Stereomour II / Stereomour II upgrades
« Last post by johnphirsch on May 15, 2025, 08:38:11 AM »Hi All,
I built my Stereomour II about a year and a half ago and have been thoroughly enjoying it. I have the DC filament, Stepped Attenuator, and Shunt Regulator upgrades, and am wondering what folks recommend for the order of upgrading. Can I do them all at once, or should I do them one at a time and in a particular order? Thanks.
John

Crack / Re: Choke specs for the Crack
« Last post by Paul Birkeland on May 15, 2025, 04:39:24 AM »It would be tough to do choke loading of the 12AU7 in the Crack without abandoning the direct coupling or having a separate power supply for the driver stage with much lower voltage.

That’s five chokes in a Crack! 😇
