I just got a 1594B. I'm new and I search for some info, what year they were made, what are the way to make the connection, what's the differance betwen the 2 transformer, and any other info you could give me!

I think the 159x series were the first solid state Altec amps. I have the A's, but haven't used them for anything.
One transformer is for the power supply, the other for the output.

1590 = 200W
1594 = 100W
1593 = 50W
The "A" model was strange in that it used a positive ground power supply.
All of these power amplifiers were patterned after the tube amps with a multiple-tap output transformers. The 1594B offers output taps of 4 ohms, 8 ohms, 16 ohms, 25V and 70V. The input is routed through an octal socket for either a 15335A or 15095A transformer.
15335A = 15k input
15095A = 600 input with 14dB of gain (used for the end of long wire runs)

If you go here and scroll down the amp section there is a 1594C manual
Altec Lansing Professional Audio - Vintage Speakers
Connections in and out should be the same.
The reason for patterning after the tube amps was to make them direct replacements to a huge installed base, and installers did not have to be re-trained...the service business was a substantial part of Altec's income...
Your neighbors called. They like your music.
I want to add a comment about sound quality;
The 1593B and 1594B sound great!

I heard something about using 1588 preamp in the socket for the input transformer. Is it possible?
