Apt-Holman pre-amp

I have enjoyed all of the excellent feedback on the apt pre amp. I can agree with the utilitatian qualities of the apt and must also agree with the fact that it is obviously been outgunned by technology. I still think it is not a bad piece for $225.00 or so.

Still hard to beat for accuracy and neutrality. Phono stage still among the best. Tracking excellent. Distortion at limits of detectability, even after 35 years in service driving everything from Citation II to Macs to Parasound and many others that we have A-B'd in friends' homes.
Soundstage is excellent - the folks above who couldn't find the sound image must have been using the "expand" mode - 12:00 is stereo, 5:00 eliminates center channel, 7:00 is mono. That "Mode" knob is a great tool to "help" lousy recording engineering.
Superb shielding, one of the best at avoiding microphonics. Tone controls have defeat switch if you don't want them.
Doesn't have the "solid state" sound- it's a nice compliment to tube amps (auto mute on turn-on waits for your tubes to get going, too).
Pots and Mute button get noisy after time.

It was a great design in its day.  I had one, I bought it used when i was 16.  It was my first preamp and not a bad introduction to separates.  Then I replaced it  with a P.S. Audio 6.2 preamp which was a great preamp, and the first component I regretted selling.  I replaced it with a McIntosh C15 which was good , but I think I liked that PS better.  Don't get me wrong, the Apt was good but finding a nice one can be tough, and people ask too much for them in my opinion.  In hindsight I wish I still had the Holman because it is unique and super flexible.  I had the Apt 1 amp which I thought was pretty good also.  Another piece I wish I had kept.

Ironically the Apt had a very good phono stage, fairly adjustable.... so if you were looking for a classic pre with a good phono it might not be a bad choice.

17 years later....

a few years ago I used to upgrade the holman preamps.

They are old enough now that a full recap would be a good choice.
There are two short falls with the Holman pre amp.

1. a tiny power supply transformer
2. the TL072 texas instruments op amps.

Both can easily be corrected. Tons of choices out there now for dual op-amps. Same with transformers. I would normally leave the original in place and bring in the secondary wiring from the new transformer into the unit.
The apt pre also uses quite a few electrolytic caps to couple the stages together. These should all be bypassed with a film and foil cap.

And if you really want to go wild, you can Vishay the whole signal path resistors with the metal foil types.
