What are your requirements and preferences?

viki_v2 · 25th January 2011, 06:06 PM

frankly i do not posses much knowledge about these things, So any help is welcome.
The amp i am building is 500 watts amp.
i have heard solid state things, and now want to feel the musicality of tubes.
some help on what to look for will help me in deciding.

Well-designed tube preamps don't have musicality, but are simply transparent.

I would ike to feel what ransparent is like.
Tubes tend to give smooth and warm sound isnt it.

SY's Red Light District. Best pre I've ever built.

Over the weekend, I built a VERY simple pre-amp using a minimal number of components. To my ears, it's very transparent. At the moment I'm feeding it into a cheap Samson reference amplifier powering a pair of MS 816 speakers and it knocks spots off the old Technics hi fi amp that used to sit in my living room.

Most of the components can be soldered direct to the valve bases, and I used a piece of Veroboard for the power supply.

I'll second the triode connected EF86 preamp - I used a white cathode follower on the end of mine. Very nice sounding with budget or tricky-dicky parts.

The Borbelly was easy to clone and uses readilly available ECC83 and ECC81 valves
