TEAC 1/2" Open-Reel Schematic Needed
I have a Teac Model 80-8 1/2" open reel machine I have to repair for a
customer. This is the first 1/2", 8-track machine I've worked on and it's clear I'm going to need a schematic. The main problem is that some channels are sounding through to others; for example, with a signal connected to channel 1 only, it sounds over to channel 2 and faintly to channel 3. This happens even when monitoring the input without a tape loaded, ruling out a head alignment issue. Any advice, or especially a schematic, would be appreciated. |
