Hi folks

I would really appreciate some help with one of my Nakamichi 480z tape decks. It has developed a horrible popping noise in the left channel during record only. This occurs on all bias types, but playback is unaffected.

I have heard it is polyester capacitors and I am thinking maybe around the bias oscillator. I would love some opinions and I would also love a schematic........

Hope to hear from someone, soon!!!!!!!
