Default Re: Telefunken magnetophon C 2200 hifi Cassette Deck

Rechecked line recording using attenuated Phono to DIN cable (470kohm in each recording channel). Now get pretty good results on both channels.

Strange that the right channel has now come good because before with unattenuated cable, the right channel was very low/quiet, maybe had a bad connection somewhere.

On peak music getting around 0 on the VU meter at around record level 2.5 (6 being max setting). If record level taken above 2.5 there is a hint of distortion coming in when listening on headphones at the cassette deck.

Need to see what the line output to stereo amp sounds like, wondering if my 32 ohms headphones (400 ohms being the spec for the machine) are starting to overload on playback of stronger record levels. Depending upon results may try another cable with 1 Mohm resistor attenuation.

Not sure if the Stereo/Mono switch is working correctly, need to do more tests.
