Lazy Singing Bush

[MEPER]

I was thinking about using thermal glue between the two heat sinks but need the chassis to check how tight the two heat sinks sit together.

 

[Zen Mod]

not enough "meat" that way, to ensure proper heatspreading

been there, done that, remembered that I heard some saying about probability of getting free lunch

 

[MEPER]

We could ask Gianluca for double size heat sinks for "Lazy Bush".

 

[JeyDee]

Well, im thinking that it would be fun to build and have them both: The Singing Bush and the Lazy Singing Bush. Of what i have gatered so far they have different sonic characters. Could be fun🙂

How about the avaliability of them parts kits? Now, weeks away, months away?

Are we supposed to ”place orders” via PM, or how does this work???

🙃

 

[MEPER]

I think PM for PCBs. I did that. Then you are into the queue to be served. FIFO principle, I think.

Okey🙂

I have found a trade post:

https://www.diyaudio.com/community/threads/the-singing-bush-kits.350518/

But that one is ONLY for the NOT so lazy singing bush?🙃

Yea, i am the super newbie of the day 😎🙂🙂

 

[JeyDee]

What du you guys think, would this SMPS be forbidden heresy and a deadly sin in combination whith the Lazy Singing Bush? 🙂🙂🙂

Do you know any other really good SMPS alternatives?

I might be wrong, but this one seems really HQ:

Hypex SMPS1200A400 2 x 64 VDC 1200 Watt Switch Mode Power Supply

https://www.soundimports.eu/en/hype...MImuOOiJr--gIV049oCR3jlwD0EAQYASABEgJo6_D_BwE

Would the 64V be reasonable in both the lazy and the not so lazy singing SIT:s?

 

[Zen Mod]

if that rocks your Boat, why not?

it is OK, 64Vdc is perfect for rail

though, count on some HF garbage filter, post switcher PSU

edit: take care - you need single rail; didn't look at small details, but linked one looks as bipolar , meaning +/-64Vdc

 

[JeyDee]

Yea, thats right. Its Not 2x64V as written on the site, its +/-64. 😐

First channel of Lazy SB complete. Came up perfectly. Listening in mono - sounds great! Hope to measure a bit later, as well as finish second channel.

 

[JeyDee]

Beautiful. 🙂

 

[Zen Mod]

you made it with 2SK77B ...........

 

[codyt]

It was just too easy not to try it first

Got any extras?

 

[JeyDee]

This is a extremely good High End opportunity for me to make a solid point, that have been bugging me…

No man alive can trustworthy judge a final HiFi system by listening to a single speaker or a single channel (amplifier).

It is equivalent to licking one of the cold cast iron frying pans, and talk about the following and upcoming top notch multi course dinner.

🎷🙂🎸
Just sayin it, as it really is 👍

I do, but they have “THF-51” written on the side

believe it or not, I had few revelation moments, exactly that way

in few occasions I finished just one channel prototype and tried it mono, one amp channel to one speaker

though, used extra-familiar music (must!) and proper xformer stereo to mono summation

still remember collecting jaw from the floor, that much I was surprised with mono experience

 

[JeyDee]

Yea, Zen, you can surely get a pretty darn strong hint, by one channel, if you are a extremely seasoned and skilled speaker/amp building dude.

But you know what i mean 🙂

 

[codyt]

Alright, second channel completed. Sounding great! I started with the standard .2/.2 mu ratio, but will try a bit more resistance on MOS side at some point.
