Amber, anyone?


Remember Amber?  Tony Cordsman's  highly praising review made the Series 70 power amp very popular in the early Eighties, outgunning many of the earlier and big-name transistor amps of the period.  Although rated at only 70wpc it put out closer to 90w at 8ohms and rates at 200wpc at 8 ohms when used as a monoblock.  It featured two massive 32,000 mF capacitora as the centerpieces of its power supply.

I owned one at the time and sold it as a system along with Heil speakers and a Citation 11 preamp to my closests friends when I got the urge to try something, and it has been in constant use ever since and still sounds fantastic.  Recently as part of my downsizing I sold my five home theatre Outlaw monoblocks and needed something to fill in until I can figure out what to make the permanent power amps in my main and secondary stereo systems.  I happened to see an Amber for sale at an inexpensive price, so I took a chance.  At first I wasn't impressed .... didn't sound as good as my friend's amp.  Then I remembered the power supply capacitor, was fortunate enough to obtain a copy of the manual, and sure enough heeded the warning that the amp would take days to reform the capacitors, and should ideally always be left on.  After a week of breakin, the beast sounds just like my friends.  I was encouraged enough to take a chance on a second Amber (one of the later models with wooden end caps) for my other system.  After breakin, similar results.

These amps have the clarity of vintage Audio Research and Conrad Johnson amplifiers.  They have decent transparency (not great ... is there any vintage amp that does?).  They are bright, but have no edge.  Strings sound like strings, snare drum strikes like snare drum strikes, and cymbals like cymbals.  Bass, of course, is excellent.  And voices sound natural.  At least that is my take, and at least one of the amps will stay in my system driving Thiel 2 2's.  The other drives my 3.5's just fine, but may be replaced.

I am interested in what you'all might think of or have experienced with the amp.  And of course, if any of you are still using one, as I now am.

roberjerman .... well, you still have a couch available, don't you?  why do you have to sit down, anyway.  Standing is better for your health.:-)

mrdecibel .... like you, I dream of what an upgrade could do to these amps.  I may have a tech friend do a capacitor upgrade on one of my Ambers so I can listen side by side.  I agree that vintage gear needs upgrading .... the revolution in passive components during the 1980's makes a huge difference in transparency.  

All that said, these are still musically pleasant speakers, as is today.
Thanks mrdecibel .... you have it right.  And my old age is just making such mistakes more common, unfortunately.

Your advice is solid .... I will surely talk with my friend before undertaking anything more ambitious than the capacitors.
