RE: Homemade Variovac

I don't know about the 70, but the Mark III's have a problem where the B+ exceeds the PS capacitor voltage ratings until the outputs warm up enough to conduct. The fix is a thermistor. If you search Dynaco inrush current limiter you will find a lot about this, including the 70.
