Motor speed is independent of Ve of Q601 and Vcc of CX20084 as long as they're above certain thresholds. So yes MCP1702 + 1N5818 will work fine....
1N5818 will have a forward voltage drop of ~0.2V@150mA, meaning a power dissipation of 37.5mW. Also with NiMH cells 4.8V-0.2V = 4.6V. With the...
Note most of the current flows through the drive transistor Q601 (2SB1063), not through the IC itself. If we assume a current gain of 100 (which...
Belt routing is fine, that's how it should be. And they are turning in opposite directions, the idler reverses the direction. Look at the...
That piece of fabric is a felt pad, part of the clutch. On these series, the clutch is integrated into the takeup reel. To be noted takeup and...
That small white gear connected to the white rod is the detection lever. That's most likely the area where your problem is. The clutch looks...
But there is, you have the following websites which have huge databases with walkmans, recorders, decks: https://walkman.land/...
I think that's a very good idea. After all, if you're interested to find out more info about your units, you should create threads dedicated to...
In regard to the Japanese seller: apart from price, there's another problem: he doesn't seem to re-list many of such items. So it's possible he's...
1. For lubricating alone, you need to remove the back cover and tilt the PCB on the D6/D6C. On TCM-600, TPS-L2, WM-3 you need to remove the small...
Not aware of replacements being available at this point in time. Only solution are junk donor units. But it will become a common problem in the...
Given the FF and REW buttons do lock, you are more than likely looking at a worn latch. Seen this before. Unfortunately it's something that does...
Autoreverse on this mechanism is fully mechanical. What I would check is the clutch assembly (the big black gear). Carefully remove it by...
Ok, 0.04V - 0.14V is really nothing compared to the 2.5V-3V required. What about these 2 points indicated in picture attached ? If you get...
Don't quite understand what you mean by "center reads mostly positive", it can read either positive or negative. Also please let us know what do...
Hello and welcome to the forum @leamspaceman ! If Dolby is never to be used or only B is to be used, then indeed a D6 might be the better option....
Thanks for the info ! HS-PL55/555 has the Alpha-2 mech, there are pictures with it on the linked thread. Edited the first post adding all these...
It's best to measure with a multimeter before plugging in any AC adaptor. Even safer is to simply use AA rechargables (you will need the low...
A capacitor failure is very unlikely, only situation that can cause such symptom is when a capacitor that's across the voltage rail (C309 for...
Created this thread as I need some help in creating a list with all AIWA walkmans using the Alpha-2 mechanism....
