I wandered around on Facebook; part of my old stereo system in 1976 was pictured.

This is the pre and power amp.



My cassette player.

oh, the memories.

oh, the memories.

Yeah... I remember my old Harman-Kardon cassette deck.  Superior sound quality for a cassette deck, imho.

HK used "constant current" instead of "constant voltage" to supply the signal to the recording head.

The result was that the bass recorded did not have the ups and downs in level that most (all?) other cassette decks exhibited.

At the time, I worked for a record company, so I took home some frequency response measuring equipment one evening.

Long story short, my HK cassette deck measured +/- 0.5dB from 15Hz to 21KHz.

Yes that was an actual measurement I made on my cassette deck.  I was so surprised, I measured it again.  And again.

(I was using Maxell cassettes, fwiw.  Though I no longer remember the exact tape used.)

 
But wow.

Constant current vs. constant voltage.

Who would have thought?

I looked at some of the big audio companies that were big at the time and I can't find any that made audio equipment like we had back then. I guess computers replaced them all.

My Speaker system for my Computer is 500 Watts. that's about all I can say about it.

I was really proud of that system when I had it.

my real to real was a Pioneer RT-707 Reel to Reel Tape Recorder, They have a few on eBay for like $1,400

My first HiFi purchase, back in the 1970s, was an Akai AA-1040.
My parents still have this receiver, and it still works.

I never had a tuner, but wanted one.

this was another component I had was an equalizer.
