LampizatOr 211 Amplifier

Description:

The amplifier is the muscle of the music system, if the DAC is the brain and heart.  During the years with Lampizator DAC we realized, that many of our customers need an amplifier, and they are very concerned that a decent tube amp cost in 5 figures Euro.   I believe that this amplifier offers terrific value: surely it is not cheap, 8900 Euro is hardly pocket change but it is the lowest price for which a decent amplifier can be built from parts that were not stolen, but actually purchased with an invoice. There are no miracles - if someone offers cheaper power amps of this class - he is either selling them under cost to get rid of them or using children slave labor in far away camps. Or simply the technology has too many compromises like underpowered transformers, underrated voltage specs, undersized caps.


I offer good price because the amps share half of their parts with the lampizator DAC - the front panel, the caps, sockets, small tubes, all input and driver circuits and supplies. (The amps have part count of 330 ! )


The amplifier employs only the most radically “kosher” circuit features like:

Single ended triode operation from input to output

Pure Class A

Zero feedback, neither local nor global

Zero solid state parts in audio circuits

Unregulated and overspecified supplies

Separate transformers for each task (three in total per side)

Short signal path - from RCA to pot - 2 inches of silver wire, same  from pot to first tube, same from the first to the second tube and a hop across one capacitor to main tube without additional wiring.

Power tube bias current is monitored on analog needle meter

No need for triode matching as the bias is set manually.

There is a possibility to compensate aging drift on power tubes

Pre-heating operation mode for tube (and for electricity saving)

Pots can be bypassed completely by toggle switch for the “power amp” operation mode.

The amp is built around simple concept: to make it “as well made as sanely possible”. Without Gucci crazy stuff but otherwise - without compromise. 

So the power tube is the best I know of (except the insanely unavailable original WE211)

The power supply has oversized transformer, one separate transformer for every task - one for 211, one for small tubes and one for all heaters.

The small tubes have choke supply, and separate PSU for every half of the two triodes. The schematics is the best I know of - based on the experience with tens of 845 amps I rebuilt and the GM-70 sister amp that we sell.

The big tube has silicon rectified PSU. The small tubes - have very good tube rectifier. 

211 has its own huge choke as well. 

Signal "path" wiring is super short - 4 inches in total. 

All parts are very good, over-specified, used well under their limits and so on. 

Bias is adjustable by user.

And whats most important - the output transformers are of first class  - the famous OGONOWSKI type.

I decided to use very well tried schematics - 80 % is my Lampizator DAC scheme plus the power tube circuit .


The amp sounds VERY powerful, with strong bass, pure trebles, scary close mids, deep 3-d soundstage - all I wish for and more.

I hope there is nothing that can fail, even after 30 years of service.

211 is an alternative to our GM70 amp

Not that 211 is a better triode than GM70, but it appeals to those people who simply can’t stand having a Soviet product. Like many customers from the former Soviet Block including Poland. They would rather have “Polish Ongaku” than “Polish Soyuz”.

Its introduction will re-define the price point for owning the real deal 211 SET mono amps that sound as good as 5 figure amps on the market at less than half price. We are aiming at people who would normally buy a stereo 300B amp, but from us they get not only monos instead of  stereo integrated, not only 22 WPC instead of 8, but also the super cool super mean looks of the GE211 triode.

All our know how, experience, passion and resources went into this creation. Not to mention all our reputation at stakes.

The only reason I mentioned Ongaku here was the similarity of the triode, but there is nothing at all that I copied from Ongaku schematics. These amps have nothing in common except the triode itself.

We use PSVANE triodes from China (the Chinese best ones) which are reliable, and fantastic sounding. In comparison to GE NOS the Psvane sounds exactly equal. The user can purchase on ebay the NOS GE. I like 211 better than any 845 or 805 I heard.  Comparing the 211 to GM-70 they are about equal to copper GM70 variant.

As of June 1 2013 the 211 is available as off-spring variant of the GM-70 monoblock amps from LampizatOr.
