Got a bit of a problem with my new to me Tape deck (cassette).
There is a quite audible high frequency whine, from the unit itself, not through the speakers, that goes up and down in frequency as you turn the pitch control knob up and down.
This happens even when the unit is just switched on, with nothing at all plugged in. When you seitch it off the sound decays slowly in both volume and frequency.
Sounds like the motor, as many decks have motors that run all the time as soon as they’re powered up. When you switch off, the motor spins down and stops.
Could be a belt on its way out, or the motor needs a bit of lubricant.
The pitch control is effectively the motor speed controller, so adjusting the pitch makes the motor run faster or slower according to what you’re doing with the pitch control. (apologies for the man-splaining Mike, I’m sure you know this anyway).
I’m putting a cassette deck in for a service tomorrow shall I ask the guy his opinion for you?
The official service agent for Nakamichi is Bowers and Wilkins. They do a great job but they are spendy, a good indie can do the work a lot cheaper.
Btw, cheers for the razor, used it today. I’m not at all surprised you had trouble with it, it’s very, very “efficient”
No injuries to amuse the forum with though.
