Date codes in early Vox Supreme amplifiers
The columns give chassis numbers; date codes of the red and (later yellow) CCL capacitors, yellow Lemco preamp capacitors, the RCA power transistors, Welwyn cement resistors; and markings in the boxes.
On the meaning of these codes, see this page. Further amps and details will be added.
Details for a couple of Super Foundation Bass amps, which have the same power section as the Supreme, are now included below. During the JMI period, the sections were stamped 100W PA SER. No. 0xxxx.
