Very nice thread. I have build an amp before but I'm interested in downloading the software and doing this project as well.
Has anyone built the amp? I would like to see some photos and build one myself!
This will be a very nice little amp, a true classic piece of history.
Well done by Mr. Pass.

Default Indipendent power supply

Hi,
Before chopping the PCB Tazz made with no return back, I would like some help to go in the right direction.

Many thanks and Happy 2017

Vito

R2 and the Emitter of Q3 must be attached, or you will have trouble.

IMO, easier to simply RC filter then front end supply.

yup

obvious benefits if you intend to use it in last watt region

if you intend to use it in first watt (and normally above that) region , just put them all on same rails , with decent RC in between (as Papa said)

that show me a completely new perspective, I intended just sent cleanest power supply to the front end, but the FIRST WATT is the place to be !!!!
I've calculate the RC filter to not let drop the Voltage too much....
Thank you to take time to give a look if it's a good interpretation of your words!!!
