Default Re: Grundig TK 146 Reel to Reel Check Out

Replaced the badly cracked tape counter drive belt. Original round section belt was around 1.8mm x 80mm ID which was fairly slack, used a square section 1.7mm x 70mm which is working well.

I had the same problem with mine, using the 2mm 83mm replacement belt from a pack of three bought online, the counter belt was too loose.

I tried a few other belts I had and discovered that the machine is quite sensitive to counter belt tension, if it is too tight the RH spool does not move left enough during FF. Eventually found a suitable belt that worked albeit smaller cross section. There is little drive load on this belt so it should be durable enough

Best Regards
