I have a Teac A-4070G and when I record in reverse, the left channel drops out. Even if I playback of tape that I know recorded properly in reverse, there is no playback on the left channel. Could that be capacitors in my amplifier? I haven’t taken it in yet because of this coronavirus junk going around. It records and playback forward perfectly, just in reverse there’s no left channel.
Most of these decks will use the same playback circuit for both forward and reverse, not all will. It could be a bad relay or a dirty switch. This Akai had a switch on the head assembly to choose what head it is using. A little spray of DeoxIT can fix a lot of things. I had a deck that was doing the same as yours. I found a relay at the output the flip the channels when in reverse. That turn out to be the problem. But then one never knows until they can look at it.
Excellent sir
Wow! Lots of capacitors and transistors on that puppy. Good job.
Thanks for showing. I gonna look at one for sale in the next few days and so I know how to operate it.
Good video, thanks!
Amazing job! I have the same Akai model but it has some problems. Are you by any chance in the East coast? Thanks!
