So to upgrade(rebuild) the crossover yourself, are the values stamped on the caps? I'm looking to replace the caps on my 86's but would like to buy the caps first so I only have to open 'em up once per upgrade. Getting the capacitance value is easy enough, someone posted the schematic, but what are the voltage ratings of the various components? Are the crossover gurus willing to share this info or is someone else who has done this willing to share? I'm all for DIY when possible. -Mark

A great deal for $250. Wonder what it will go for?

Amen to that. I have a set of 6' braided cat5 teflon cables. What a pain. Now I've got two lengths of 14ga zip wire. Sounds great. I've still got the "audiophile" CAT 5 though. $100 for 2, 6 footers? Let me know if you get a buyer! How (why) did you pay over $100 for a few lengths of teflon CAT5? Why are these cables and tubes a no-no?

I like the look of the cane grills and would gladly trade my black one's for them but you're in Toronto and I'm in Colorado. Don't think it would work - I don't trust UPS or Fed-Ex to be careful with them. Regards, Mark

Pardon my ignorance, what is a shorthorn and how is it different from a K-horn?

Glad you found a scematic. I found a source for a manual for your unit but he needs a scan of mine first and it is packed away at the moment (in the process of moving). The meter you see is really handy for setting balance and bias. I believe it is only on the kit version of Fisher amps. The person who put mine together some 40 years ago did a superb job. The speaker cables are one's I made when I was caught up in the "high end cable" frenzy. They are braded teflon insulated CAT 5. Supposed to be the nuts but I really can't tell between them and good old 14 ga zip wire. I was running a center speaker to test my newly aquired CW's. Since one had a blown tweet I could only run one. The CW's are more efficient then the mains and so outpowered them. It sounded wonderful. I have since repaired the tweeter and am now running only the two CW's. I am seriously blown away. They rock. I listened to a DVD of a 1982 concert of Stevie Ray Vaughn and Double Trouble last night. I can't describe how good it sounded. I hope you have luck with your amp. I would love another Fisher for a spare. They made an outstanding amplifier. -Mark

I listened to a pair of '86 Cornwalls before buying mine. They were the best speakers I had ever heard and I had to have them. If all later CW's are naked then I think I will listen to them that way for a while before making any changes. What do you mean by "smoother" bass? As measured with an SPL meter or is it a subjective improvement? Were you able to do an A/B test or did you modify both speakers at once? Are the stock crossover's that bad or is there some degradation of the componenets after 20 years that you hoped to remedy by rebuilding them? Thanks for your comments and suggestions. I am still at the early stages of listening to and appreciating these very fine speakers. They are incredible. -Mark

I have a pair of '86 Cornwalls. I bought them from the original owner who swear they have never had themn apart. I had the horns out for some minor repair and noticed that there was NO stuffing in the box. None. There was a brace from front to back below the midrange horn. The crossover was screwed to the back - an inductor coil had come loose and was hanging by it's wires, I glued it back to the board. But the inside was otherwise bare. Is this unusual? During a test listen through one speaker, the other needed a new tweeter, it sounded very good. The bass was thumping me in the chest and the sound was exceedingly clear. Are later Cornwalls naked inside? -Mark

The way you were instructed to hook it up doesn't sound right to me. A manual would make things easier, I'll see if I can find one. Your unit has a lot more inputs and outputs than mine. Mine is pretty straight forward. I'll include a pic in case it gives you any ideas. -Mark

Hello. I'm a new member, old lurker. I have a similar amp, KX-200. I think it is the kit version of yours. The orange drops and rectifier replacement sound like it was one of FisherDoc's kits. Have you tried him as a resource. I have found him to be extemely helpful in answering questions on my amp. He's slightly controversial on some BB's, not sure how he's received here but thought I'd mention it. -Mark
