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. 

Thanks,

I did replace my rectifier resistor tonight. The previous one was, in fact, blown, and open. The new resistor is a 0.22 ohm.

It does not make noisy tubes quieter btw.

The D. Sachs D2 linestage sounds really great now that the 4 Linlai E 6SN7 tubes have broken in. It is large and imposing with such large tubes stacked on double socket savers. It takes up a lot more shelf room. The tubes seem to do everything darn well. My various old stock tubes might do 1 or 2 things better, but then really fall down in other areas. The Linlai are very even handed.

 

Bought a PS Audio S300 amp during their sale. It keeps the room a lot cooler than the 8 tube 6550 amp and Pioneer class A. Now it is a race between the linestage and Ayre Codex DAC for hottest component.

Don told me that the buffers were not critical. If you have plenty of money, use whatever, but if not you may want to use a less expensive tube as a buffer.

@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,
