HI Wiljj78, is there a schematic for the regulator?

[Luke]

thanks

I'm planning to build the regulator. I'm wondering about transistor substitutions. Can I use MJE5032/33 for the BD241/242 and MJL21193/93 for the large ones?

Also, how critical is the 2k2 for the trimmer? Can I use 2k?

Thanks, Terry

I like this amplifier with positiv feedback !

 

[thimios]

Which is the maximum input voltage for this regulator?
Is it possible to use 2x100v transformer?

I like this amplifier with positiv feedback !

Feedback is negative

Yes but you need 160V caps...

that´s what i saw and thought too,but than Mile told me about common emiter connection...

today my SR150 got it´s inclosure,it is not homeless anymore

back side : input connectors mounted higher,output connectors are down side and LED signalizing "0K condition" on dc-overload protect...

this is a kind of music i prefer listen on this amplifier, https://www.youtube.com/watch?v=hy1dXeBbppk it really sounds better on SR150 than on most other amplifiers,so rich bass...

I built Sr200 Couple of years ago, and have been happily enjoying it till recently.
Now I am looking forward to rebuild this amp with latest version.

Would it be possible to integrate a preamp inside along with the amp. A tube stage or may be any good dac chip. This way it will be a complete amp .

And my single sided board version. PCB design is by TDA! He has several versions of single sided pcb and he is very competent and talented pcb designer.

Tnx.

@wiljj78 can you post Sprint file for PSU?
Tnx!

Hi wiljj78
please send me sprint file for psu
i will add some component ( led vs.)
