This monday, Daniil (danila_95) visited Ufa. Except for walking around the city and other fun stuff, he also brought this not-quite-little goodness that Alex Nak got me here.
The [B] well was not working, however, which was quite disappointing with such a powerful machine.
So it was time to jump right into the schematics of it. After some hours of probing and reading, it seemed that QM61 and QM62 were out of business after some weird occasion. The reel motor was spinning, yet no motion was seen from the capstans and the head mechanics (which are, in fact, driven by the same motor). So I had to go to the local electronics shop and get two 2SD2144’s (I was lucky enough to come on time because these were the last two in stock).
Replacing these was a bit hard since the mechanical assembly is in the way of removing the main board. But, after reassembling was done, I connected it to a 110V AC adapter, put in a tape, hit play… Sure enough they both work fine, in reverse and direct modes!
Time to hook it up into the rig, well A to the amp as a usual recorder, and well B to a USB sound interface (a 24-bit USB Sound Blaster) for instant recording, broadcasting and digitization purposes.
Now gotta think up a better stand for the audio equipment, a way of making this work with AIEdit2, and how to get the pillow that was inside back to Alex 🙂
Enjoying the Haibane Renmei cassette on it as I’m typing this post~
