6V6 line preamp-progress2-jpgMade some progress.
Rectification is solid state followed by a single 6AX4. Not enough space for another 5v transformer. And I reckoned the 6X5 would be a little fragile.

Okay, you guys have motivated me to get mine in a case. Bas and Buzz, forgive me in advance as I am going to steal bits of your chassis design to make mine.

Here it is now, and has been for almost 6 mos. Since it is staying it is time to make it safe with a decent WAF. I will keep you posted. Looking forward to getting in the woodshop.

How much of the circuit's quality is depending on the stiffness of the power supply? I mean, is the active regulation (and fixed heater current) obligatory for good operation?

NB Bas, are you gluing in the transformers and capacitors?

Glue with silicon kit. And a screw or 2 to keep it in place while the silicon is drying.

The active regulation probably takes it to the next level. But I'm starting of my listening sessions without the regulators. But Salas's SSHV2 are almost finished. And I will try them after a month of so of listening to the regular psu.
