First,hi folks!
I wasn't able to find an answer to my question,so here is my first post.

I am building a small audio system which is pretty complicated.In short,it is a small recording system which includes a behringer 10 imputs mixer,a mic,a computer with a nice creative soundcard,and logitech surround speakers set.
All this is wired together so i can control the volume on the mixer and listen to it on the speakers or record on the PC.The main out of the mixer will be wired to an eq and then the eq out will be connected(splitted too) to the PC and the speakers.No problem here.

I also want to wire a vintage cassette deck,a vintage CD changer.
I want to be able to change the volume from the deck out and the cd out with the mixer.I will also split the main out from the eq to the tape in to be able to record.
Note that I already purchased all the material,including the deck and cd changer.When I say vintage,its from 1970 to 2000.

This is where the complication starts.How to wire it to the mixer?
So far I was thinking about 3 things:
1-I wire it directly to the mixer using RCA outs.I would then be able to control volume independently on the mixer,but it will take 2 imputs instead of one and no possibility to get radio.
2-I buy a new mini hi-fi chain,and use the auxiliary imputs to connect the Cd changer.I would then unplug the speakers included with the system,and use a small speaker wire to rca adapter and wire it to the mixer.I would get radio.
3-I get a vintage receiver and wire the changer and tape to it,then run the tape out output to the mixer.I'll get fm radio.

I was planning to use #2.I already purchased a sony mini hi-fi system,after I started thinking if I did the right choice.I got a second chance offer on ebay on a receiver I had tried to get,and that made me think I should go with #3.

Few other questions:
What is inside this mini hi-fi?Can I get good sound from it?I was not able to find out since all the reviews use the included speaker pair,but what if I use it with my mixer instead?How does it perform vs a vintage stereo receiver?

I already purchased the sony hi-fi,but it would not be a problem to get the receiver instead.I could always use the sony stereo elsewhere.

Most was purchased on ebay,new.Some were used.I got good prices for almost every pieces.Prices include shipping.
Sorry for the long post,thanks in advance for your advice!
