Vintage receivers???

 Consider also the Kenwood receivers from the 1970's. A friend of mine has a Kenwood receiver bought new in 1975. It has never needed service and still sounds great. 

The biggest problems with old Marantz receivers isn't the sound quality. It's the idiotic prices for the units and the time it takes to get work done on them. All that said, I discourage some models such as the 2270. That's a complicated receiver with complicated adjustments that are prone to drifting and it requires service every couple of years to keep it in spec. The mid and late 70's designs are less complicated. The 2230 is well regarded for it's tuner and phono section, often compared to the 2270, and it's simpler. 
Recapping them isn't hard. Some people make it more complicated than it is. It's not that hard. 

I have very fond memories of the mid70’s Sony STR 6065. Big, beefy, yet amazingly refined sound.

Astounding build quality—thick veneer over the chassis with a thick metal front panel. Beautifully damped witches and knobs, great little headphone output. A very conservative 65 WPC/8ohms. 

The only weak area the volume pot. Prone to collecting dirt and eventually crapping out. 

They're around...

Agree on the prices.........many of the better vintage receivers sell for as much or MORE now than they did new. I guess what was good, still is, and people will pay for it...............I don't mind that part, but I'd hate to drop good $$$ on a 30-40-50 year old unit and have to dump a bunch more into repairs and rehab.................Might be less aggravation and less expensive to go with something more recent :(

I'll keep looking, might find a prize!!

I really like my Marantz 2252B, works and sounds great. My biggest gripe is the speaker cable connection to the rear of the classic receivers, back in the day when we only used zip cord that was fine but times and technology have changed. I hate the thought of shipping it to someone to convert the speaker cable hook up to five-way binding posts.
