APEX You have started pcb for 200 series and have done more than half,have You finished it? If You have finished it,would You share that design with us? Greetings!
With +/-110V rail I suggest 12 pairs of outputs (it's class AB), and you need add bridge circuit on separate pcb with balanced inputs and low-cut filter...
It's pcb for SR400 not SR200, and it's for my comercial amps not for share.
For DIY SR200 you can use pcb design made by 'alex mm'.
Regards
Hi Mr. Mile Sir,
I have an existing bridge adapter circuit already and i'm using it with my other amplifier. It has a balance input configuration too.
Thank you once again for your assistance.

This pcb design by 'alex mm' not tested, but look OK, you can try it and come here if there was some problem.
Regards
My mistake-You´re right,sorry. These days I will compare schematics with alex mm` s pcb design. Greetings!

How would you implement dual FETs, like LSK389, on the LTP?
It might be interesting o try it.
Recommendation SR100?
Hi Apexaudio,
If I have one 2x60 750VA trafo. Would you recommend a regulated PSU with 2 pairs of end-T's and would it be OK to have 2 pairs of end-T's in the SR ... making it something near SR100?
I want to build a stereo amp for HiFi use.

LTP in Stidio Reference Amp use PNP transistors, for next amp I will use topology with N-FETs in LTP.
:
Amp will be like 'Ultimate Fidelity' with DC servo, and cascode instead super baxandal pair in VAS... I don't want made another 'Goldmund' clone🙂

I've seen several designs that use baxandall pair in VAS, much before Goldmund's, like Luxman, etc. I think you should keep that, because it does work very well and should have a good part in the amp's sound.
