I found this nice late '70s Akai tape deck in the e waste while looking for stuff for Disassembly Academy and it was too nice to trash without trying to fix it first. It looks like I revived it!

It looks like these were made from 1977-1978 and retailed for $200, the equivalent of $1,000 today

Well, it's not totally fixed. The auto-stop feature sometimes triggers randomly even when the tape hasn't reached its end. I'll have to see if I can figure out why
This mechanism is responsible for the auto-stop function. I don't really understand how it works, but I think the belt that runs across the top of the detection wheel is a little on the loose side, which may be what's causing this
This diagram would actually make a kind of cool tattoo
It goes pretty well with my Kenwood stereo. I don't know if I am going to keep it yet, but it does complement things

@MLE_online God I love the look of 70's Kenwood. I should really take the time to get my old Audio Reflex up and running again.

If you've never heard of Audio Reflex, my understanding is not a lot of poeple outside of Canada have. They got absorbed by a much larger Korean company in the early 80's I believe.

@MLE_online They need to bring back silver- face hifi gear. For a time it was so unwanted that even pawn shops around here wouldn't buy it.

@48kRAM @MLE_online 70's and early 80's was the golden period for Hifi. The machines are beautiful 😍

@Archie8 @48kRAM @MLE_online Figure you all will probably appreciate this then:
@acsawdey @48kRAM @MLE_online That's a beauty isn't it! With dbx as well 🤩
@Archie8 @48kRAM @MLE_online wondered if anyone would notice that little magic button .. it was a revelation at the time! Too bad I never had a car or portable with it, so pretty much limited to mix tapes.
@acsawdey @48kRAM @MLE_online
I like the electro mechanical nature of old tape decks. In many ways they're like clocks. The tension in the belts, the friction on the rollers. Everything is finely balanced

@MLE_online
It would certainly be niche

Where & how do you find the diagram for a 1977 tape deck?

@billheywood you just the name + the model + service manual and hope there's a website that has it
@MLE_online
It always amazes me what people have thought to digitise and keep online
@MLE_online the sensor for tension might be getting the wrong reading, have a faulty cable, or if there is a tuning threshold it could be reset…
@juandesant Thanks!
@MLE_online couple more things that came to mind: there might be a buildup of grease in the motor that sometimes creates more tension… or it might only be happening with certain tapes that might have been wound too tightly.
@MLE_online From what I can see and remember, my dad and one of my brothers each had one of those. They were expensive but nice!
@MLE_online Akai generally made good stuff.
@MLE_online I had one in the 80s. A double tape deck, I believe.
@MLE_online I bought that same AKAI tape deck model in 1980.
@MLE_online bought back happy memories of taking my tape deck apart in the eighties to fix it.
