Does the volume level vary (even a tiny bit) on R channel with different settings of the potentiometer ?
Do keep in mind the dot on the PCB silkscreen is the + not the - side on AIWAs. Not familiar with this particular model, but another thing to note...
Sound on R is faint and low only at full setting, but fine otherwise ? If so would measure the potentiometer resistance during a full rotation....
I presume the walkman does work only with a remote based on your description. If that is the case, it means IC701 is working fine and problem is...
Yes, it's normal to slightly change (a couple of mV) nothing to adjust there. Varies, some are close to the spec (315-320mV), some are way off...
AIWA HS-PX10/PX101/PX20 These units share the Z-1 mechanism. Many people say these only need a belt swap because there are no leaky capacitors,...
Want to update this thread in regard to the solution. The no sound or intermittent sound is caused by corrosion on a flex cable underneath the...
Yes, the 47k load resistors are one for each channel. Depending on specific test setup it can be just one in parallel with meter input since only...
@Dauner There's nothing signficantly different on the WM-D3 as far as replacing the center gear. Only thing extra you need to remove in the REC...
I think AIWA considers just the part of the frequency response that is flat (+/-0dB), hence why the apparently poor spec. In the attached picture...
A cracked clutch retainer won't cause speed issues, only decreased takeup torque. The 100mA current draw is with cassette in or without ? Manual...
Springs (part no. 333) have the following dimensions: OD (outer diameter) - 1.5mm WD (wire diameter) - 0.1mm L (total) - 5.5mm Closest I could...
Springs you will find on Aliexpress, but you need the dimensions (length, diameter, wire diameter). Will try to update later on regarding the...
In regard to the hold switch, you can add a blob of solder on the 2 upper terminals to short them together. Can also check the resistance of the...
That "Silent Mechanism" is likely a marketing gimmick, as mechanisms on these are mostly identical with very minor differences across the RQ-S...
"This might be because the vias are corroded/dirty?" - yes and ideally you should find where the problem is and fix with wire. Pressing the PCB...
Could be defective tape, it would be interesting to test it in another device being it a deck, walkman, boombox etc. and see if you can reproduce...
Given the radio works fine on both channels (assuming this based on info provided) and fact radio output is fed into the Dolby amp, we can...
Tape chewing is likely caused by some slight misalignment in your deck, don't see how the tape itself can cause chewing. Seen many situations...
DeckTech is a reputable belts seller. Buy confidently from them, belts will fit. Set I linked is for this exact model, not for a similar one. What...
