Welcome. Over time various pieces of audio hardware come my way, some very ordinary, some quite extraordinary but maybe not very good and sometimes extraordinary AND good. I will occasionally put up interesting and/or curious pieces of audio hardware; their construction, repair and restoration may also get a mention as well as subjective sound quality associated with them; some of it may be helpful. or interesting ... or both. I am now starting to add some guitar (instrument amplifiers) and maybe other associated items. They will have a separate tab and sub tabs.
