Yes I would like to use Macassar Ebony, it would math the wood used on my speakers. Prelim checks shows the sound to be quite nice.

Here is the back label. I made several different colors: Black Ink on Glossy Gold Foil, Back lettering on Gloss White, Blue and Orange lettering on Gloss Black and the one I finally picked was Black, Blue and Orange on Glossy Silver foil If the back plate was black then the other labels would look s...

Well This is the "Almost" finished product. Some tweaks to the front panel may be done in the future like lower and move to right the "Dynakit Stereophonic Preamplifier" text and if there is another mod that comes out that would effect the panel. https://imagizer.imageshack.com/v...

Here's an update on my progress. Closing in on finishing the project unless Erhard comes up with a filter mod and I am ready with the changes I will have to make to incorporate it. 1st up: I noticed that I had not posted the RevC Diagram: https://imagizer.imageshack.com/v2/280x200q70/923/idISwC.png ...

Well this is the kit for what I hope is the final version of my build. Everything is listed except the Front Panel and Back Label (Which is going to be another discussion when the time comes). When the Re B diagram is ready I will post it. For me a lot of the fun in doing a project is to identify wh...

Absolutely beautiful work!
