Tascam 38 Purchased new by me in 1983. Original and only owner. I got my 38 out of mothballs about two years ago and set my home studio back up to finish some songs put on hold when life got in the way. Installed new belt and new rubber pinch roller. All worked fine until about 6 weeks ago. Issues: 1. When using the sync head, channel 1 does not work. The channel 1 VU meter shows no activity and there is no output. 2. When using the repro head, channel 7 does not work. The channel 7 VU meter shows no activity and there is no output. I checked the tape and there is information on both channels 1 and 7. I keep the heads meticulously clean (since it is old tape it will tend to shed) and have demaged also. I’ve done a lot of reading here and many have talked about the sound cards, relays and caps. I’ve found sound cards on the web for the 38 for around $30. Should I get a couple, replace 1 & 7 and try that approach? Help!! Thanks!
