Hi, all,
at the moment I'm restoring a Mills Studio amplifier.
(Automatic Phonograph)
Almost all pre-war Mills amplifiers are using a company-code
for there amplifier-components,
like resistors, capacitors, tubes etc.
The all are numbered with "MCP" and then a number,
excample: MCP-1669 is a 5Z3.
Is there a conversion-list for those pre-war Mills parts ??

Best regards,
Jo van Dongen

Hi, Jo
Give the other tubes in the lineup, and let's see if we can find something built pre-war that will have a similar schematic. A 5Z3 is a pretty powerful rectifier tube, what are the output tubes?
