Hello! I am new to this forum... looking for preamp design

[Javajiven]

I am new to this forum, but not to DIY audio projects.

I want to build a preamp module (for a solid state power amp)with (at the very least) Bass, Treble, volume, and pan/bal controls. I have seen some neat designs who's designer will sell PCB's for building it... but the cost for just the PCB + international shipping makes it VERY expensive. If anyone has a schematic and or PCB layout for something like this that they don't mind sharing, I would be very happy! Or if you know of a PCB I can buy from a US supplier (intl shipping more that doubles the cost), let me know please.

I recently completed building a P03 amp (http://sound.westhost.com/project03.htm), with a few additions (bypass caps mostly). I hand wired it, no PCB... wow hard work, but it paid off, it works GREAT! Very clean and articulate... my brother says its very punchy with no distortion (even when he had his fingers in his ears). I noted the depth of the bass first, then I began to notice a clarity of sound that was startling. Listening to music I have heared many times, I was astounded at what I had been missing while playing it from my TEAC receiver. Sometimes I was startled by a new sound that I did not expect... like the snare drums being hit by those metal bristled brushes... sounds like that are now distingushable... not lost in some grey sea of mass produced mediocrity. I also noticed that I can hear the noise in the recording itself... wow. The amp is cleaner than the source recording!

I am also planning to build a Quasi comp amp design to relace the guts in an old Kenwood Quad that smoked itself a while back... I am planning to use the power transformer, heatsinks, and chassis... This time I drafted a PCB based on the quasi-comp design from a schematic found on www.blackwidowaudio.com ... I made a few minor changes... but it is still the same basic design... I guess it can be found under Projects, 60 watt. If anyone has built this 60 Watt quasi-comp amp, let me know how it sounds and what mods you might have made.

Also, if you have a decent preamp design (you care to share) with bass, treb, vol and pan, post it here. Thanks!

Welcome to the forum. You haven't stated that you want your pre-amplifier to be solid state, so perhaps you might consider valves? The reason I suggest this is that valve circuits can be hardwired - so you don't need a PCB...

And valves provide a nice warm, cheery glow, most useful for those long, cold Alaska winter nights.
