A quartet of 6L6s seems to be a good choice for a 50 watt (per channel) amplifier. The design of a two channel amplifier required separate power transformers for each channel. The reason is that Hammond doesn't make anything big enough to power two 50 watt channels. ue to popular demand I include here three push-pull class AB amplifiers using EL84 output valves. The first circuit in the PDF shows an archetypal, small to medium power push-pull amplifier configuration that uses a triode-pentode (ECF83) in the front-end.
Nov 13, 2012 · I spent a year on this project with different output tubes, output iron, coupling caps, feedback and B+ levels. The PCB was based on a low cost triode-pentode driver tube and 6L6 family of output tubes that are available around the world. The power supply capacitors were 450V stacked to allow for 600+ B+ voltages. Push-pull 6B4G class-A amplifier. Push-pull KT88/6L6/EL34/2A3/300B amp with "universal" driver / power supply PCB. 813 single-ended triode amp with microprocessor-controlled power supply. 829B triode-mode SE amp. 2-8 watt push-pull amp using 7044 computer triodes. EL802 push-pull single-stage "spud" amp experiment Nov 15, 2007 · The NAT Audio Magma, of course – designed to be the most powerful tube amplifier ever built.* The NAT Audio Magma is capable of blasting its raw power at 4 or 8 ohms with a frequency response of 10-10,000 Hz. To produce this power the Magma relies on three different tubes: the 6N1P-EV, the 6N30P-DR, and the Eimac 450TH. When it comes to power tubes, there is nothing around that sounds anything like an RCA blackplate 6L6 in a great guitar amp like any old Fender and many others - there is a reason of market demand some old tubes go for big dough, same as with many classic HiFi tubes, I presume - or could stereo amps be much less affected by inferior modern bottles? PRICE!! While new 7027A's are $95+ each and 6L6GC's are $75 each (or more), our 6BG6GA's are only $18 each!!

When Pink Floyd started out in the psychedelic mid 1960s, they were playing clubs, led by Syd Barrett on guitar. But once David Gilmour took over, they evolved into a stadium-rock band and began crafting extravagant concept albums. I'm trying to learn the basic theory behind switching power sections... trying to get an idea of how modular any change would be. Using the schematic of my modded 6G2 as the example - what tweaks would be required to switch the power section from 6V6 to 6L6, and have the amp working without issue? Oct 11, 2015 · The 6L6 Transmitter is basically a crystal controlled radio frequency oscillator. C1, Coil, and C2 form a tuned matching circuit used to match the high impedance of the oscillator circuit to the low impedance of the antenna. The 2.5 MH choke connected in series between the 300 Volt DC Power Supply and the Plate (pin 3) of 6L6 prevents RF from ...

The 807 is a beam tetrode vacuum tube, widely used in audio- and radio-frequency power amplifier applications. 3 Differences from 6L6. 807s were used in audio power amplifiers, both for public address and Hi-Fi application, usually being run in push-pull pairs in class AB1 or AB2 giving up to 120 watts of usable power. The plate voltage limit ... comprise the power amp. The rest of the components are used in the preamp. Figure 9: Preamp and Power Amp Circuitry Once all of the potentiometers were soldered into the appropriate places in the amplifier circuit, they were affixed to the front of the chassis and their knobs were attached. The front of the chassis can be viewed in Figure 10. Today we are looking at the differences in the two main types of "power amp" tubes, 6L6's and EL84's. There are significant differences in the sound produced by power amp tubes labeled "6L6" and "EL84" - and when shopping for a guitar amp you will want to consider these carefully according to the style of music you are playing. 6L6 Tubes
As we said above, the Class AB Amplifier is a combination of Classes A and B in that for small power outputs the amplifier operates as a class A amplifier but changes to a class B amplifier for larger current outputs. This action is achieved by pre-biasing the two transistors in the amplifiers output stage. Total number of schematics listed is 187.

Fender has been using them since the 1940s and since then there have been many others who have designed hugely popular tube amplifiers that rely on the 6L6 tube types for their tone. Unlike the EL34 power tube, 6L6 tubes generally sound a little cleaner and tend to have a bit more beef in the low end as well as more bite on the top. Some ...
An amplifier is an electronic device used to increase the magnitude of voltage/current/power of an input signal. It takes in a weak electrical signal/waveform and reproduces a similar stronger waveform at the output by using an external power source. Depending on the changes it makes to the input signal, amplifiers are broadly classified into Current, … TubeDepot carries a selection of 6550 / KT88 / KT90 Power Vacuum Tubes.

Buffalo wild wings wet wipes ingredientsThis DIY guitar amp is the answer to the design question: what kind of amp can I build with a power transformer designed for a one or two-tube radio? The very limited filament and high voltage current provided by such a transformer rules out anything like a conventional design. This is the D&A model Phantom 500 amplifier. This unit was a two stage amp, with an advertised power output of 500 watts on AM and a whopping 1500+ watts on SSB. The unit pictured was the "old" version sporting a gray cabinet. Like the Maverick 250, this amp was also offered in a The 813 followed on the heels of the famous 6L6 beam power tube, which was the first power tube to use the electron beam principle. The 6L6 was released in 1936 and was first announced on page 50 of the May, 1936 issue of QST magazine. This was the first amplifier Marshall® ever built, based off of the 5F6A circuit. Favored by blues and rock guitarists, this amp can produce a warm sustain and elegant clean tones, with a pronounced rectifier "sag." Played by guitar greats such as Angus Young and Gary Moore. If playback doesn't begin shortly, try restarting your device.

A DIY hi fi preamp design from 1954. Note the very sturdy parallel-cathode-follower output (the 12AU7 section). This could probably drive a 10K load pretty easily.
The negative feedback circuit is identical in the 6V6 and 6L6 AB763 amps so the lower voltage supplied by the 6V6 power amp leads to about 25% less negative feedback than the 2x6L6 amps and 47% less than the 4x6L6 amps. This is one reason the Deluxe and Deluxe Reverb get dirtier at lower volume settings than the 6L6 AB763 amps.
