toydetective became tubedetective in 2019. During my 35 years as toy importer/exporter I intensively travelled Europe and many other world countries. When possible I visited any electronics shop I could find to search for vacuum tubes, a hobby that became a passion. From a collector I gradually became a hoarder, but it is time to sell part of my collection. All tubes are tested, unused (except for testing ;) so check this audiophile treasure trove regularly!
