Tube Pre-amp Suggestions.

Consider a used Allnic L-3000.  Excellent value for the price. Robust build and quality.

@biwire Van Alstine looks cool, but I would like to stick with a balanced set-up. The Allnic mentioned here is balanced but overbalanced for my checkbook at present!

I use Supratek preamp with my Coda S5.5.

It is a most amazing match! A match made in heaven as they say :)

@glenmschneider I took my preamp out of my system. The Pasithea preamp works marvelous. 

@kds space tech lab has many balanced preamps, some of his offerings use power tubes. You can call or email space tech and he will answer any questions you might have.
