Receivers with dual transformers.

I was on another thread about a Sanyo receiver, and how it has two power transformers in it, and it got me thinking about other receivers that are similarly equipped. Here are the ones that I can come up with (and probably own) off the top of my head. Not counting integrated amps or power amps.

Concept 16.5 165 wpc, 8ohms
Sanyo JCX 2900K 120 wpc, 8ohms
Onkyo TX 8500, 8500 Mk II 110 and 160 wpc, 8ohms
Harman/Kardon 430, 730 these are especially impressive considering that they are 30 and 45 wpc, respectively.

Are there any others?

I can't remember specifically if the Sansui G-33000 did, but considering the power supply was in its own 50lb. cabinet, it wouldn't surprise me :D
 
Marantz.... 2285b, 2330b, 2385, 2500, 2600.

Now they have dual secondaries, but single primaries.... in one transformer. So that almost counts.

If you're referring to dual "Transformers" not dual "Secondaries", only thing I have is the HK730. I have a Sherwood S-6040 CP which is a MOSFET DC power amp built in early 80's, not a receiver nor an integrated and it contains 2 transformers and gives about 100wpc.

Hmmm...just reread after posting this. You said "Not counting integrated nor power amps." Disregard this post.:tongue:
 
As well,
The Sanyo Plus 130 has seperate transformers.

In the "I think" category:
Akai AA-1200
Wintec 1120 (or whatever model the big one is)
The big sansui's mentioned (G-33000 for instance, indeed have dual toroidal supplies)

The Toshiba's mentioned earlier, (7100,7150) conversely in the "I dont think" category, those units have a large single toroid for the power amplifier(s) and a smaller signal power transformer for either the digital tuner portion or for perhaps the FL display or something extra or seperate, but I dont beleive they have seperate transformers in the twin-supply or dual mono intent of this thread.
 
sanyofreak is correct about the Wintec. Here's a pic

Also, the Concept 16.5

My memory might be faulty but I think my Onkyo TX-4500mkII had two transformers (like the previously mentioned 8500). I know it FELT like it did when I picked it up, but I can't remember as I only had it for a short while.
 
The Kr-9600 and the Kr-9050 did have dual transformers or thats what it says on the vintage knob.
