The lower-powered 6V6 was better-suited for average home use, and became common in the audio-output-stages of "farmhouse" table-top radios, where power pentodes such as the 6F6 had previously been used.

Sep 1, 2013 · Wikipedia and other sources show the 6V6 as a beam-powered tetrode, yet other sources (including some old tube data sheets) list it as a pentode with three grids. further, most of the tube data sheets say it has a screen, but i've come across at least a couple things online saying that it, in fact, has a supressor, not a screen. i get the ...

Oct 25, 2024 · Suggest starting with the pentode biased for lower gain, experiment swapping different values of R Anode, G2 R and cathode R increasing gain to find the distortion & tone to your liking.

Apr 29, 2005 · So a pentode is designed for a high Mu (G1 to G2), 10 or 20, for good power sensitivity. In a triode, current falls when plate voltage falls. You want a low Mu, like 5, to reduce this effect. 6V6 Mu is 10.

Aug 15, 2015 · Frannie -- You can certainly use a conventional pentode type 6V6 output transformer with those tubes strapped for triode service. For the typical circuit that would produce (about) 12 watts from push-pull pentode 6V6s, expect about 3-4 watts in triode mode.

6V6 S is a beam power pentode with octal base and a maximum plate dissipation of 14W. It has fat low end and full mid tones with very good tone separation and a smooth, clean high end. Known to be a very powerful 6V6 due to its robust construction.

Apr 3, 2019 · Out of interest, I want to build another SE 6V6 amp with these parts, with a pentode in the preamp. I have come up with a first draft of a schematic, and also with some questions for anyone interested in this project.

Triode operation (g2 to anode) is relatively docile compared to pentode operation, where the anode can go to -200V with respect to the screen on low wave cycles. If the tube is made for such conditions, it is not really on that Ig2 (or the screen dissipation) will be a problem under triode conditions (within maximum specs, of course).

The TAD™ 6V6GT-CZ has been added to the TAD Premium line in 2020. It is a glass envelope beam pentode having a plate dissipation rating of 14 Watts with convection cooling. It is intended for audio frequency power amplification service... Welcome back!
