Very confusing Terry - Why not list the kit you are using, spell out clearly what you need it to do, and there will be plenty of helpful responses (and some piss-taking) - anyone trying to answer your original post could just make things worse through misunderstanding!

The Music Angel is a valve amp. Don't power this up unless it is connected to speakers. If you do power it without speakers you risk damaging it. It seems that there are several versions of this and that there are also quite a few out there which have been modified by enthusiasts -800mkiii.html'>http://taooftubes.blogspot.co.uk/2012/01/music-angel- xD -800mkiii.html. But assuming it is in original condition and similar to the circuit shown on that webpage then it will have an input impedance of 200k and should therefore be suitable for feeding from a phono splitter. However it will be earthed (at least I very much hope it will !). So if the Teac is also earthed then going down the phono splitter route could result in ground loop hum.

The Teac is a solid state amp. You can run this powered with no speakers or headphones connected if you want - this should not harm it. So if you want to take the tape out option to feed the Music Angel and if this requires you to power the Teac then you could. But you still run the risk of ground loop hum (Music Angel will be earthed through its mains lead, Teac might be earthed through its mains lead, both amps will be connected together with a signal ground connection through the interconnect's screen).

As far as the hum is concerned I think you'll have to suck it and see.

:^ thank you very much 4 that if one or booth the amps are not earthed which one should I add a earth to ?
Both.

Hum is annoying. Electrocution is fatal.

Unless properly double insulated, anything plugged into the mains should have its chassis earthed. ANY vale amp should have its chassis earthed, and personally I prefer to case earth everything, regardless of whether or not it's double insulated. Better safe than sorry when it comes to mains, but for tube amps it's essential. There are serious voltages flying about inside and with some amps the construction isn't that wonderful.

Something not right here.

The questions do not seem to have a logical thread.

or are the meds wearing off.

Put down the soldering iron and reed a book.

ok vavle amp not eathed ...
That doesn't sound good. Does it have a three-core mains cable ? If it does then the earth core in the cable should be properly electrically bonded to the chassis, and there are other rules about how other metal parts should be bonded together. But sorting out any problems with this is not a business for amateurs. If the amp only has a two-core mains cable then it is, as Rabski said earlier, supposed to be double-insulated. Achieving that in a valve amp is difficult, but maybe this manufacturer has managed it ? Again though deciding whether this has been done properly is beyond an amateur. It will need to be physically checked over by someone who's been properly trained and who is insured, just in case a mistake he makes harms someone or burns their house down.
