A Versatile Affordable SE Solution!

The ST30SE is a medium powered integrated amplifier offering warmth and colour in an ultra-smooth way to delight almost anyone who is sensitive to the many harsh and clinical presentations offered by others. The ST30se offers absolute listening quality through simplicity of design and pure “Class A” operation. This is achieved by using a very simple design, high quality construction and our unique transformers designed and manufactured “in house”.

Previously, affordable Single Ended designs have been low powered at around 9-13w. The excellent new KT150 valve enables more than double this power for the same cost.

The all-important high definition drive circuit for the KT150 output valve is achieved by using the superb 6SN7 valves in “Cascode” mode to get the best qualities of SE* without the drawbacks of flabby bass, hum and low power that many designs suffer.

The ST30se is optimised for Triode as well as UL operation. 18 Watts being ample for most situations. Especially with our new “Full Range M” or MFV3 speakers and other designs such as the classic Tannoys, the ST30SE will work well with any speaker of about 90dB or more.

Good sensitivity from the built in “passive” pre amp ensures good results from virtually any type of input.

The “easy bias” meter enables simple checking that the KT150 is at optimum performance, the meter also gives an indication of the output power. Very useful when you may need to know if you are likely approach the maximum available power.

Reviews

Service good, apart from the carriage cost, which I thought was too high, at £10.95. The KT150 valve was intended for my Stereo 30SE amplifier, on which I seemed to be unable to get the bias high enough. However, on checking again (before fitting the new valve), the bias was far too high, and I was able to adjust it correctly! Strange. The Stereo 30SE amplifier is very enjoyable to listen to. Apart from being much lower powered, I would say it sounds as good as my Primaluna Dialogue Premium HP power amp and Conrad Johnson PV10A. So, to summarise. I didn't need the new KT150 this time ,but it will no doubt be needed at some future time.
