The is no azimuth adjustment on the 4ZM mechanism. Shiny/glazed pinch rollers are the most common issue for tape skew problems, try replacing...
Generally for SMD electrolytic capacitors in Walkmans, voltage is not really an issue as size is the limiting factor. Any modern cap that will fit...
Worst I've seen is a WM-F15 I found in a flea market for $3. It was dropped in the sea by a previous owner and was very badly corroded. Only the...
Bad solenoid-check resistance out of circuit. Bad play button- check hold switch, Play switch.
If you look at the schematic, Play/Stop is S9 and S10, top right hand side. They are connected to the hold switch S7, which may need replacement....
Use the service manual if available. If not, use a microscope/magnifying glass and trace manually. Bridge any corroded (blackened) traces by...
To clean the old tact switch, disassemble it and polish the contacts with a fibreglass pen, and coat with deoxit.
Converting through hole to SMD (and vice versa) is something I do often. The external battery cap replacement is optional. The tact switch might...
Don't reuse caps from other machines, chances are they are equally as bad. Buy new caps and do it properly. Jump broken traces with thin wire...
Belt replacement is easy on this model, but if the single pinch roller between the 2 heads is bad/dented, it's not worth doing, unless you can...
I don't have a gear with me at the moment to measure, but check if the clutch drive gear is touching the surrounding gears in FF/REW mode. There...
For future reference, I've also replied to this thread on Tapeheads as odgcwrtw: http://www.tapeheads.net/showthread.php?t=75753 Try using a...
That gear is probably too tall and preventing the other gears from meshing with the top of the clutch drive gear. If this is the case, it might be...
My recommendation for people new to recapping Walkmans is to buy a few similar, less valuable models and learn to do it there. Use a quality...
Your Aiwa is screaming/bad sound/distortion because the old electrolytic capacitors are bad, and need to be replaced. It has nothing to do with...
Thanks for the inspiration! The Aiwas are fine with 2.4-3.0v.
It's very easy to replace the caps in this model. On one of my copies the old caps were going out, on the other it was still ok, but I did it anyway.
I bought my DD9 in that condition as well. clean off the old rubber properly and you'll be fine. You may need to sand the surface of the new...
That means the unit is unable to properly reset logic state due to mechanical issues. Other than belts the capstan tires go soft and stop proper...
I'd recommend getting a smart charger. Far more convenient and fast. I use the Sony BC-9HA. You can also solder a gumstick holder to a modern...
