Don Sachs Phono Stage

I have just recently come across the Don Sachs Phono Stage, but haven't been able to find much technical information about it?

For those of you in the know....

What tube compliment does it use?

Does it use any FET's or is it an all tube design?

What is the gain in dB?

I am assuming it is strictly a moving magnet design.  I would be planning on using my Tango SUT with it.  Any issues with noise, hum, tube rush?

Thanks much for your help,
Wishing you all the best of health and happiness,
Don
