    Really appreciate everyones advice -

    I mentioned in a previous thread that we are assembling our first HiFi, and the amp is going to be the 66SE -

    However i may have a miss-match on my hands in terms of speakers - The Speakers i was hoping to use are 3 OHM, which i now understand are not sufficient

    We have ordered a set of 8Ohm Speakers so we will be ok (i think)

    • Would we be ok to run the 3ohms for a few days? Is this likely to damage the Amp, which is obviously old, but in excellent condition - If there is a danger of causing damage to this, i would obviously not do it - as the 8 Ohm speakers will be here in a week or two at most - but at relatively low volume, would it be ok to use the 3 Ohms in a limited way for now?
    • The Amp has 2 tape IN and OUts - we have no intention at this time of having a Tape Deck Seperate - our main interest would be Phono (which it has dedicated), CD, Radio, and probably a Flac Compatible Media center - its also our intention to output the Television into the Amp, when watching Movies or Netflix - can we use the two tape inputs as 'extra Aux' inputs? Im only learning about this arena - and i know with some degree of certainty that one should never use the PHONO in, for anything other than Phono (this is due to the pre-amp? i think?) - are there any similar restrictions on the TAPE inputs? The outputs are inconsequential, as we wont be recording to anything

    Really appreciate this forum, im new - im learning a lot, and making mistakes as i go - part of the process i guess!!

    Most hifi speakers are 4-8 Ohms. What speaker model is this 3 ohm one? Your Marantz amp is rated 70w for 4 ohm loads. 3ohm isn't too much lower then that. Short answer is that you're unlikely damage your amp/speakers. Just don't play the speakers too loud. At louder levels you might get the amp heating up or it could blow the speakers.

    You can use the tape inputs for whatever line level output device you have. CD/DVD/TV/Streamer. etc The reason you can't run a record player through those is that output of a record player is much lower then a line level, so you need a pre-amp to increase that phono output up to line level
