Hi all.
I have question about my Teach 3340. I'm recording with Ampex 456. The type with the backcoating on the non record side. The problem i'm having is that after a few passes through the tape heads I seem to lose all signal strength to channels 3 and 4. There doesn't appear to be any shedding going on as far as i can see with my eyes. and channels 1 and 2 record at the same strength.
If I then clean the heads it appears that channels 3 and 4 come back, but not for as long as i would like before they die down again. any advice?
thanks
james

I have demagnetized the heads. This did not amend the problem.
After demagnetizing, I applied a test tone to channels 3 and 4 and recorded. Monitoring of the record head the VU meter started at 0 and when the counter on the tape deck reached 30 the signal strength began to gradually decline until it was but a mere haze.
At that point, i created some slack in the tape and cleaned the heads with the tape at the same location. I did not notice anything coming off onto the q-tips (nor did i at the original cleaning). i then started the machine up again and was once again able to register some signal but it died off again and much more rapidly than it had at first.
Any ideas?
