space echo repair....no echo!

hi there..just wondering if there is an easy solution to this that I can do myself..my RE 301 was working fine, then chewed the tape..when I replaced the tape the delay signal was suddenly absent..what could cause this? could the heads have become magnetized? would that render them useless until demagnetized? thanks!

Easiest solution - perhaps the tape is reversed (wrong side towards the heads)?

Right.

ANd your heads would not magically magnetize in an instant. Magnetized heads lose high end recording response, they don't go dead. They just get sorta muffled.

well, i've tried a few different types of tape, and tried them on both sides, no sound..strange..just immediately stopped working.

Well, if it ain't the tape, it is something in the electronics. I'd look for loose wires, I'd touch the playback head wirs to see if hum comes out - checks the playback amp. I'd be looking for a lack of bias oscillator.

thanks enzo..the funny thing is, it IS playing some of the previously recorded stuff on the tape I just put on it..little scraps of sound are looping sparsely..it doesn't seem to be recording..

[Enzo]

That points right at the bias oscillator then. No bias - won't record.
