Thanks for the tip @mattb1970 - I'll check it out! For the WM-D3 it's a 3V to 8.2V, but I'm sure there's something to glean from the DC2...
Hi there, I'm currently in the process of repairing a WM-D3 w/ no sound at either Line or Headphone amps, and have removed and opened the DC-DC...
Hi there, I’ve been on the lookout for a Nakamichi 550 in decent condition for a little while now. They seem to pop up on eBay and elsewhere...
Yikes! You must have really been quiet, motionless, and in the zone for that mouse to have hung around long enough to chew through a cable. So...
Oh - almost forgot! I'd noticed while going through the board v. schematics the resistor (?) that's circled in the pictures attached. My...
Thank you Jorge. Haven't gotten around to it this week, but hoping to dig back in this weekend. To test/improve my understanding, given that...
Thanks Jorge! I’ll be reviewing your post more thoroughly tomorrow, but in the meantime, can I ask about that current reading specifically? Is it...
Thanks Jorge. So what I did was solder a lead to each of the input power terminals of the AC adapter input, and placed my multimeter between the...
Awesome thread! Agreed that these portable recording decks are beautiful, and given the various mechanical designs over the years have so far been...
Thanks Jorge! For measuring the current draw, should I be placing one probe on a test point early in the circuit, and the other on a test point...
Also, your point about the solder points on the missing capacitors - one was solder free, one set of holes was actually fully covered over with...
Thanks Jorge! I’d suspected that diode as a good place to start for checking whether wrong adapter was used. Removed most of the solder w a...
Hi all, I picked up a Sony D-4 Discman "for repair", which I've thus far not been able to get to turn on w/ either a DIY battery pack or a 9V tip...
