| Diy "recepies" for speaker wire anyone? There's at least one good website with DIY info for cables, but I can't find the URL at the moment. My reply may generate a few arguments, but here are the basics. If you assume the speakers sound best connected directly to the amp, then you want ... | |
| Worst Audio Injury !! Worst audio injury was to our dorm's cleaning woman when I was in college (1972.) I had a home made amp that I thought needed a cover to keep prying fingers out, so I bent one up out of aluminum flashing, like an upside down "U" (only temporary, o... | |
| foam on speaker delaminating. Fix it ??? Try www.newfoam.com, www.woofer.com/woofer, or www.steppaudio.com. They make repair/replacement kits for surrounds, maybe they will have something you can use. I've never had to use their products, but comments I've heard were favorable. I have re... | |
| Cable Question ?? One reason for cables directionality is that one end has an extra outer ground shield connected to the plug shell, while the other end doesn't (both ends will still have two connections for the signal, whether there is an extra shield or not.) The... | |
| Built your own speakers ? I have to concur with Keis. I rolled my own speakers 3 or 4 times, the first 30 years ago and the last (subwoofers) about 10 years ago. I have a full woodworking/metal shop, and a complete electronics shop, plus even better at work. I still have a... | |
| Can speaker cables damage amplifiers? Wow, have we hit a sensitive area. In trying to answer the previous readers questions, I have tried to avoid the use of technobable, since this forum is intended for a general readership. However, since I wasn't the first to bring in jargon, I'll ... | |
| How can I measure power draw? Bob's solution is a good one, and not all that difficult. But, if you really want to know without any trouble, Allied Electronics sells a nice digital wattmeter, just plug in the equipment and read watts used. Regret to say the cheapest model is $... | |
| Can speaker cables damage amplifiers? There's so much here, I hardly know where to start. First, in my opinion, if an amplifier can oscillate just because of using a certain brand of speaker cable, either the amp, or the cables, or both, are poorly designed. Second, oscillation is a s... | |
| Preamps I just bought a used DR-6. There are several versions relating to input options (bal vs. unbal); check first before you buy if that's important. I won't comment on the sound, since I haven't used it enough yet, but the first thing I noticed when I... | |
| B Stock Or Grey Goods, How to Tell? To answer your question about "B stock", that usually refers to equipment that has been refurbished by the manufacturer. I don't believe serial numbers would be recorded during this process. Since most things sold on ebay are already used, that ma... | |
| Bad Transformer? Assuming the tubes went dark because the filaments lost power, and not because the amp normally runs with the plates red hot, I have to respectfully disagree about the power supply being the culprit. As I recall, this amp uses AC for the filament ... |
