Depends on the design of the unit. In Audio Research, Aesthetix and Allnic, three that I have experimented with, the effect is huge.
Tubes in the preamp's power supply -how important?
I have EL84 and EF86 tubes used in separated power supply module of the line/phono tube preamplifier.
Stock tubes are Sovtek EL84 and Electro-Harmonix EF86.
I am curious how important is the tubes quality in such application. Is there any reason to change tubes to some NOS – Telefunkens for example?
How important these tubes are in power supply?
If change – what tubes do you recommend?
