2018年4月28日 · This article from respected author Ari Polisois deals with a single-ended amplifier with enough power to drive even the most difficult speaker systems - delivering 50W per channel.

2010年7月20日 · The 6C33C-B is an attractive tube; 15-20W output, relatively inexpensive at $16 each in Russia and, at 200V, relatively low voltage. The downside? The 6C33C-B requires a relatively high current, typically 220mA at 200V. And it has stinkin' hot heaters. Many of the published 6C33C-B circuits use variable bias, and globs of feedback.

2018年1月2日 · Operating point of the 6C33C is set at 190 Volts and 170 mA. So it is driven less hot than most designers do to obtain maximum output power. It still yields about 10 Watts which is more than sufficient to drive my speakers and most tubefriendly speakers as well.

2017年2月13日 · If midrange is true direct-heated triode without the excess bloom, bass has the speed, grip, tremendous impact and shocking growl that lives somewhere between a good transistor amp for transients and control and the saturation of a high-power p/p valve machine. Iron and velvet: This amp sings freely and let’s go with a flourish.

2020年8月23日 · I'am interested in building a 6C33C SE amplifier and now I'am looking for a good and simple schematic. I found this after a long search in the forum: but also different schematics with different driving stages and power supplies.

The Spark V is our most affordable single-ended triode tube amplifier for serious music lovers. Low distortion, excellent dynamics, holographic sound, warm yet detailed in the midrange, fast and powerful bass. An amplifier for advanced music lovers who …

2017年6月2日 · While the 6C33C can be used in OTL configuration, Fluxion’s AV-7 is a traditional transformer-based amp. This amp is a true integrated design – it has three gain stages (achieved with only four tubes), and two switchable line-level inputs. The two initial stages employ a single dual-triode each, so retubing should be fairly economical.

Here is a new Lansing Audio Brand 6C33Cls-8 integrated stereo amplifier. These are excellent sounding amplifiers with huge transformers. This amp puts out some amazing sound and has more than enough power at 16 watts per side. It uses 2 tube 6C33C, 2 tube EL34 Driver and 1 tube 12AT7 pre. Quite heavy at over 105lbs.

The Storm is a completely new 6C33 design with a new power supply, new pre-driver stage and new output transformers. The Storm is our most affordable single-ended triode tube monoblock amplifier with an exceptional and attractive price-performance ratio.

6C33C is a two-plate power triode. It can continuously dissipate up to 60W on the plates and needs 6.3V, 6.6A for its heater. 6c33c is a current-source tube, originally designed for regulated power supplies. It is best utilized with idle current of 200-250mA.
