Thanks to Tom and others for helping with the questions. First ST-35 is finished.
This one is a Rev B and is built into a recycled chassis, some hammond iron and parts I had lying around.
Fired right up, very quiet. Diddly hum on my ~100db sensitive sansui horns. This is a sweet amp and has a very enjoyable tube sound. This iteration has a nice midrange, not the last word in clarity but very nice. The bass is killer, taut, detailed and deep. Highs are extended and smooth. No rolled off extremes at either end.
Will be interesting to see how it compares to the other amp (better parts and Triode reissue iron). That one is 80% complete but I need a couple more bits and bobs for it before I can finish.
Tks to the designer and the board for a great amp and all the support.
BTW for anyone looking for an image to copy from, dont use this one. I flipped the tube around to the other side of the board and moved parts around to fit everything inside the chassis.
Cheers
