| testing a crossover imhififan - I agree on both suggestions. I just recently learned that iron core inductors are suppose to be better than air core for the bass driver due to the lower dc resistance in many cases. Tannoy is one that uses iron core on some speakers,... | |
| AAA vs DDD... I have a vinyl copy of Zappa's Joe's Garage, DDA. It's excellent. | |

| testing a crossover imhififan - That is an excellent catch. I was beginning to think along with rodman, that maybe the problem was outside of the speaker crossovers. I think you may have nailed it. I suppose the single short could have caused both channels of the amp... | |
| testing a crossover imhififan - That was very helpful, thank you! | |
| testing a crossover **likklegerry - Small difference between the original capacitor values and the ones you installed will not cause failures of the amplifiers. If anything, it would have a SLIGHT chance to damage the tweeter or midrange driver. Since it appears that... | |
| testing a crossover Here are my posts from that day: 06-16-2021 5:40pmOkay, its been a rough couple days. I just got done drawing the schematic and looking at the words and measurements again. Just one note, do all measurement in the resistance mode, not in the diod... | |
| testing a crossover rodman - Just FYI, I did explain that the diode function test was to verify the charging and discharging of the capacitors. This was in my post of 6-16 @ 7:06pm. His answer showed there was no longer a short at the inputs of the mid/hi amp connect... | |
| testing a crossover I'm curious, do you have a list of parts that were replaced when the amp was serviced? A list from the first repair and one from the second repair might shed some light on a potential cause for the failures. | |
| testing a crossover I don't believe there is a problem that exists on the crossover any longer. Let's just do a few more tests. | |
| testing a crossover The fact that the speakers and amps worked of a couple or more hours is a hint that the problem may not be in the crossover. Are you SURE that when you bi-amped the speakers after getting the amp back from servicing that you didn't forget to remov... | |
| testing a crossover I didn't know you were in Bulgaria, that explains the delays in communication. I think a few more tests are the only thing that is required to conclude that the issue is solved. I'm still willing to try. | |
| testing a crossover The testing of the mid/hi input terminals showed the caps at that end of the circuit were charging and discharging. No shorts or problems were noted in that particular test. | |
| testing a crossover In one photo I can read 3.9uf/250V. When you drew and label the components on the circuit board the 4.2uf should have been 3.9? | |
| testing a crossover Stop, I would not strip any parts off either board. The data, answers to my questions, looked promising. You’ve already done a lot of visual inspection and testing. The most recent pictures, the cap with the blue circle around it, what is that? Su... |
