a cheap receiver for my first setup

[Roboturner91]

Finally I decided to experience the old stuff and the troubles /diy that might go with it
I found a Technics SU-V78, rated 100w/ch for cheap.
I know it's not top quality, but that ok since I don't want to risk messing with an expansive one.

Does anyone have the service manual for the SU-V78? I didn't find it

You did good, IMO. Technics stuff gets a bad rap sometimes because it looks a little chintzy but I've had only good experience with Technics gear.

That Technics is actually a pretty decent little amp. I used one for a bit with a pair of Dayton B652's and a small sub- surprisingly good!

Thanks, although I'd prefer a shared pdf than paying 30$ for some sheets

If you come across something NAD, I've never been disappointed in their sound. I bought an AVR for $100 and a receiver for $80. Both sound beautiful.

Do a search for that manual online. There are many sites that you can download manuals for free!

Thanks I've already been on this site but there is only the user manual, not service

Thanks but this isn't my unit, this one is actually older and has not the same output

Hey guys my SU-V78 has a weird behavior;


My left speaker is louder than the right, and the lower the volume is, the worse the difference is between the two.


It doesn't seem to be a balance issue, has when I switch from one another the it just confirms what I explained before; the right speaker doesn't get to the same loudness as the right.


It seems like something is off in my volume control, because my weak speaker went better after I played a bit with the volume knob


Have anyone seen this before? What would you do?

I've already done a pot cleaning a week ago (but no lubricant).

Thanks!

Sometimes they need to be cleaned again. Deoxit and work the control through its full range 30 to 50 times or more while the deoxit is still wet. Same for balance, volume, tone and any muting switches
