Wow! He was very dedicated to go to such lengths, really interesting thread, thanks for sharing! :)
Thanks for your reply but there's a few reasons why I listen to tapes more than CD's. It's mostly because I use a Walkman with earphones, a...
Thanks for the reply Hugo, I'm going to try it out on the worst one. I've currently only got a Sony D6C to make the recording but the recordings...
I have a small collection of mainly 1980's pre-recorded tapes from my childhood but almost all sound disappointingly poor, to the point that I...
Great news to hear you got it working. You'll be very attached to that device now you've invested so much time and effort into it! The good thing...
I don't think you wired the diodes correctly. The anode connections look ok but the cathodes (with black stripe) should all be joined together and...
Or four 1N4148 diodes with their cathodes joined together. :nwink: you could even solder one in place just to see if the button starts working
That's a good idea Silver965, maybe attach with thin wires or enamelled copper wire to protect the solder pads from lifting.
Hope it fits. Will take some patience and steady hands to fit. I usually use leaded solder and a bit of flux to help the solder flow nicely. Good...
I think I know the function of the diodes in this circuit. When the Remote switch [S6] is set to OFF, Q13 is turned on and this pulls the cathodes...
[ATTACH] Diodes Incorporated MMBD4448HCQW is a 5-pin surface mount quad diode array with common cathode. Not sure if it would be small enough...
Thank you. I got that for a very reasonable £100 but it needed a new servo IC, new belts and tyres and a thorough service. I use it for all my...
Oh and that website is definitely dodgy! Photos and descriptions look like they're taken from an auction site and most seem to be discounted to £33
You could do a diode check between the pins to see if they conduct about 0.6V in one direction and open circuit in the opposite direction. I had a...
I haven't worked on this model but I did find this online;...

Just a quick photo of my modest personal stereo collection. Both Aiwa's owned since new, Sony's were bought with faults and needed various repairs...
It's a MDR-EX21E
Ah, so does the remote switch disable the buttons on the device? That would make sense!
Are there any through-vias on that missing pad? From the photo it looks like there might be some. Sometimes the vias are only there for mechanical...
