Need preamp recommendations for a Dynakit ST-35.

I ended up buying an Erhard Aretha preamp.  :)

Have you looked into the  Transcendent Sound      
Vacuum Tube OTL Audio Amp Kits

The Slider

A True Innovation In Tube Technology
Variable Gain Preamp with Phono Stage
Zero Feedback Design

The ability to match the gain of the preamp to a tube amplifier will provide an improved overall sound.

Looks interesting and the price is right for sure.

Thanks for the replies. I have a friend with the Cary which he’s not using so it’s an option. 
 

Who makes the SP1 preamp kit?

jmolsberg, who makes that style preamp?  I’ll look out for one. 

why not build an SP1# kit to match?

that said where did you find a Cary SLP94 that's a killer preamp for the era (no remote though). i used to have one and still miss it. they are rare as well.

better than the offerings from Tubes4hifi IMO. I have Tubes4hifi MK4 mono's (ST-70 in 2 chassis) they are little bit noisy on my 105db horns couldn't use them unfortunately. 

I have the 3xrs HO and love them! If that amp has plenty of gain I would go with an autoformer passive pre. 

I am a very happy owner of a preamp and amplifier from Aric Audio. I reccomend you check Aric out online then if interested give Aric a call. You will benefit from the experience whether you go with one of his products or not.
