VinylSavor: Tube of the Month : The 211 / VT4C

Jul 22, 2012 · The 211 is a serious tube, not only due to it's physical size. It is about 20cm high with a diameter of 6cm. It requires high plate voltages. To get full power it needs 1250V. It is also demanding in terms of filament power: 10V at 3,25A. The maximum plate dissipation is 75W. With the 32.5W filament power this means it …

Nov 16, 2009 · 211s will give more power, but require >1000V and their characteristics make the design of the output transformer tricky *, to say the least. Those two things mean that it is expensive to do a good 211 amp.

Jul 05, 2011 · About the least complex 211 I've seen is the design on PAE's site: PAE 6C45 --> 211 amplifier I built a version (with a very different power supply design) with a more modest B+ (825vdc) that I've been enjoying.

For power, we will bias the 211 to the lower power side at around 12 WPC Pure Class A. Instead of pumping it to over 20W like some manufacture would do. We want the most silky, the most refine type of 211 sound quality that beyond people have heard with 211s.

Nov 16, 2009 · I would only choose the 211 if you absolutely need the extra power. The 845 (a very close relative of the 211) is arguably a better choice in any case. * The fabled Ongaku uses a circuit trick to restore the droopy HF response because of the difficulty of designing a wide bandwidth, high impedance, high(ish) power output transformer.
