Re: Nearly silent output from vantone reel to reel machine
Yes, I think there were lots of these styles of machines manufactured in Japan in the late 1960s under various brand names. I recognized the head arrangement and some other internal parts from a machine I once had labeled the 'Granada 207'. Fairly well built, but the DC bias system was a letdown as all recordings had that typical DC bias rumbling noise in the background. Given that there are 5 transistors in the amp circuit, it's a pity they didn't invest in the additional switching and HF coil needed to convert the output stage to a bias oscillator in record mode which would have improved matters significantly, even when retaining the permanent magnet erase head.
