I have been thinking, I have two dead cassette players. Dead because the transports don’t work. The Sony, I made worse looking at the belts, the Nak came from a friend who had the belts replaced, but never used it, or who knows, but seems to be missing a belt or two.
Anyway, my question has to do with linear power supplies. I have Raspberry Pi3 running off a wall wart. I was wondering if I could use one the power supplies in there, by adding some type of regulator, to take it to 5v+ and I would need to find the amperage.
With the Raspberry’s LPSs seem to be one of the things that make a big difference. Both Bryston and Audio Alchemy have players based on the Raspberry, that were selling for over $1k. I imagine they have proprietary firmware and good power supplies, well the Bryston, you never know with AA on the firmware. Any thoughts?
This may be beyond my abilities, I can solder, not as well as I used to, maybe just out of practice. Years ago, I built a couple of small simple kits, a voltage monitor, based on a LED display, and a little amp board. They both worked. This was a long time ago, I wanted to learn about electronics. But life got in the way, and I am back to basics, at best.
