Hi Mika, Unfortunately, I don't have the Circuit Diagram, so I can't see its function. On this CD4 PCB (C8005015), it is D106. The Anode is connected to one of the Thumbwheel variable potentiometers (R122), and the Cathode is connected to the Blue wire (pin 4) on the 9-pin round INPUT to this CD4 PCB. See picture. This then goes up to the smaller

Hi BeoAus, Would you mind sharing with us how this white wheel melted? All it has on it is a low-tension rubber belt!!!! At first thought, I'd be looking inside Chinese toys with motors, to see if they have similar parts. Also, broken CD-ROM drives from computers - most of them have a drive mechanism which uses a similar belt-wheel setup - ask your

Hi All, Problem almost solved! The following 3 semiconductors were defective: Transistor NPN BC182B - replaced Transistor NPN MPSA13 - replaced The 3rd part, Germanium diode AA143, is a challenge. This is NLA at any reasonable price. Oh, of course, there are a few vendors willing to sell at outrageous MOQ's, or have a minimum order value of $250

Hi Mika, Thanks! This was a compound fault! Yes, first the arm didn't recognize the LP, and then later it recognized the LP, but didn't lower. It appears that it was a bad solder joint. On the Control PCB (the large Rectangular one on the left), I resoldered all the joints with wires on them. Everything MECHANICAL seems to be working OK now

Tried that! Didn't work. From At Rest position, I pressed Slow Move <. No response. I can't remember ever pressing < to start playing an LP, so I don't know if that is ever supposed to work from At Rest? Then I pressed START <<. The arm moved to the cue position, and stopped (as it should), but the arm didn't lower. I Pressed

Hi Peter Does that mean that I should stop the arm while it is moving? Seems a little violent! The press the Up/Down button (the middle one)? Menahem.

Hi all, My BG6000 Quad Type 5505 has a problem. It has operated flawlessly since I upgraded all the capacitors a couple of months ago. Now, pressing START, the arm moves to the left, ignores the LP on the platter, reaches the centre position, and returns right to the At-rest position again, at a speed of 45. The exact behaviour as if there is no LP

I've tended to not believe a thing the seller says about the mechanical condition of the equipment, and just accept that it will need work. IMHO, buying a unit in GOOD cosmetic condition, and unknown or poor mechanical condition, will usually get you the best deal. There is enough expertise on this site which can either repair, or help you to repair

Hi all, In an effort to try to lower the cost of our restorations, I have opened an account with Wima here in Israel. I have found out that it is possible to purchase these excellent capacitors at a very reasonable price, examples following. As you can see, the prices are way, way below those offered by Conrad.de, or Digikey.com. I am passing these

Hi Martin, You mention that the Philips Capacitors are hard to find. Philips was taken over by BC Components, and BC was bought by Vishay. You can still buy the Philips capacitors here - now called Vishay BC Series 138AML http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=4226PHCT-ND Digikey ships worldwide for a very low postage cost
