MH's ideal coil and voltage question

The DM CD-60 sounds pretty damn sweet.

Thanks Poynt!

Our tube series was 30T, 60T, and 120T and ended up relabeled and repackaged as the DM CD series with a few minor changes. The solid state models were treated in a similar fashion plus many models were dropped. JMF was vertically integrated in that we had our own tool and die shop to make tooling for the metal fabrication shop, complete pcb fabrication including cnc drilling with PTH and gold plating lines, transformer winding, wood working, and of course assembly lines plus wave soldering, etc. We did everything in-house except injection molding in an effort to control quality.

As time went on, DM's people lost control of some of the processes which was the beginning of the end. I have lost track of where his amps are built today.

Sorry to take this thread so far off course!

The amplifiers are now made in China of course.

In this interview Markley says he designed the CD60 around 1985.
