Firstly just like to say hello, registered minutes ago and really the purpose is is to ask a question re a Decware amp.
I am UK based(Scotland) and wanted some information on a Decware 34i.3. I have the chance to buy one and I am aware you can swap the valves out for alternatives. The question I have is by doing this can you increase power output as my Dennis Had or does it just alter the sound?

I have emailed Decware but wondered if any one here would know?

Regards
Colin

Thanks Lon by appreciably could I get an extra couple of watts say by using 88’s but that’s about it. If so that’s ok

Thanks

Colin,

Without doubling the power of the amp it would be a tad difficult to hear a difference from an output perspective, given all others variables kept constant.  

I have an earlier version of this amp (SE34I.2+).  When I swapped the Siemens EL34’s with some KT77’s, I remember the bass got a little better and it sounded as if the volume was higher, but actually it was not, it was simply the different frequencies in the music that were brought out by the tubes in comparison to the previous set of tubes.

Best,

Alper
