Tube preamp.
 
Has anyone used tube preamps in their dj set-up?

Did you insert the preamp in to the send return or from the output of the mixer?

i've inserted a tube distortion pedal in the fx loop --
i wouldn't recommend it for DJing... much better for guitar

if you want a tube preamp/DJ mixer, why not bridge two vintage, class A, mono units?

you can normally find old preamps pretty cheap -- and the earlier/simple ones normally are pretty light on components requiring maint./updating
the biggest problem i run into is that the multi section can capacitors may not be available -- but discrete units can be fit in without too much trouble, normally -
sometimes it is a bit tight to get them to fit under the chassis.... if you want to maintain the cosmetics -- sometimes you can just clip the leads of the old can caps and leave them in place
when you fit the new caps in under the chassis top deck...

I found a pair of Harmon Kardon DPR-7 mixer preamps to do the job for me -at some point -- I still need to get to the project... ;)

but they were very reasonable, as most folks (excluding some "musical" types) are not into mono production/playback gear anymore...



(just don't go off and destroy a collectable/desirable instrument in the process -- please.)

A Valve Preamplifier offers too much output voltage for a send/return insert. It is safer for novice users to send the mixer's line outs directly to the input of valve preamplifier then, the output of the valve preamplifier to the input of the power amplifier.
