H/K 330C question

I'm Freaking Out Mannnn!

Well I hit a major Karma wave today. A guy at work, out of the blue, brought in a Pioneer SX-580 and an H/K 330C and gave them to me for free. He overheard me talking to someone about getting into vintage 70's. I offered him some bucks, but he wouldn't except.

They're in perfect condition...in fact I've never owned any vintage receivers that didn't have amp thump upon power off/on, these don't. Well I've arranged, with another AK member to trade the Pioneer for some stuff I need.

Upon hooking up the H/K everything worked fine, but needed deoxit in the pots (no biggie). Here's my question (finally I know right?): after cracking the case I noticed the t-former didn't match the one in the manual I had. Then I noticed a distinct switch (SW201) on the pc board, which didn't match the manual picture. Is this just a multi voltage unit? How else does this 330C differ from others?

Thanks for the replies.

According to the service manual some models have a rotary switch to select different input voltages.That would also explain the difference in the transformer appearance ie. 3 or 4 additional wires all going to that switch.
 
I think you may be correct. I missed the rotary, I meant an actual toogle switch on the opposite side of unit of the t-former.

Is that toggle switch nearest to the the tuner? And is it marked 50--75 us ( as in microseconds). Should be in 75 position for operation in the US....(deemphasis switch. 50µs for Europe, 75µs for the US)
