Hello to all, first post, great Forum!
I'm using a Linn Axis power supply in a remote enclosure to drive my LP12.
The Axis supply was a bit of a "stretcher case" when I first got it, but several BUX85's and op amps later, the supply is now running at both speeds.
The output transistors are getting pretty hot though, and I noticed that the reduction of the motor volts, once up to speed, isn't happening. I still have 76v (?) to both windings with no variation.
Anyone able to point me in the right direction?
This is a swine of a circuit to get going, but I'm so close to success now, maybe someone had already been here?
I have a copy of the circuit diagram.
Thanks in advance.
