And how PCB capacitance spoiled the fist version… As you might have read, I am working on designing and building a tape head tube amplifier. For this you need quite some overall gain to overcome the gain losses in the equalization filter. Like at least 200.000; reason to split it up in 3 stages….
As mentioned in the earlier PR99 blog, I wanted to design and build a universal tape head amplifier. Just for fun and to see what I could squeeze out of the magnetic source, avoiding the internal Revox electronics. Which sounds great, but honestly I still do not get it as it is full with…

I use this one for the simple work, experimenting with electronics and playing the wonderful old pre recorded tapes from the…
