I asume you understood the basic of cleaning axel and bearing.
O yes, but a simple explanation could be that you by changing the motor mount angle you compensated for wear on bearing and angle of the contact point of the idler wheel. What ever it was, it worked and thats the main thing with these old wonderful devises,
BTW nearly nobody here in Mexico has seen, not to speak of used , one of these RtoRs, I demonstrate it frequently, grabbing from the radio (BM 1000) and then playing from the BC showing them that Tape is engaged. I just have to get microphone, thats goanna blow them away.
Getting a B&O mic. would of course be ideal. But does any of you have a suggestion for another brand.
