  1. that and the fact that linear model has a Sony KSS-213Q pickup and non-linear Philips VAM1202. Interestingly, the 4 chip unit is only single ended whereas this is balanced. The CS4396 DAC is used in other quality gear like Audio Research, McIntosh, Quad, Myriad, Hegel, Acoustic Arts, Jolida all of which are much more expensive.
  2. The display issue and the remote control issue I could probably deal with (for I fix CD players for living) but could you tell me if it is : Consonance Reference CD-2.2 / CS4396-KS / VAM1202 or Consonance Reference CD-2.2 Linear / 4 x TDA1543A / KSS-213Q For myself, I really would be interested in a 4 DAC solution. Cheers Roman
  3. and for a number of different reasons too. This is like saying, if the car's engine tries but does not start, the problem is ignition. It can be. But also could be lack of fuel. How about a microswitch that should tell the servo that the CD tray is in place and CD is loaded but does not because it is faulty or dirty?
  4. Indeed I do know a bit more for this is what I do for the last few years. Nor reading CDs or CD-Rs of some kind is almost never due to laser problem. I have replaced less than half-a-dozen of lasers in the last 3 years. The issue is almost always mechanical or electrical misalignment. Sony based players have 5+ pots on the main board to adjust things like focus and tracking gain/bias, EFM, etc. Philips based ones have none. So start with cleaning the laser lens with isopropyl alcohol. Then look if the lens hunts for focus -> close the tray with no CD in and observe if the head travels to the centre of CD (next to turntable) and then that the lens goes up and down couple of times trying to focus and that the laser lights up red (do not look into it, observe from the distance at an angle). Then check if everything travels well. Find gear that drives mechanism and see if you advance it slowly with your finger that it all goes smoothly. Do not grease things that have no grease. If in doubt, clean the old grease away and put none rather than wrong grease. The send me a message. Otherwise, If all this fails, send it to someone to do it for you. Half of my work is fixing things for people who were only to replace belts and in the process broke a microswitch or installed the tray gears/cams in wrong position. If you were to buy replacement mechanism, buy a whole thing, so it is easier for you to do it. Before placing an order, remove the old one, so that you know exactly which one to get. This includes cabling which differs between models. This goes for both ribbon cables as well as servo/power leads that have headers with different amount of pins. For original stuff, your easiest option is Wagner - if they still have it. Next best thing is to get a cheap working unit from cheaper brand than Mission/Curus that uses the same assembly.
  5. One could implement it as a mod by simply breaking into voltage supply line and bringing the switch to the back plane. Just a disconnection is not really a mod as such. As I said, I am happy to buy it anytime you wish to part with it Cheers Roman
  6. That's interesting. What was the purpose of that? I just looked at the diagram and indeed, it would be easy to do, because audio board is separate from the rest. But having only a decoder there, 2 x DAC7 chips, couple of OP-AMPs and a muting circuit, I am curious what was the thinking behind it.
  7. I would be interested and I could fix the analogue stage. It probably has been disconnected due to fault. Let me know if it is available.
  8. Volker, If you sell these, are you going to change your nick on SNA? GLWTS Roman
  9. It is an interface between a computer and audio gear. Most laptops these days do not come with digital outputs and this lets you interface one to audio gear. You will have more of those. If you haven't had any use for these outputs, you will have even more useless things. But if you are a musician who makes music on a laptop and you need to send signal to DACs, processors and the like, this is a thing for you. It probably is the best there is of this kind.
  10. To the point of ridiculous. The inverting/non-inverting signals in the XLR have entirely mirrored driver and output-stages tied to a floating common ground. Are the balanced stages differential (design wise)? If they are, maybe I should investigate Krell in depth and switch over from my beloved Electrocompaniet. 😊
  11. David, thanks for the write up. On the last photo of the insides, one can see a number of high power resistors with paint coming off them and a very dull looking fuse. Maybe this is an area to start looking for a problem and a reason why self-protection is activated. Certainly a good piece of kit and looks well engineered. I like the fact that it only has balanced and current driven inputs. This suggests it is a proper, balanced design.
  12. Thanks for the detailed story of the amp. What is actually wrong with it? What it does and does not do an is the fault always present or intermittent?
  13. Maybe Tony, maybe even me if I had more info on this. I do have a spare VAM-1254 mech (otherwise known as CDM-PRO 2) ex. Electrocompaniet EMC-1 UP, but there is more to it. It all depends on how much was removed. Just the mech or some CD player specific parts too (long chassis assembly) and also what is the electrical interface like. If I could examine it in details, then perhaps it would be a goer. pm sent with an offer
  14. Used to have one of these in the old country. Nice TT. Sadly, also have been told that one of these (but Electronic Reference) was dumped in a skip when a friend re-located over East and the end of his life. His kids just cleaned the house. Luckily, you saved it from similar fate. GLWTS
