Hi, Iam new at this and I have a few questions, Iam not really sure if this is the right place to post this if it is not can you tell me where I can get the information I need? At my dad's office they did some cleaning and he found a DE Plan 300 speaker which I don't know if it works or not, can you tell me how test it and use it? also he found an old McIntosh Preamplifier Model C28 which I have no idea how to use can you tell me how to use all of these what extra things I need, where can i get them etc. Again if this is not the right place feel free to tell me where to post it, it can be even another site. Thanks
