6L6 is the designator for a beam power tube introduced by Radio Corporation of America in April 1936 and marketed for application as a power amplifier for audio frequencies.

While all 6L6 types are pin compatible with one another, some amps are designed only for the higher powered 6L6GC. When you replace your 6L6, you should make sure that you replace with the right type. Common Types and their rating. There has been many 6L6 variations, but the most common ones today are: 6L6GC - 30W version. Can be used anywhere

2009年2月5日 · Pin 1 and 6 aren't connected to anything on a glass 6L6 (pin 1 is connected to the metal envelope on a metal 6L6). So these are often used as tie points. So if you look at the bit of the twin layout below, you see there is a 1.5K resistor between pins 1 and 5 (5 is the grid), and the output from the previous stage attaches to pin 1.

2021年3月25日 · Just trying to confirm pin 1 and 8 in my build. I'd like to be able to swap in 6L6/6CA7/EL34. The amp is cathode biased. Do I connect pin 1 and 8 at the base or do I run pin 1 direct to its own ground. With the former configuration, the suppressor grid will be at the same voltage of the cathode, and with the latter, it will be at ground, correct?

The best deal around in 6L6 family tubes may be the Russian 6П3С-Е (6p3s-e). Be sure to buy thoroughly tested stock from a reputable dealer.

2006年3月13日 · The "spare" pin to use on octals (for screen Rs, etc.) is 6. This is N/C on 6V6, 5881/6L6/KT66, EL34, and 6550/KT88. Also, it' s safe to connect pin 1&8 on all of these (and somewhat necessary for the EL34 )--mark h

In Europe it were the pentodes AL5 (4Vf) and EL5 (6.3Vf), in the USA it was the worlds first and most famous beam-power-tetrode, the 6L6. First it appeared as metal tube, then in several …

2012年12月18日 · In all glass versions of the 6L6, pin 1 has no connection to any internal element, so it is safe to use as an anchor point on the valve socket. Very early Fender models could use the original metal 6L6, but later models required a higher-rated 6L6 version, or a 5881, which freed up pin 1 as a tag point.

The 6V6 receiver type of beam tetrode with which it shares pin connections is a derivative. This valve was mainly used for audio amplifiers. The 807 was based on the RCA type 6L6 beam tetrode, which had a long, fairly thin, anode and a carefully-aligned grid structure. The 6L6 employed rapidly-accelerated electrons and short electron paths.

The 6L6 is an 8-pin "octal" beam power tetrode tube found in the power amp section of many guitar amps, mostly in sets of two or four matched valves. It has a 6.3v heater filament and can dissipate 30W.
