Preamp with tone control.

I second Rrogs recommendation for the Dyna PAS 3x. Get it retubed, recapped, and cleaned. You should be satisfied with the results Happy Listening,

Jim Bonjourno is making a line called Spread Spectrum Technologies. He has a preamp called Ambrosia... It has tone controls. I have not heard it, but have read maybe a 1/2 dozen reviews. The worst of the write ups say that it is outstanding and is truely a hybrid in sound between very good tube and very good transistor. I don't know your budgets, but this is worth looking at.
After I read all of this, I re read your post and saw the price range that you are looking at. I decided to leave the above, but recommend: No tone controls, but wonderful gear.
Musical Fidelity A3CR
Muse Model 3
Audio Research LS9
Coda Window Continuum 4
All very good and can be had @ $500.00 to $800.00 on the used market.

Has tone controls, plus if you find one that is an EC model that doesn't have tone controls, Frank will add them for you.

In the '80s, I bought a NAD1700 tuner/preamp.
Tone controls were really flexible. 60/125/250 bass and 3k/6k/12k treble.
select one of each.
Also, on the back panel was a 20hz rumble filter and a front panel 'loudness' which boosted bass and treble....both a little.
It had 2 sets of outputs and 2 tape loops......
The phone input was pretty good, too, and had selectable MM/ MC .

I kept it for over 20 years. Gave it away working fine. NOBODY would give me anything near the 75$ I was asking.

Apt Holman preamp has some very flexible tone controls and an excellent phono section, renown in fact. A clear step above Hafler.
