Space-Tech Laboratory 300B-100W

Here’s a unique chance to get an amplifier design with the finest purity sound in mind of the 300B with a giant output power capabilities of 100 watts rms per channel in 8 ohms and 200W rms per channel in 4 ohms  all done in single-end. This amplifier is all hand made point to point wiring.

This amplifier have been upgrade to the last version of transformer in may 2020 and completely check by the manufacturer in may 2020. It’s like buying it new at a very good price. I required , at buying, I can follow the proof of the tuneup by Space-Tech.

Why this amplifier is so special, because it’s single end 300B , in the driving amplification (voltage) but without output transformer that give you normally 8 watts. Instead, it’s a OTL (output transformer less) with zero feedback design (most pure sound) with enhanced power output and wider frequency response that cover 2Hz to 100kHz. You can drive speakers with the 300B and in single-end without the need to buy a high efficiency speaker with this tune SET-OTL amplifier 300B with 100 watts rms/channel in 8 ohms and 200W rms/channel in 4 ohms. It’s the opportunity to have 300B with any type of speaker.


How it’s sound : Rich, smooth sound and airy sound and a midrange to die for !

If you know Space-Tech Lab there really isn’t much I can say too you that you don’t already know about these products. Unmatched sonic capabilities to anything else I have come across in my travels of hifi gear including very well know brand.
