Don Sachs Owners Thread


A place to discuss amps, preamps, and phono stages from Don Sachs. 

 

I just purchased a like new D2 linestage. It has 2 gain controls, 64 step volume control, and digital volume readout. It is set up for the new rectifier. This is my first 6sn7 based linestage. It came with Ken-Rad Vt 231and gray RCA tubes. There are 3 rectifier tubes. A huge Philco 6BY5G, a Tung-Sol 6BY5G, and a Bendix 5852. There is also an Ice Age Audio power cord. With 2 different sounding outputs there are a lot of options. I need to find out what value the output caps are. I have the D2 connected at the moment to a VTL ST150. Input impedance is 125K and 2v in for maximum gain. 

I placed the RCA tubes in left front and rear and Ken-Rad in the right. Used Philco rectifier. Plugged VTL amp into output 1. The brightest sounding preamp I've ever heard. It was comical, bass drums sounded more like cymbals. Output 2 sounds like normal music. This surprises me. With 125K input, I thought there would be no problem getting bass response. 

Some questions.

1. Are the 6Sn7's in the right locations? I guessed by looking at the sellers photograph.

2. Is the Ice Age Audio the AC cord the brand Don offers as an option? 

3. I'll audition all 3 but which rectifier would be considered tops?

The linestage sounds amazing.

@lous  good to know. After the 2nd set of Linlai finish breaking in, I will compare them to my other tubes.

Anyone know the power draw of the D Sachs preamp? Considering a power regenerator. 

Thanks,

It uses a one amp slow blow or 2 amp fast blow. Does not pull much.  FYI, the most I ever measured a total system draw at full tilt Class A amps as well for ALL components was under 5 amps. SOmetimes components make a large draw on turn-on, but once running you would be surprised how little current you are running.

 

 

Thanks @mogelsvs ​​​​​@bugredmachine . Glad to know it doesn't draw much. Still undecided about the power regenerator. I have my own power transformer, out on the pole. But, things inside the house can also cause problems. The PS Audio is on sale this month. 

Thanks,
