The Singing Bush

Finally my SIT Singing Bush mono are completed!
Thank you again, Nelson, Zen Mod, Mark Johnson(soft start PCB).

Thank you for replying to my # 606 post.
The speaker in the picture was just a cheap speaker for initial test.
I'm sorry to confuse you guys.

well, when one lives in Parts Mecca (Tokyo), all what's needed is perseverance ( hunting will) and money

🙂

see what's brewing - as I said the other day to my older brother - Uncle Bubba Bob - it'll be as usual - either all The Glory, or Major Flop :rofl:

trying to make ultimate biasing arrangement for SissySIT, to accommodate whatever Ugs of SIT is at hand

finally .......... having it sketched for more than 6-7-8 months, and always short either in time or energy; hope to try it finally these days, and it took me just few hours to make this Ikebana

anyway and anyhow - for heatsinks that nice, something must be made

last lhquam's efforts are interesting (SIT + puck mosfet), take a peek if you already didn't

Pa did use xformer in all mosfet iteration to introduce Schade feedback to lower mosfet, thus transforming it in triode like gain device

handy , so Greedy Boyz are able to make an amp with 20-30$ gain device, plus same costing xformer, having pretty close performance as part mostly unavailable

besides reading enclosed article, re-watching Papa's lecture could help you to understand it fully

so, we can still choose - to use available Toking elevator thingies and comply to lesser performance than with real deal nowhere to find, or to use approx same costing {mosfet+xformer} combo, still having lesser performance than with real deal nowhere to find, but with different flavor

🙂

Since I received my Singing Bush twice, yes Master ZenMod was extremely generous! Unfortunately, returning the kit would cost too much money so he asked me to donate the kit to someone wanting to build one. It is the A+B kit

Kit is FREE but only pay for shipping (North America only). Anyone wanting to add a little extra money, will be all donated to DIYaudio forum.

If you're interested please PM me.

Thanks ZenMod for being so generous ! :cheers:
