Changing Tubes


Looking to change the Electro Harmonix 6922 tubes in my Aesthetix Pallene preamp 

What would you replace them with

128x128tomstruck

Is there something you don't like about the EH? What sonic characteristics do you seek?

There are many great tubes in the 88 family but these four would be sonically my first choice.

Voskhods 6n23p 1975-1977 period (best bass, flow, effortless, extended, holographic), my best choice and the greatest value, fit and forget.

Siemens E188cc A frames 1970-1973 period (more detail than cca).

Reflektor 6n23p 1974-1975 period, most likely at the top of 88 family of tubes. Very expensive (the only one i do not own but have listened).

Amperex Holland ecc88 (Bugle boys) and e88cc D-getters 1958-1959 period.

The first three extremely quiet, very difficult to go microphonic, linear tubes and close to character compared with your EH but way much better. Reason for noting close to character is that your pre was created with such sounding tubes in mind.

Amperex are very transparent, extended and especially the ecc88 has great mids but can go microphonic.

 

 

 

 

More air and bigger soundstage if possible 

Change out EH 6SN7 out of my Atlas amp  with Tung-sol 6SN7GTBs

Haven't done any tube rolling was amazed at the change in the amp

more air and bigger soundstage

Mention what preamp you have, how many tubes you need, what sonic characteristics you’re looking for and your budget. 

I’ve gotten tubes from Brent in the past and he was always spot on with a recommendation. Good luck!
