6v6 heater current

Sep 15, 2021. #5. Outside of plate voltage limitations, It's the power tube heater filament requirements that also really limit what can and can't be placed in the amp. 6L6GCS require double the heater filament current compared to 6v6. You'll likely burn up the PT filament winding by overheating it, essentially making the winding look. The fact that people can swap 6V6 and EL84 in guitar amp circuits says nothing; people routinely swap 12AX7, 12AY7, 12AT7 and 12AU7 there too although all they have in common is a pinout and heater current. 6V6 and EL84 are almost bound to have a similar required anode load because they are designed to run similar power from a similar supply. 2. EL33 6V6. The 6V6 and EL33 are NOT equivalent! A hasty note of warning! They have the same base, connections and heater volts but differ considerably. THe heater current of the EL33 is 0.9A compared with 0.45A for the 6V6. More seriously the biasing requirements are different and could cause dangerous excess anode currents. I am considering a pair of Visseaux 6M6G, also stated as equivalent to EL33. However data sheet for the 6M6G specifies heater current of 1.2A and for EL33 0.9A. Our learned colleague @Deyan reassured me the 6M6G will work with the 6V6 --> 6AS7 adapters he built for me to use in Elise / Euforia, but I'm confused by the discrepant data sheets. Voltage is 19V and resulting 40mA kath. current . The data specs of the 6V6 says max. Plate dissipation 12W and with 40mA you will be close to the limit. ... Assume 4mA for the screen left 36 mA Plate current. Title: 6V6GT 5V6GT Author: General Electric Subject: JA-FP-2000-12-26 Created Date: 12/26/2000 8:47:35 PM. EL84/6BQ5 REISSUED.

The 6V6 is an Octal based beam-power tetrode, introduced by Radio Corporation of America RCA United States during 1937. The 6V6 is similar to its larger sibling, the 6L6. The 6V6' strength over the 6L6 was the lower input powere required and the consequent ability to run on lower rated power supplies and consume lower heater current, sure, the. A Comparison of Current Production 6L6GC Tubes. RCA introduced the 6L6 to the world in the 1930s. It had a metal envelope which was popular at that time for use in radio sets since it was less likely to break than a glass envelope. Revisions to the original metal 6L6 such as increased power handling and glass envelopes yielded new designations. Heater Current: 450: Ma: Maximum Heater-Cathode Voltage DC & Peak: 200: Volts: DC, Heater Positive with Respect to cathode: 100: Volts: DIRECT INTERELECTRODE CAPACITIES. Grid to Plate: 0.7 ... The Type 6V6 is a beam power pentode intended for service as a general purpose audio power amplifier or vertical deflection amplifier in television. The big land at the bottom is the DC power. The cuts are primarily to disconnect the DC power from the tube heaters So you see two cuts near the 12AX7 preamp tube socket on the left, and two cuts near the EL84 output tube socket in the middle. The cuts disconnect the two heater pins for each socket. A few holes are drilled also. want, yet you miss bottom line, no 6V6(s) amp will run 6L6(s) tubes the way THEY ARE MADE TO RUN because of the $ point iron that can NOT handle the 6L6 THE WAY IT IS MADE TO RUN. Heaters will drain all current, and the audio will just drift along. Now maybe you may LIKE that sound, but the tube &/or circuit is nothing like the 1st. This is the type most often found in electric guitar amps, and the current desire for the "tube sound" has caused demand for these tubes to skyrocket. Unfortunately, the modern made Russian and Chinese versions of the 6V6 often cannot handle the high plate voltages some of these amps use, and they self destruct in a bright laser light show.

This is a suitable replacement for any 6V6 = 6V6G = 6V6GT = 6V6GTA = 6V6GTY Pentode tube type. We have lightly used pieces in stock at this time which are supplied in white boxes. These must pass our stringent life requirements for new tubes so they are tested screened and matched, but have been placed into equipment at some point in time. $59.99. The 6V6 required less heater power and provided less distortion than the 6F6, while still offering higher output in both single-ended and push-pull configurations. History. ... Current use. Generally 6V6 tubes are sturdy and can be run beyond their published specifications, except for the 6P6S, which has poor tolerance for out-of-spec operation. 12.6V 150mA heater circuits. Current production of 12AU7 takes place in Russia, Slovakia, Serbia and China. 5Y3G The 5Y3 is a medium-power directly-heated rectifier vacuum tube introduced by RCA in 1935. It has found wide use in tube radios and early guitar amplifiers (of the Fender Champ type.). Le Conseil national de la Révolution algérienne ( CNRA) est créé lors du congrès de la Soummam du FLN . Il est l'organe suprême du FLN durant la guerre d'indépendance 1. Le CNRA est seul habilité à prendre des décisions d'orientation politique, militaire, économique et sociale. Le CNRA désigne les membres du Comité de coordination. Filament or heater glow is also something you’ll typically see when viewing a vacuum tube in use. The filament in a tube has the job of heating the tube’s cathode up to a temperature where electrons are excited and start flowing toward the positively charged plate/anode. All common audio tubes will have a heater filament. More complicated this one. Connect the two 6SK7 valve heaters in parallel and then connect them is series with the heaters of the 6V6. Now the total voltage needed to power the heaters is 6.3v + 6.3v which is of course the 12.6v of your battery. HOWEVER the current distribution is not correct and MUST be corrected or the 6V6 will be damaged. 6V6 is a beam tube while 6K6 is a power pentode, so the the 6V6 would have made louder undistorted output but most ordinary folks wouldn't notice the difference. 6F6 draws more heater current (.7A vs .4 for 6K6, .45 for 6V6) so replacing 6K6 or 6V6 with 6F6 would cause a bit of extra load on the power transformer. The three key reasons are output impedance, filament current and plate current. First off, the 6v6s need a higher load than 6L6s for optimum power. You can compare this to the difference between a 4ohm and 8 ohm speaker. ... The 6L6 heater is rated at 6.3 volts, 900 ma, two times the existing draw of the 6V6. So in amps like Fender Princeton. the original push-pull PX-4, producing 4W (or 8W with higher supply voltage) push-pull PX-25, producing 12W. push-pull 6V6G triodes, producing 2W. All of the designs recommend MH4 valves in the phase splitter and driver stages, but list the 6C5 as an alternative. The 6C5 is a forefather of the modern 6SN7. The 6V6 is an Octal based beam-power tetrode, introduced by Radio Corporation of America RCA United States during 1937. The 6V6 is similar to its larger sibling, the 6L6. The 6V6' strength over the 6L6 was the lower input powere required and the consequent ability to run on lower rated power supplies and consume lower heater current, sure, the. One of the 5v heater lines is connected to the 6V6 heater pin 2 and the second 5v heater line is connected to the 6V6 cathode. I can't see how any heater current would flow unless the cathode and heater filaments were shorted together. Apr 18, 2021 #18 Lowerleftcoast Poster Extraordinaire. Joined Dec 30, 2019 Posts 5,213.

Huo-Long Heater: Allowed Allowed Allowed Allowed Secondary Shotgun: Always Sandvich: Allowed Allowed Allowed Allowed. There has been many 6L6 variations, but the most common ones today are: 6L6GC - 30W version. Can be used anywhere. 6L6GB / 5881 - 25W version. Can only be used on amps that call for 5881. KT66 - A 30W variation of 6L6, requires higher heater current. You can use 6L6GC where any of the other tubes are used, so if you aren't sure, go with 6L6GC. 6V6 is a beam tube while 6K6 is a power pentode, so the the 6V6 would have made louder undistorted output but most ordinary folks wouldn't notice the difference. 6F6 draws more heater current (.7A vs .4 for 6K6, .45 for 6V6) so replacing 6K6 or 6V6 with 6F6 would cause a bit of extra load on the power transformer.

Heater impedances are much lower, normal current much higher, than plate currents. The high-volt winding will probably melt before the 6V6 heater pops. IAC, if you have shorts across power-tube pins, "something" is probably gonna blow, and the possible combinations are too many to predict/prevent. Wire cleanly, use good tubes, and keep your. A pair of 6V6GTs are good for around 10-20W depending on the topology of the output stage. They have a heater current of 0.6A compared to the 6L6 family of 0.9A. Just like its 6L6 brother it is available as the 6V6 a metal tube, 6V6G a glass "coke bottle" shape and the 6V6GT a tubular glass envelope.

The 6V6' strength over the 6L6 was the lower input powere required and the consequent ability to run on lower rated power supplies and consume lower heater current, sure, the. From a current perspective, I'd appreciate thoughts as to whether it'll be ok. ie: 2 x 12AX7 + 2x KT88 + valve recto v's 4 x 12AX7 + 2 x 6V6. 2. Unused Triode in the schemo ... It may sound a bit complex, but you could power the 12AX7 cathode follower triode from a separate 6Vdc heater supply generated from the spare 5VAC winding - and connect.

Calgary, AB T2E 6V6. 403-250-7430 [email protected] The '12AX7′ Tube. The 12AX7 is a miniature high-mu twin triode. This tube is especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators and numerous industrial control circuits where high voltage gain is desired. A centre tapped heater permits operation of the tube from a 6.3V or a 12.6V heater supply. Preamp. 6 Volt - Medium & Large. 6SN7 - 5692 - 6F8G - 6H8C. 6SN7 - 5692 - 6F8G - 6H8C. One of the most famous preamp tubes of all time. The 6SN7 and it's equivalents were once the most popular tube. These are octal based tubes and were released early on, far before the small 9 pin preamp tubes we are familiar with today. Big tight bass, smooth mids and tops but still cut through the mix well. Lower heater current than the 34's and the amp hardly got warm. The 6V6 has a very similar sound but the 6L6GC has a bigger and tighter bottom and overall just oozes rock tones. This is the valves going forward for me. Efficiency is the main reason 6V6 was used so much - less heater power, less screen current, so it replaced most of the earlier tubes used at the 3-15W output level. It meant that manufacturers could use a smaller transformer for lowest overall cost, and less heat is always good. Consider that 6L6 draw twice the heater current of 6V6. And that for similar screen grid voltage, anode voltage and anode current, the magnitude of the bias voltage will need to be increased.
