Is an Apt preamp a good preamp for my setup.

So old its bound to be widely out of spec, if you do buy it , hook only to some speahers you can live without. Been there, done that.

The Holman pre was a ahead of it's time, regarding presentation(for a SS design). If you can get it for less than $200; this is a good place to get it updated: (http://www.angelfire.com/art2/stereorepair117/holman.htm)

I owned one and found it lifeless. Yes, ahead of its time in the 1980s, but much has changed since then. And perhaps, mine was out of spec. I would look elsewhere such as Audio Refinement or any other very decent preamps.

Did some more research on it and found the most common problem with the apt preamps are mute relay going bad and sometimes the power button going out. Do not know if the previous owner replaced or upgraded anything on this unit. Anyway to tell if its a generation 1 or gen 2 preamp? Have noticed that they are selling on ebay for 250 to 500 and there seems to be a demand for the 30 year old unit. Thanks for the link to APT/HOLMAN Repair Service, I also found Audioproz and the owner Vince Naeve worked for Apt as a tech. They do upgrades and service as well as selling nos parts for the apt preamps and amps. I was able to get a great price on the unit and the store said that they'd give me full refund if the unit had any issues. I hooked it up and have had it running since Friday at 6:30pm with two power breaks on Saturday at 3pm to 4pm and 6pm to 11pm. So far I've tested the unit with my cd connected to aux 1. Unit runs fine and the sound is pleasing and even across both channels. The switches and buttons all seem to work. If I open the unit up would there be tell tail signs as to if the previous owner replaced or upgraded anything. The store selling it had no idea on the subject.
