Buying an item in this condition was always risky. But the seller did not say that the problem was only in the mechanics. At this point, it is...
Intermediate tuning results for both modes. MID mode: [ATTACH] MAX mode: [ATTACH] It's not finished yet. The maximum bass boost level is...
Thank you, @givemeyourwalkmans. You've summed up all the best thoughts about the Walkman ever made. Unfortunately, these days, they are...
Throughout the years of Walkman production, they have produced best models and cost-cutting models. Around now, what you see on the market is...
I noticed that in this case, the factory specs of the NJM2106 microchip completely coincided with the actual measurements in the device. It's good...
Thank you for your interest in my research. The next step is to reduce the bass boost and limit the frequency range of the boost. You're right...
All these malfunctions are caused by increased or decreased resistance between the buttons, which are then incorrectly interpreted by the...
Probably oxidation of the button or switch board. These are all connected together into an array of resistors, which are later measured by the...
Here are the frequency response measurements of the original circuit in 'MAX' EX-DBB mode. All measurements refer to one channel (left) since both...
Here are the frequency response measurements of the original circuit in 'MID' EX-DBB mode. All measurements refer to one channel (left) since both...
Here are the frequency response measurements of the original circuit in 'Normal' EX-DBB mode. Left channel: [ATTACH] Right channel: [ATTACH] L+R...
Thank you, Valentin. I thought so too. I'll take a chance and buy a couple more belts from DeckTech to see if there are any differences.
I decided to do the electronic tuning first and then do the mechanical tuning. The PCB is in the access path to the gear drive for maintenance, so...
Thank you, Duane. I am getting ~0.5% RMS with new drive belt and pinch rollers from fixyouaudio. So far I've only cleaned everything on the tape...
Okay, today I found time to unsolder the coupling capacitors C112, C212 from the input side of the NJM2106M chip for both stereo channels....
Yeah, try turning it quickly by hand while applying voltage. One way or the other. Measure the resistance of the motor leads by slowly turning...
I'm a big fan of some bands of the past whose music had a long monotonous sound. Ace of Base - Happy Nation is one of them Now that I have a...
What is it? MOLYKOTE Em 30 L?
Sounds like a very fun life! I am an electronics engineer with a specialty in Radio Electronics. So all kinds of laboratory equipment...
Thank you! This is a really deep cleaning points. I'm talking about the capstan bearings (brass bushings?) and the pinch roller axles. I was...
