| Replacing 6550s with KT 88s I wouldn't be a bit surprised if brand new KT88s sounded better than end-of-life 6550s, of ANY brand, in ANYONE'S system. Happy listening! | |
| What is a high end stereo SUPPOSED to sound like? I couldn't have said it better: ( http://www.ultrahighendreview.com/the-sound-of-one-hand-clapping/ ) If this is/was a repeat, sorry! | |
| When to repair or replace speakers? A very talented man, of many passions. Most of which; I share(though I'm forced to pursue them on a truncated shoestring). I haven't spoken to him a great deal, but have always enjoyed the conversations. | |
| Hafler DH300 Monoblock forever? Hafler made a bridging kit for the DH-200. You can find the manual here: ( http://www.hafler.com/techsupport/pdf/DH-202_PC-7_bridgeKitForDH-200.pdf ) Your amp probably has this installed. If you can recognize the circuit(the PC-7 board), inside yo... | |
| Fuses that matter. @metro- Perhaps(If you listen to COWS, or their BY-PRODUCTS) | |
| When to repair or replace speakers? IF your drivers are the problem; I second contacting Bill at Millersound. He'll insure they are as close to their original parameters as possible, when rebuilt(very important, performance-wise). | |
| When to repair or replace speakers? It's possible that the voicecoil(or former) is rubbing the magnet plate or pole piece. It's important, when trying to determine if rubbing is occuring, to insure an aligned movement of the voicecoil in the gap. The driver should be out of the cabi... | |
| Fuses that matter. @Ccstevenson- Well Stated! | |
| When to repair or replace speakers? A bad power supply filter cap(power amp) sometimes results in the same symptoms. That can sound exactly like a voicecoil bottoming out. If you can get to the built-in amps: look for signs of leakage around the electrolytic caps. | |
| Risk using amp Wattage than speaker rating? YES- You've both gotten the point, precisely. For those customers that came in with toasted tweeters; I gave a little clipping demo and sermon. I also had a little tweeter protection circuit(that I built), comprised of two zener diodes, hot-melt g... | |
| Risk using amp Wattage than speaker rating? Having repaired speaker systems for a couple decades; I can assure you that high powered amps can damage low power rated systems. Crossover capacitors are rated for only so many volts, and lots of manufacturers skimp there. I've lost count of how ... | |
| MARTIN LOGAN TRIPLES THEIR PANEL REPLACEMENT @Mateored(et al) This is just a History lesson. I am posting it to all regardless of party . I bet I know who won't read it -- those afraid of the truth. It is history and nothing can change it. But Obama is trying, by campaigning on "how bad the ... | |
| Replacing 6550s with KT 88s WOW- Singapore! I'll bet tubes ARE expensive over there. I've purchased quite a few Siemens tubes(in the past 12 years), from this vendor in West Germany. He's very reliable and sells excellent tubes: (http://myworld.ebay.com/audiotubes_de&ssP... | |
| Replacing 6550s with KT 88s I had been purchasing NOS Sylvania 6550's, from Upscale, until his supply ran out. Went to the =C= and felt I was missing nothing(at that point). Those had over four years on them when replaced with the NOS GE 6550A octet. Thus- I can't offer a va... | |
| Replacing 6550s with KT 88s If you replace all of the tubes at once(pre and power); you won't know what tubes made what change, or to what degree. Just a thought: replace the preamp tubes first, and listen for a while. Put the old pre tubes back in, swap out the power amp tu... |
