts, the Tung-Sol KT150 is the most powerful octal beam tetrode ever produced. EL84, 6L6, KT66, EL34, 6550A, 6SN7 types etc which typically command high prices when offered for sale. Fender literally wrote the book on electric basses, laying the foundation for musical innovation and evolution. The distortion curves when pushed (at lower voltages adjusting the bias) are very close to those of a 6550 rather than a KT88. The 2A3 vacuum tube is a power triode capable of outputting 3.5 W in a single-ended Class A configuration. This is an internet resource for those interested in guitar amplifiers, vacuum tubes, and design tools such as SPICE modelling.

It has eight pins arranged around the circumference of a circle with a diameter of about 11/16 of an inch. This means the PSU must have PT with VA rating above 300VA and be able to provide 6.3Vac x 10A for heater filaments and B+ with 300V-0-300V HT winding good for 400Vdc x 300mAdc. Operating system: Windows 95, Windows 98, Windows ME, Windows 2000 or Windows NT4.TDSL Personal Edition is a 32 bit application, and will not work under Windows 3.1 or Windows 3.11 even if Win32S is installed. The sample was very small (20 6L6GC, 10 EL34, 10 KT66, 8 KT88), and therefore it is to be expected that the market will offer specimen with data lying outside of the grey areas. This website is a useful guide to see the sort of stock we sometimes hold, including some photos and data.
The Genalex KT-66 is considered by many to be the finest of all KT-66s made today.Finding these tubes at a reasonable price is next to impossible, and this is a way to get an excellent value on these wonderful tubes, especially if you need current matched tubes for your amplifier. You can attach your schematic file to the email It is ok to email me a PDF schematic file Please make sure you have followed the file name guide lines above.
I designed a driver PCB using two 6SN7's that can drive just most tubes, triode or pentode. 6550's and KT88's draw a lot more natural plate current than EL34 type tubes draw so quite often the bias will not adjust up high enough in this case. and VT52,6F6,KT66,2A3,6V6G,6BQ5,6L6 as Push Pull Amplifier.and few pre amplifiers.all of Amplifier using off course Tango Transformer. The KT88 fits a standard eight-pin octal socket and has similar pinout and applications as the 6L6 and EL34.Specifically designed for audio amplification, the KT88 has similar ratings to the American 6550 which was designed for use as a servo amplifier. Circuit Construction - Tubes and Biasing I chose the 2A3 directly heated triode power tube to implement the Loftin-White circuit. Then turn on the tester and set the grid voltage on the DMM to the datasheet setting. So the only other available option to M-O Valve Company to wave the flag for England and itself was its proprietary type KT66, which had been around for some years in military applications and had a proven track record. MISCELLANEOUS ELECTRONIC DEVICES trode is why my Jackson 648s tester, and Original Minus Tubes.
Brimar thermionic products KT66 R BTP KT66.
The preferred OEM tube of '50s-era Fender Tweed Champ and Deluxe amplifiers The Tungsol 6V6 has a geometry designed to safely handle the higher voltages used in guitar amps – plus heavier plate and grid materials. When ordering a pair or it`s multiples, the tubes are matched free of charge in configurations: pair, quad, sextet or octet. Txt or determined from the roll chart in the United States, gec +kt66 in about reflex circuits.
Designed as an output tube for battery radios that put out a couple hundred mW of audio, its low Rp makes a really good interstage transformer driver. For measuring the probes are simply installed between the tube socket and the tube, connected to the TAD BiasMaster. KT90: pdf Bold designators are close or identical, Italic designators are different ratings, different pinouts or different filament voltages. Magnetic flux is expelled from the transformers as shown by the red arrows above. A Stereo 17 watt per channel Ultralinear, push-pull Amplifier using 6CM5/EL36 output valves. The purpose of this KT88 / KT66 /6550 / KT90 / KT120 page is to give an overview about what KT66, KT88.
I usually tend to use 5U4GB’s as the rectifier when needing a high current tube rectifier and account for the larger voltage drop with the correct transformer however the 5AR4/GZ34 is a good tube as well. Because of our tradition of supplying the highest quality tubes, we are proud that our ouput is the very best in the world for upgrade and replacement. The W Jan version had a number of final improvements for military applications with a rugged construction which allows the valve to operate in high vibration applications. If a second letter is present it indicates the section of the valve where the element is present in a multi section valve, i.e. KT66 amps, such as Quad 11, are still highly prized in the classic Audiophile market for this reason. You can use the search to find service types or go to the service type lists that you can access from the page More Tube Related Stuff.; Some tube types end with an underscore (_) followed by some letters indicating the Brand or a number if the Brand is unknown. Email me using the email link at the bottom of this page to submit a schematic to the library. I tried a number of different tubes (including the ones recommended on the Tango datasheet) to drive the NC-14, and this was the best I had.
Though 40 Watt is possible, this is a peak value only, and no normal working point. The amp's signal flow in the schematic above is shown by the thick grey line from the input jack at upper left to the speaker at upper right (to see the larger, readable version of a diagram on this page just click on the diagram).
Aside from a 3.71mm difference in lamination thickness and use of flying leads instead of terminals (U-808) these two transformers seem to be technical and physical twins. The JJ 6550's don't make as much power or sound as fat and thick as the JJ KT88 but they definitely fill the void between a 6L6 and a KT88 that is second to none. It is one of the largest tubes in its class and can handle significantly higher plate voltages than similar tubes, up to 800 volts. This amp was designed mostly to work with KT88, 6L6, or EL34 tubes in either triode or ultralinear mode.
It also contains a page or so of the factory codes as well.
Ultra-linear mode and push-pull configurations were introduced respectively in Section 2.2.4 and Section 4.1.4.
