Transformer
We have introduced R core for this new audio output transformer. R core is a new type of magnetic core for transformer and now increasingly used for power transformers because of its performance advantage over the other conventional magnetic cores. Both transformers for push-pull and for single-ended are available.

Application Notes using R core Audio TransformerSV811-3 Single-Ended 12W Monaural Power Amplifier
Building amplifier project using RC-20 Interstage Transformer, RW-20 Single-Ended Output Transformer, and MS-1 chassis. This is a very beautiful tube amplifier with power tubes SV811-3 brilliant like electric globe. This is a high power amplifier that outputs 12W being 50% more than 300B. The main feature, however, is first and foremost easy to build by its configuration of both the power supply voltage less than 500V and the inexpensive parts commonly available in the market.
2A3 Push-Pull 20W Monaural Power Amplifier
Building amplifier project using RC-20 Interstage Transformer, RX-40-5 Push-Pull Output Transformer, and MS-2 chassis. This amplifier realizes 20W high power output and excellent performances (low distortion, wide bandwidth, high output, and low noise level) that are difficult to be achieved by the single-ended amplifier. The main feature is well balanced sound quality based on straightforwardness and well-developed mid and low range particularly characterized by interstage transformer coupled circuit.
Matching Transformer
for SEPP Amplifier
This is a matching transformer for SEPP amplifier using vacuum tubes or
SIT. This transformer converts the low load impedance of the loudspeaker
into the best matching impedance for SEPP amplifier. The primary impedances
72 ohms and 128 ohms are available.
By employing this matching transformer, you can realize,
of SEPP and vacuum tube OTL amplifiers.
