Hey Folks, I am new here. This is my first post. I have built many amps repaired restored at lest twenty st70's, an sca35, and a couple pass2/3 preamps.
Anyway, I found this a few weeks ago and bout this so I thought I would share.
None of this is mine, I am not affiliated in any way with the seller or the items. This is all on evilbay.
I am waiting on the tube sockets and then I can do final assembly. I'll post some pics and impressions then.
I tried to post the links, but oops, I am just too new.
The users name is Ifnickel search for him and you will see a very nice chassis and the associated card to build that version of the st35.
THis is a cut and paste from his listing
"Hello Tube Lovers,
Hello Tube lovers I just received a new lot of PCBS. I have here the bare board for sale of ST-35 Dynaco Replica New Design!!!!!
The board is similar as the old Shannon Parks Audio SCA-35 design Rev C, and D, that is obsolete.
The PCB was tested 100%, and we have amplifiers built with it sold. We've sold boards to NY, NJ, CA, MI, MN, FL, UK and we keep going! it's been a success!
We decided to start with bare PCB for sale, and we might put a kit together if we found interest.
It uses ½ 12AX7A and ½ a 12AU7 per channel. The 12AX7A is a low noise preamplifier that directly drives the cathodes phase splitter 12AU7. We also replaced a single cathode resistor and capacitor with four individual resistors and capacitors. The original cathode bias resistor has been replaced with individual feature that allows your ST-35 to perform to its full potential. The circuit incorporates 4 trim pots to set individual Bias per EL-84. Once adjusted with 0.35V, the amplifier is ready to operate. For best performance is recommended to have a well quad matched EL-84 tube on this project."
