It really depends, mostly on the condition of the device. It is to be kept in mind a new rubber set for these devices is not available at this...
Seems good at first glance. On input and output, use tantalum/low ESR electrolytics instead of ceramic. You can add the recommended 100nF...
You need some headroom in both current handling (especially cause you won't have any heatsink) and dropout. Output current should be 500mA at...
I have a solution, if you're really concerned with the inconsistent tape speed: add a linear voltage regulator between the battery terminals and...
Ok, thanks for the detailed description of voltage --> speed correlation, that is what I was looking for. I'd say given the realtive simplicity...
First of all you should use a 3kHz test signal for adjusting/measuring tape speed, not a 440Hz (440Hz is used for level calibration). Note the...
No, I did not. No picture with that lever unfortunately.
