WOW!!!! YES!!!!!!!!! I'm too jacked up.

ZM— Couldn't be more happy. Gave this a good listen today with family too who say "they don't have opinions"—right—they DO!) ... —A/B vinyl on two decks (HOLY SH&$ SP-10MKII). Some random family movies—Hi-res digital via Tidal and an R2R DAC—Opera (Mozart at the Met free on the interwebs due to Covid).

Learned a TON. It's warm and lovely—but not overly so—FULL—RICH—DETAILED—LAYERED—PUNCH—audio descriptions are so subjective. This is with AJ—already on the meaty side—I like meaty. Will try with F5 and report back. A/B with Wayne's—which I also love but has a different character. SO FUN. EVERYONE NEEDS TO BUILD BOTH.

This is a total WINNER—Hats off bowing. Soft mute is pretty trick. I didn't know what to expect. Pretty cool really. Works great—love having a remote. Tried 12 DB jumpers... think I prefer the 6 setting. AMP is quiet.

You can see the vision with the Wayne's stack, visually—just playing around.

NOW BACK TO LISTENING!

(I will build the balanced version. Getting there.....)

SE or Bal, whatever, lets talk about Rout per phase

Iron Pre - that would be Rout of buffer, multiplied with square of voltage ratio of output autoformer

Rout of complementary Toshiba JFet buffer is in range of 30R; when you choose 6db autoformer arrangement that's multiplied with 4 , so effective Rout is 120R; when you choose 12db arrangement , that's multiplied with 16, so effective Rout is 480R .....

Iron Pumpkin, having Iron on output which is serving same as attenuator and gain device ( autoformer) if chosen ;

lets set it for 0db gain , then highest effective Rout is on top tap (0db) and it's equal to Rout of my funny JFet buffer , which is having Rout in range of 20-25R ; every lower tap is resulting in dividing that with square of voltage ratio , so when you set volume to -6db , effective Rout is 25/4=6R25 , for -12db it is 25/16=1R5something


when you set AVC jumpers to, say, 6db gain , then you have highest Rout in top tap (6db) where you have JFet Rout multiplied with 4 , so that is 25*4=100R, while each lower volume step is having appropriately decreased effective Rout by same calculus

of course , everything explained applicable ditto for SE (Rca) and just double it for balanced

hope I was clear enough .....

"like" is an understatement ZM... it's a new world here. But I can't give you all the credit —SP-10 is quite a magician. All current combos are excellent for now. Couldn't stop the records this am... So good.

SP10 is Sissy



( I wish that I still have SL1400 .... great when tweaked)

Totally sissy. That’s why I’m restoring another one.
