[78-L] Convert a belt drive turntable to play 78's

[Robert M. Bratcher Jr.]

Or search for a Dual 12xx (not sure of the exact model number) turntable that will play 78's then spend $50 at Garage-A-Records for the 78rpm ADC needle. Problem solved!!

I gradually spooled off what I thought to be enough tape to make the capstan drive the TT at over 78 rpm.  Then I glued the end down tight.  Checking the speed with a strobe disc, I saw I was off by a few rpm.  So I began to cut off recording tape until I reached 76 rpm (yes, 76, my choice).  Eventually I reached the length that gave me 76 rpm.  Once glued, the TT works great.  That was about 15 years ago.  Still works great!
