Old and solid from the outside. Did you compare it to something serious?
Lots of knobs and switches: crackling noises and mediocre sound. But if you like it ...

there are a lot of fine sounding Pioneer, Sanyo, Kenwood amps . The Japanese do have an affinity for "fussiness" but many of the designs from this era still sound quite nice.

a classic British belt-drive -- the conniseur (sp?) BD-1 + Grace 707 in a DIY base.

I built this 20 years ago. sold it, it came back 15 years later & a good friend has it now.

Wow. That Pioneer looks mighty familiar. My first amp in college was a Pioneer that was obviously from the same family as that - doesn't look exactly the same - mine didn't have the reinforcing crossbar, and fewer switches on the front.

Like you, though, I was very surprised at how good it sounded. I was ready to replace it with an entry-level 'audiophile' integrated (Arcam maybe) and when I demo-ed them side by side the Pioneer held up very very well.

brings back good memories of back when I actually had lots of spare time to really listen to music......

Here's another thread dealing with classic gear:😉 http://www.diyaudio.com/forums/showthread.php?s=&threadid=4939&highlight=older+classic+looking+gear

Hey, I have worked on more than three of that exact pioneer amp.

I gutted one that someone fried to death, and repaired two others that were only slightly fried.

I thinkmy nicest classical piece of eqiupment is my Harman/Kardon
A402 amplifier.

It is one of the best sounding amplifiers I have heard and its front end beats that of some $5000.00 Marantz front ends. That's got something to say for it.

I'll have to post a picture of it if anybody wants to see!

Onkyo A7

This is an example (not working) of an Onkyo A7 which was one of the very best of the mainstream Japanese amps of the late 70s -- 65 w/channel. Better than the Pioneers, Sonys, Technics, Sansuis... it shot them all down (but didn't best an NAD 3020).

I'm not sure whether to take it in an see if it can be fixed for reasonable money or use it for the power supply, heat sinks, chassis, vol pot & selector switch -- but what to put in it that can take advantage of 42-0-42 DC rails?

Onkyo A7

and the inside.

BTW: this was the matching amp for the Onkyo T9 tuner.

thats one thing i like about the old classics thay never go cheap on the transformer or main caps😉


beefy hmmm

 

[jackinnj]

I had reliability problems with my NAD -- I also shot the output transistors on my Pioneer amp more than once, another Pioneer receiver which own has the best darn tuner I've ever used (not enough bread for a Sequerra).
