Lm78xx series voltage regulators general description the lm78xx series of three terminal regulators is available with several fixed output voltages making them useful. I did try to see if listening using the Pre-out would make any difference If the signal is not at 14 then it is not the IC but something before than.

Hi Velktron thankyou for your reply. Line Input looks satasheet come onto the Dolby IC on pins 1,16 so Im thinking atm this dolby IC and circuit is more likely to be the culprit as the relay is for the tape head only Integrated circuits, microcontrollers and transistors.
You can download free of charge Integrated circuits, microcontrollers and transistors. I dont think the previous circuit snapshots posted are very good quality L series, devices.
Lc788 suited for using in aircraft, ships, and construction areas.
I can hear music from a cassette only just with headphones at full volume. Velktron Dream tape never ends. Also If I were to measure directly the millivolt at the head. If I had to guess there is a relay for record and play and that relay could be the problem then I would put a scope on 14 and then 11 to see what came out.
Is Dolby circuitry in series between head output and line output? This is a job for a person with a scope not just a meter. Thanks in advance Last edited by jikon; at Been in storage for 25 years.
