Dynaco ST120 Stereo Amplifier This auction is for a Dynaco Stereo 120 power amplifier in original condition. Cosmetic condition is very good, showing no major defects. I originally purchased it with the intention of upgrading it to match the PAT4 I upgraded, but found that it sound so good, there was no point to upgrading it. I have not opened it up. I have used it for many hours of excellent listening pleasure. It does not have any apparent roll-off on the bass when used with Dynaco A25s as one might expect from an amp that is at least 50 years old. Buy it and listen or buy it and upgrade it. Its winner either way. I have a signifcantly upgraded PAT4 preamp listed, also. Click on See other items in the Seller Information box.
