very good point. i hope this is just a quick demo setup

Tapes wont be magnetised unkess they get hit with 2x the correctivity of the tape, heqds are actually pretty tough to magnetise just randomly unless you use a magnetic screwdriver which is a nono in these machines...but otherwise, they hse solenoids for the mechanisation. Tapes can take a lot actually

Thanks

Slightly yes. But it is to the acceptable level. You can always calibrate that and it also depend on the tape as well. Regards

@@tomaszm5656 Probably the bias is not calibrated properly for the bias or the eq is off...

Hi Sound will probably depend on few more factors. Heads if they changed there was a reason, if they were worn machine was heavy used probably. It's not easy to kill those heads in my opinion and even if they have a marks of use visible they still can play good. Sound will depend also on electronics and of course on the tape quality and speed. Personally i made once a change to the heads and converted 2 track into 4 track, with a slight quality reduction but still great enough for domestic use. what could be worried in this case often people are changing heads into polished ones, so you cannot see that they are worned but they frequency response is cut off. Have a look at the rest of the machine and if it looks as not used to much or stored well you may take a risk. all depend on your abilities to repair those things.also you need to think about calibration. you can always lift frequencies on the oscilator or levels on the amps but this is for someone who know what he is doing. all depend what you need it for domestic or pro music production. Regards

Hi , I would tell they are really indestructible machines. Of course you have to find a good one at the start. If they are abused or abandoned somewhere in cold sheds for 20-30 years they are not in the best choice Even not the best ones after rebuild will be still serving you and next generation. Regards

Thanks

@@Interhomekuurne It looks like you have done a brilliant work there, but I don't understand the thing. Did you consider subtitles in english?

So why did you waist more time by writing a negative review ?? I enjoyed the video Tomasz
