Audio Specifications Database

We are compiling a database of audio equipment specifications gleaned from our annual equipment directory magazines, owner's manuals, service manuals, etc.

Audio Picture Gallery

Pictures of some of the equipment we've worked on, with occasional commentary.

Our Testing Procedures

We test the audio components we restore to ensure they perform at least as well as expected. This is both an overview of our measuring procedures, and an attempt to make clear exactly what is being measured.

SAE 2600 Gallery

Some pictures of an SAE 2600 power amp we restored. This amp has serious muscle; you can check out it's specs here.

The amp sounded great (it's audiophile calibre), and seemed to sound even better after it warmed up (or was it the speakers that warmed up?).

I hate to nitpick, but I will anyway. The power meters were very slow. They were accurate when the amp was driven with a steady test signal, but substantially under-reported the power output when playing music. Fortunately, the SAE 2600 has selectable meter sensitivity (the four push-buttons at the lower middle of the faceplate). Selecting the -6 dB setting (or even the -12 dB setting) provided more realistic results.

If you have an SAE 2600 amplifier that is in need of repair, call us at (519)513-1084, or email your enquiry to repairs@dnaelectronics.ca.

For more information about SAE products and the history of SAE, I recommend the following websites:

The SAE 2600 is powered by a very large EI power transformer. The picture doesn't really do it any justice.

The SAE 2600 has four power supply filter capacitors (9800 uF each), which could lead you to believe it has independent power supplies for both the left and right channels; it doesn't. The positive and negative supplies are each filtered by two capacitors in parallel, for 19600 uF per phase, or a total of 39200 uF.

This amp was equipped with 1/4" input jacks. The picture shows the phono-to-1/4" adapters we used to test the amp. The power cord shown here is not original.

Especially in the mid 1970's, SAE (Scientific Audio Electronics) manufactured superb audio components- power amplifiers in particular- that still resonate with audiophiles today.

The picture is a little bit fuzzy, but the last graduation on the meter is, in fact, 800 (!).
