I want to pick up a vintage SS integrated


Hi, as a stop gap solution, as well as for enjoyment, I wanna pick up a 70's vintage integrated amp.  I have been looking at the Kenwood KA 5700 as well as the KA 405.  Aside from the specs, which one was the higher end model, do you guys know?

My budget is around $500, and I like VU meters.  Around this range, what else could I be looking at?

Oh for sure I can pick up a modern one. I am in the market for a high end SS integrated, but as a stop gap I want to try a vintage, because of the aesthetics, plus they were also of a high quality. Real engineers were building real amplifiers, not "audiophile" gear for a wealthy set of clients.

As someone said Sansui did use glue on the boards but I think he has over stated the issues. Sansui integrated's are going up fast in the vintage market for a reason if you can get one like the 717 i'd jump on it they are only going up in price. Also Luxman, Accuphase older stuff are some of the best made form that era worth looking as well. but may be to late to get for under $500. 
That's the thing, I don't wanna go the route of Accuphase, Luxman or Marantz's sought after models which will cost maybe $1000 - $2000 in nice shape, which will defeat the point of this exercise :)

If I can find a recapped, nice looking integrated (50 WPC or more) for around $500, that'd be ideal. 

I am actually planning to buy something along the lines of the Luxman L509X sometime next year for regular use.
