This Cadco dual warmer is built from stainless steel with 2 cast iron hot plates. Made in Germany, this hot plate maintains accurate temperatures throughout the day. This item was little used and is now up for sale as I've graduated to larger capacity warming cabinets.
History: This Hickok 752 has been my trusty backup tube tester for the last two years. It works fantastic, and it rarely get used. But in the time I have had it I have ran 5AR4/6V6/6L6/6SN7/12AU7/12AX7/45/50s all thru it just to name a few.
The CQU series was designed to be a lightweight, compact plate type cylinder. The series is available in bore sizes 20mm, 25mm, 32mm, and 40mm. Auto switches can be mounted without removing mounting brackets.
