Thanks for help.
I have another question . During playback from tape in record mode or playback mode there are some low frequency noises on right channel. These is reason why I'll wish to try to swap reproduce card. Do you have any experience with this?
Hi,
I need help.
I have Revox B77 2 track. I bought reproduce amplifier card 1.177.250-13 to recap it and then replace old in my RTR. Inside is card 1.177.250-12 and it is different. Does somebody know which is difference between them and are they interchangeble.
