The problem with this model was in fact those glass heads. They were great for mechanical wear BUT the composition of the heads made them very unstable at higher frequencies. I tried to have them re adjusted but no good. The higher freq's were missing. anything above say 9 K were gone. Very troubling. I had heard they some people replaced those heads with laminated heads giving much better performance. I was so upset with this model, I finally got a Technics US 1500 US 1/2 track machine to make my master tapes. The response on the US 1500 was 20 to 20K. BTW, the 7010 was heavy 70 some pounds.

Hi,
You might be right about that as mine was having some problems when I was recording on it and yes they are very heavy.
