Group C, bifilar wound double C-core output transformer with 10K primary impedance and 4 & 8 Ohm secondaries for 211/VT4-C or 845 in single-ended operation, 240mA standing current, 50 watt, flash tested to 5,000 volts, Size 115 mm x 102 mm x 136 mm, mounting holes centre to centre 87 mm to 84 mm both sides. Prices are for ONE transformer.

Up to now the recommendation has been that all Audio Note™ silver wired bobbins should only be used with Nickel C-cores as the performance improvement is tremendous, however, with the emergence of the new AN Ultra HiB the sands have shifted, so whilst in general it is still my view that the nickel cores are the best sonic investment one can make, the Ultra HiB has changed the position to the point where the Nickel is really only a good investment, if there is silver in one or both windings, the AN Ultra HiB should be considered as it provides a slightly gentler character with a better/deeper bass character than the nickel irons, bear this in mind when you plan your project.

Believe it or not, I have tried to keep the prices of the above transformers as low as possible, and I would like to remind all of you reading this, that when you consider the fact that a Japanese made ONGAKU™ output transformer would cost at least 3 times as much as the best version of one of the new Audio Note™ silver wired 211SE output we offer above, and that in addition to this our output transformer has not only a better C-core and general specification than the original ONGAKU output transformer, so whilst these prices may seem expensive, the product offered is incomparable to anything on the market both in terms of both sonic and technical quality.

The Audio Note™ output transformers offered above differ from the ones used in production amplifiers in two key areas,

1. Output transformers in such amplifiers as the ONGAKU™, KEGON™ or BARANSU are carefully matched to three different parameters (I am not at liberty to tell you more than one, frequency response, the other parameters are proprietary, as I do not want our competition stealing more of our technology and ideas than strictly necessary).

2. We use the C-cores with the best/neatest lamination alignment in production, and whilst this makes little difference to the sound, it is important to appreciate this fact.

All the above transformers are supplied raw in the sense that they are unpotted and with flying leads.

We shall shortly be adding a range of parallel single-ended 211/845 output transformers, so keep a look out for them.

As a rule delivery of the above output transformers is from stock, but dependent on internal usage delivery time can occasionally occur, especially the new custom made AN Perma Nickel cores may be on very long delivery, which can be as long as 16 – 18 weeks, we will normally try to tell you if a transformer is not in stock how long the delivery is likely to be, but in the case of the permeable materials production processes are very complex and problematic, so just beware.
