Tandberg 62X out of phase stereo?

    As a collector of Tandberg tape recorders - I have over 20 - I have been stumped by a recent repair I did.

    I replaced the grid capacitors, namely the .022uF and .047uF capacitors on the playback and record boards only (since they are valve based) because the original Rifas tend to leak. I didn't do anything else. The unit works fine... both L and R record perfectly but when played together in stereo the sound is out of phase. Reverse a speaker wire and it sounds fine.

    The are no obvious errors - none of the head or input wires have been mixed up. It looks as though one of the capacitors is doing it but I've never heard of such a thing. Could it be the cross field bias? A faulty valve - although they were replaced with new?

    The fault is on the record board - playback of prerecords is fine.

    Any ideas you fine people?

    Wow, 20 Tandbergs and JUST joined AK. I wonder what is going to happen to you now. (lol)

    Regarding your deck, since you checked cables, I am also stumped on what might be causing this, however should leave it to the valve to think about it.

    Hi,
    I was not previously in AudioKarma, but I saw your post
    in a search for Tandberg 62X, (I have one and it needs restoration).
    I didn't see that your problem had been resolved. Was it?
    Thanks in advance,
    Charlie Falke

    P.S. Which other Tandbergs have you got?
