A Little Legend of the 2A3 Sound from feed-back. My Presto 41 uses the 2a3 Tube. It sound better than any other limiter I have ever used.. Rock on 2a3 and the Presto is probably more rare and was used to master most of the really old cool mono recordings.. Years before the Fairchild.. It sound like silk with creamy harmonics abounding.. The electube realise the sound and song. In its highest intensity. The item “Pair Triode Power 2A3 Tube Vintage SINGLE PLATE Foremost A1 TRIODE Amplifier” is in sale since Tuesday, July 21, 2020.
