hey guys!
I have a DIY 6N8P GU-50 amplifier which i really like.
i didnt build this amp myself, but purchased it from a fellow Aussie that diy's.
I love this amp, and would really like to build an amp myself, ide like to build the same one infact, but use better qaulity components (my current one uses cheap chinese components that im slowly upgrading.
it seems to be a simple amp design.
Now what ide really really like to do is build a mono block version of it!
i understand that i would need two power supply/rectifier circuits.
But how complicated would it be to build a monoblock version of this,
two separate amps in separate chassis, one for each channel.
they will be used on FHXL alpair 10p speakers.
ive attached the schematic of the amplifier i have.
it is a common DIY project as far as i can see.
Ide like to get the total cost excluding tubes and chassis under $500 AUD.
would that be possible?
Kindest regards

Why not ask the bloke who built your amp what he would do and involve him in your project.
If you duplicated the power supply you will get a slight increase in B+ which you can model with PSUD. It probably won't make too much difference. Otherwise everything else can remain the same though you might be able to optimize the parts layout better in monoblocks. I suspect that if you use the same parts the sound of the monoblocks won't be too different from the combined version.
If it were me, I would continue doing what you are already doing by modify the existing amp. Change one part at a time to hear what the effect of the change would be. Think of it as a learning experience.
