Does anyone know anyhitng about this? Not too much info it seems.

It's a nice unit, does need some work, Loudness knob is backwards, turning it down makes it louder, and all controls crackle when used. Good cleaning needed.

It has no power stickers on how much WPC, I'm just wondering how much it does put out?


Also, the unique half moon tuning thing, its definitely different. Interesting to say the least.

Based on power consumption on the rear label, I'd guess around 20WPC.

Cool as all get out, though! The loudness weirdness is a puzzler, though.

I have the DA-R10, it's a neat little receiver and I like having it in the collection. Mine is 40wpc, and the tuner section is very nice, pulls in stations better than most anything I have. I like having the adjustable loudness, although I usually keep it at highest level.

38 watts @8ohms (0.01% distortion) and 50 watts @4ohms. Search for DA-R8 and a site called analogalley.com pops up in the images tab with the cover of the service manual. The specs are there, albeit a little blurry. On the R10 some of the controls are hard to get to for cleaning and it uses power modules, not transistors for output, but has a heatsink that takes up the whole side so it is well "sunk". Only piece of equipment that I have that has wattage (a sticker on the cabinet) is a Technics receiver. The wattage on the back usually refers to the AC outlets, no the audio output. I don't know how many 30-50 watt amps I have seen posted as being 200 or 300 watt outputs!

My sansui, and my jvc both have a wattage sticker on the back. Guess certain models had different things (obviously)

Thanks for the info though

I do really like it, but the backwards messed up loudness control is a bit annoying.

Does anyone know why it would do this?

Its and input attenuator rather than a volume potentiometer.
The higher the number - the more the attenuation. The more attenuation - the lower in sound output.

Here's that spec sheet, 45 watts per according to the top line. I have the DA-R10:

The idea with that style of loudness control is to set the volume at the highest level that you are likely to listen to, with the loudness flat (at 0). You then use the loudness to adjust the volume down from there when listening at lower levels (late at night for example). Yamaha also uses the variable loudness control. It's a better way to go IMHO

Picked this up recently, TOTL DA-R35 receiver, and it's now cranking out tunes on my patio/porch system. I never gave enough credit to this early 80's Mitsu gear having always owned/collected the TOTL DA gear from the 70's. This receiver is a beast, and sounds great powering my Niles Audio OS outdoor speakers. :music:

I take it from reading the back labels, that each pair of speakers should be 4 ohm or higher? And with both channels running the impedence of each speaker should also be 4 ohm of higher? I think that's what I'm getting, not really sure
