Could tube rectifier make have impact on sound

In the Jadis,the EL84 appears to be part of the regulator circuit.

Hi!
Thanks for your response. I´m not familiar with DPMC in terms of design/diagram (which I don´t have).
To clarify, power supply (as far as I can see) is a combination of EL84 & EF86 (Svetlana screened for low noise). I also have a volume potentiometer on DPMC for regulating voltage on output.
So yes Hifitime, you seem to know about DPMC or how El84 works.
EL84/EF86 also have to act as a rectifer, cause I only have a bridge diod for rectifying 12 volt DC.
Finally, could sound improve by changing these tubes (or one of them).

Many thanks and have a nice audio weekend!

I have noticed changes in sound when rolling both rectifier and regulator tubes. My Supratek Chenin came with Sovtek 5AR4s, but now I have settled on a Mullard GZ33 as the best for my system. Also I have experimented wth dfferent regulator tubes (Sovtek "5881", NOS Tung-Sol 5881 and Sovtek KT-66) and have settled on the Sovtek KT-66. The combo of the GZ33 and KT-66 is just right for my tastes.

Hi Ait.
I just ordered an EL86-Telefunken NOS from sixties.
Tube is part of a regulating circuit.
Sovtek EL84 is original tube but 86 has higher voltage after regulating which can be an advantage apart from what Telefunken is known for soundwise.
Looking Forward!

Many Thanks!
