Hey guys, been a long time! I recently acquired an M70 off eBay with a functional tape deck. But basically everything else doesn’t work. FM and AM radio produce no sound (not even static) I was able to find a very low volume short wave signal but that was it. Also the tuner dial seems all out of whack, you have to spin it a lot before it starts moving in a different direction and it has severely reduced range across the spectrum (will not travel down past 96)
When plugged into AC power or running on batteries the power light is constantly on, volume while running the tape deck is much lower when switched to the ‘ON’ position and volume spikes up when switched to the OFF position. The volume jumps around intermittently while in the off position but that’s the only way I can get any kind of substantial volume out of the unit.It’s still severely underpowered though and sounds like crap with barely any bass.
Volume, Bass and Treble sliders all do have a noticeable effect. VU meters right and left do respond to music. But when switched to ‘TUNE BATT’ the level barely gets past 20% when it should be all the way up when plugged into AC power.
Pressing the dial light button or program button will basically mute the music.
Ive taken the back cover off and sprayed the sliders with deoxit, as well as all input/output jacks and repeatedly plugged and unplugged them with an RCA and headphone jack (large and small).
The internals seems a little daunting to me to dig further.
What have I gotten myself into??
