The new 2A3-PRE uses the special shaped glass 2A3 valves/tubes made specially for us. We also use the same valve rectification as used in the MC300-PRE circuit along with a very similar circuit for the amplification side. We also use the internationally famous branded components and input transformers to produce a high quality and outstanding valve preamplifier.
