    Vantec Nexstar 3 power supply

    Hi all I have a perfect working Nexstar 3 HDD enclosure, but the power supply is bust. It is a funny thing with 5V and 12V outputs. Any ideas where I can get a replacement?

    Vintage amp, speakers and turntable.

    Here it is in action: http://youtu.be/aB7c-snUHH4. The camera doesn't do it justice, it sounds a lot better Please look at the schematic, page 13: http://www.oudio.nl/service/22rh790.pdf Th power supply circuit is the bottom right corner. Should I replace all the electrolytics, or just the...

    Vintage amp, speakers and turntable.

    When I opened the amp, I found that pin 5 on the DIN 5 socket is not connected to anything and pin 3 is wired directly to pin 4. So I moved the wire from pin 5 to pin 1, and whoala, stereo! :D

    Vintage amp, speakers and turntable.

    Ok, both measure ~1.1K Ohm, so I need to trouble shoot the amp. I suspect it is somewhere in the phone input stage. I have my TV connected to the tape deck input, and that works in stereo. Which caps will need replacement, the electrolytic caps or all of them? Is there some way to test a cap in...

    Vintage amp, speakers and turntable.

    Jip I have it connected to the RH790. I changed the selector, and now the levels are OK. I fine tuned the RPM's as well. Another thing, is the GP400 cartridge supposed to be stereo? I ask because the left channel is dead. I measured the connectivity all the way from the tonearm to the DIN plug...

    Vintage amp, speakers and turntable.

    I found the problem, both the start and stop buttons made contact (where in the closed position). I removed the PCB, turned it over and bent the contact levers down a bit. So it works! :D Two more things: The output level is very low, I have to turn the volume almost all the way up on the amp...

    Vintage amp, speakers and turntable.

    Thanks I've fixed everything that is obviously wrong, but it is not turning. The two bulbs light up when I switch it on. I place a record on the table, move the tonearm into position on the edge of the record, and I press start. But then noting happens. I lifted the platter and I see the motor...

    Vintage amp, speakers and turntable.

    Ok i got different size belts from Jico, a 5 pin DIN plug and a  new stylus. What is the wiring on the DIN plug? There are four wires: blue, red, white and yellow. And a screen/ground/return wire. I found this on Wikipedia http://en.wikipedia.org/wiki/DIN_connector, but it doesn't tie up with...

    Vintage amp, speakers and turntable.

    Any idea what size drive belt I need? The service manual only says "belt" http://www.oudio.nl/service/22ga202.pdf. This site mentions 14.3" http://www.turntablebelts.com/philips.htm. Is that even a standard size? The guy from Comptronics said they are out of stock of "size 125" belts

    Vintage amp, speakers and turntable.

    A couple of photos to illustrate the problem with the cartage and stylus One of the wires came loose, but I can solder it back on. The whole thing tends to "drop out" of the tone-arm, with only friction keeping it there. There seems to be some glue residue on it, but i'm unsure if that was...

    Thanks. I've been browsing the for sale section, and option 2 seems more viable now.

I went through them and most of them are pristine condition, but two or three are a bit dusty. Where can i buy a cleaning...
