Presto 6N Record Cutting Lathe and 92A Amplifier

I have sold this machine. I can't make records for you. Sorry.

Back in 1996, when my first child was a baby, I hooked up with a guy at a radio station who had saved this relic in his garage for a few decades after it was removed from the studio. It's a Presto 6N record cutting lathe made c. 1950, complete with its matching 92A amplifier. I resurrected it enough to work reasonably well, and used it to make a bunch of 45 RPM double-sided dub plates for the old Wurlitzer jukebox that I run to this day in the Hotel Congress Tap Room in Tucson. I last used it about 10 years ago.

The record groove is cut with the magnetic cutting head.

The worm gear for the head drive lives in here.

The speed selection moves one of two idlers in contact with the motor.

The matching amplifier is a true boat anchor. I had to remove the busted EQ pushbuttons and Daven attenuator and replace them with modern plastic, but I still have the old parts. I drew my own schematics since the Interweb didn't have such stuff in 1996.

It has four 807 tubes in the final stage. Those are normally used for shortwave transmitting.

A view of the amplifier "top" reveals three big hunks of iron.

Back then, 33RPM records needed extra treble boost near the middle of the disk, so this equalizer gadget changed the frequency response of the system as the head moved across the disk.

The guts of the eequalizer is a big wire-wound resistor and a slide switch.
