  1. I have 'inherited' a pair of KLH Model Thirty-three speakers. They sound quite nice.... except that there is nothing coming out of the woofer of one of them. Nothing at all. I saw nothing damaged or broken during a superficial visual inspection of the wiring and soldering (once I unscrewed the woofer from the cabinet). Could you help me diagnose the problem, verify the diagnosis, and fix it? I can imagine two obvious potential issues: 1. the woofer is bad and needs to be repaired or replaced; 2. the caps are so old (or at least one is so old) that it/they form(s) a break in the circuitry. Are there any other potential issues I should be looking for? What is the best way to confirm or reject either issue above? I could use a Volt/Ohm/Amp-meter to measure between the two contacts on the woofer, while playing something (the amp is an old British great: a Creek 4040S2). Could I tell from the readings I get if the problem is with the woofer or with what is wending its way to the woofer on the wires? (sorry, couldn't resist :)). Similarly, could i measure something on each capacitor in place to determine if that cap is a break in the circuit? Would it make sense to disconnect the woofer in the 'bad' speaker and connect it in parallel (or perhaps in place of) the woofer in the good speaker. If i do that and the woofer from the bad speaker is still silent -- does that prove that I should just throw it away, or is it possible that it can be repaired? If it can't be repaired, would someone be able to recommend a source for a replacement? WIll I need to buy a pair if I'm replacing one? If there is a better way to diagnose the problem, and/or some other likely cause than the two i could think of, please enlighten me, As far as I could see from these pages, the only (non-cosmetic, functional) repair one normally needs to do is to replace the caps. Are there other things I should check? Thank you for your noob-friendliness, truly THANKS! --scott UPDATE/EDIT: The woofers are connected to the wiring by simple wire-nuts, so it was very easy to swap them. When I did this, I discovered two things, neither good: 1. the woofer that had been silent continued to be silent, and the woofer that had previously worked continued to work. However,it seems that the midrange/tweeter in the formerly "good" speaker wasn't working after all (while the one in the enclosure that originally housed the 'bad' woofer continued to work fine). The end result of this swap, therefore, is that I have one speaker which seems to work just fine, and one that is completely silent. There's nothing obviously physically wrong it.... but both cones make no sound. If i can do anything which might correct this, I am very open to suggestions, THANKS!
  2. Hey all, I'm a newcomer to the forums. I just inherited my parents' pair of KLH Model Thirty-Threes. I'd like to put them back in working order and found this forum while searching the web. The ultimate goal is to have a nice sounding little system set up so I can play my childhood LPs for my new baby daughter. Looking back on my childhood, listening to Peter and the Wolf and Bill Cosby's Why is There Air? just wouldn't have been the same if my folks had played them on an iPod docking station. I want my daughter to know there is a rich and deep world that predates the zeros and ones of the digital age we find ourselves in! (Sorry for the little rant, I have only just recently discovered my latent Luddite tendencies, so I'm a little excited.) I didn't find a FAQ section or the like. Can anyone direct this absolute beginner to a good starting place? That's the first question. Second question is, any recommendations on a fairly common, fairly inexpensive receiver model or brand that would be a good match for these speakers? (Remember, I'm a newb. Overly technical information will be wasted on the likes of me.) Thanks for your time. Looking forward to being a member of the community!
