Thanks! It's Rustoleum Universal Metallic Oil-Rubbed Bronze. I got it at Ace Hardware, but I'm sure Home Depot or Lowe's has it too. If you can't find it, I can take a pic of the spray can - I think I still have it a around.

Check this guide here - should give you all the info you need to know, but agree with previous poster that some disassembly is almost always required: http://www.audiokarma.org/forums/showthread.php?t=207005

  Yes, most likely.  Try to DeOxit the volume pot as well as all other pots (tone controls, balance, etc), switches, selector controls, etc - exercise each control many times after you spray the contacts with DeOxit.     Also, make sure you allow some time for DeOxit to dry before you power...

I suspect the s is for signal and g is for ground, so you have a left signal and ground and right signal and ground. If that's the case, then L-js would go to the left red speaker out, L-eg would go to the left black speaker out, R-js to the right red speaker out, and R-eg to the right black...

Music playing after you shut it off isn't necessarily an issue - many vintage receivers do this. Have you tried to clean all the switches and selector knob contacts as well? The volume control is just one of typically many controls that might cause a channel to cut out. If the left channel can...

Got a new vintage receiver in, a Sony STR-6060F, had it fully recapped.   This late 60's Sony receiver has a reputation for being tube-like, so I compared it against both a fully recapped Marantz 1060 and a Fisher KX-100 tube integrated on Vandersteen 2CE Signatures.  Thought I'd post my note...

  Twin power H/K units (430, 730, 930) are really nice sounding.  I think the build quality is somewhat below some of the other brands (Sansui, Yamaha, Marantz, etc) of similar time period, but the sound itself is really nice.

The Sansui quads are nice. I had a QR-6500 and the build quality was great and the flexibility of use was awesome. Basically, two receivers in one chassis in terms of flexibilty. Not a ton of power, and cap coupled, so more mellow sounding, and BIG. But nice overall if you have the space and...

  Is there anything in particular you're looking to improve upon?  What speakers are you driving with the CA-800?   From my experience, the Yamahas are really nice units (heavy duty, high build quality) and very neutral.  If you just wanted a different flavor (more warmth/color, etc) that's...

I agree on the looks. To a point, I'll take a classy/sexy looking piece that is a step below a pedestrian or ugly piece that sounds somewhat better.

  Well, I'm not familiar with that model, but here are the considerations I would think about:   If it's original/unrestored, it will require servicing at some point since the caps are >35yrs old.  If you can do the work yourself and it's a reasonably easy unit to access boards to do the...

Right, most just have dropping resistors that cut the power down to something that gives you more travel on the volume knob without risking blowing your headphone drivers. I have a pair of HE-5LE's and have run them straight out of the speaker outputs (just using a four wire to XLR adapter). I...

  You really have to take a look at the operating condition and bring your headphones to demo them with the unit.  Because some of these old units may have a relatively higher noise floor than what you'd find with a modern headphone amp, and you need to see whether that's the case and if so...

  You never know.  I never thought I'd be majorly invested in vintage stuff either, but it can be a little addictive when you get a nice vintage piece that oozes quality and tactile goodness.  But it is smart to start slow and see how it appeals to you.  It's very good that you're good with a...

Really depends upon your budget, but you can start with less expensive units and see how it goes from there. Within the Marantz line, you can try a 2010 or 2015 - lower wattage, so many using speakers may want the higher powered units, but these should be fine for your HD650's. If you don't...
