Requires repair Ortofon DSS 601. Need help!

[alexsation]

Hello dear trolls !!
I have a sad story, 2 months ago bought in ebey cutting head Ortofon DSS601. The seller ensured that everything is in order, cutting head is in working order. When I got a stereo head, I immediately checked the resistance coils it was all in order, I calmed down and prepared the the whole system to connect this head. A few days ago I was able to connect the head and test the functionality of. I cut PVC, both channels are working, but the left channel produces wheezing and crackling, it is very audible, grates on the ear. One gets the impression that the coil touches a magnet and publish wheeze and crackles. Overloading is absent, are the fuses 100 mA. I can tell you that it is not the equipment, namely the cutting head provides a distortion. Please give advice, someone can be renovate, may be at whom that had a similar problem?
The sound floating, not dwell on this account, this test mode, wheezing very well heard.

Hmm, not 100% sure if it is the cutting head or mechanical problem.
Does the signal from feedback distort? Listen FB Monitor!
How do you insert your stylus? Do you have an original Ortofon Stylus?
You don't have a rubber over the moving parts of the cutterhead, maybe there is some dust/dirt or chip inside?
Does it distort at low volume? what frequency?
Test with sapphire and dubplate, maybe it is a problem with your diamond/pvc setup?
The suction tube, damping, spring etc. are mounted on a second carriage which gets moved by the main (old soviet) lathe? Maybe there is a problem...

As said many things can make problems in this setup...

I did some tests, Flo says it is 100% broken aluminum membrane!
I still attempt to do some experimenting, but I suppose it's useless
The equipment is in order, I was changing channels with each other, the result the same. disconnected a chip tube, it is possible to hear the head produces a sound inside wheezing

Hi, I listened to it your recording, you can hear distortion in both channels, you have made the measurement resistance of both coil? I wonder suspension of the head, and the counterweight sprung from behind. Is this a steel rod connected to a spring, the same rod touches to the copper tubes on both sides? This rod which moves the guide tube leads from chip? I have the impression that the turntable platter is running slightly out evenly vertically, thus slightly raises head up and as a result of the knife once harder, deeper falls in the master plate, and once shallower, record platter raises the knife to the head.You tested the phenomenon? Did you check? Regards

Hello sakuszi!
I has renovated cutting head and has solved all problems with the vacuum tube. Soon I will provide a video about the work done !!!

Great! We are pleased to watch! You wrote about knives with sapphire, ruby, if any progress grinding to size? If you do spike to 3 microns and an angle of 80 to 90 degrees, triangle, then buy a few pieces, I saw your auction on ebay, they are very cheap these knives, but I need more acute within 2 - 3 micron.

I already sharpened several pieces, it is not difficult, but has not yet tested them. In the coming days I will make shank with cone, and try stones. These stones were made long ago they have sharpening of 15 microns, it is done for that would did not break the tip of, unlike diamond, they are very brittle. I plan to cut the pressed disc PVC, stones should not break, it has a width of 15 microns, unlike diamond 2-3. If I get a good result, it's likely I will stop selling them.
