I also remember never going near these duplication operations without full sets of heads, guides, pinch rollers, and a BUNCH of additional mechanical items. The whole process took 2-4 days at least, depending on how many hours / week were put on the machines and how many there were.. Bias settings were painful in particular.

It runs and the meters move but nothing gets recorded on the two copies... Free to a good home (plus shipping)! This was the best in-cassette duplicator as it ran 8x insead of 16x or higher speed... <L> On Jan 13, 2011, at 10:09 PM, Dan Nelson wrote: You would be amazed at the number of Telex 300 Cassette duplicators banging out the cheap n dirty CC's. They used in cassette duplication at 15/30 ips and could duplicate from cassette or 1/4 inch reel masters, 2 or 4 tracks at same pass. One company i service had 30 slaves running 16hrs/6 days week. I would buy heads 100 at a time from Nortronics... complete replacement every couple of months with all the associated allignment, bias and drive adjustments was a 2 day pain in the toosh. I for one am glad this era is over, but at the time the money was good. dnelson
