I fired up the Trainwreck Express variation today. Once the electrolytics were charged into submission, it started to work pretty well. I was quite impressed for a first time startup performance. The only shielded wire is the short input jack piece. Everything else is teflon or PVC stranded wire 22 ...

Looks very nice! Great job! If you don't mind my asking, what kind of finish did you use? I've tried spray enamel, it worked OK, but discovered it isn't very resistant to contact cleaner, oops.

Nik's layout shows the 9.1K on the recto board off the B+ line as all 4 being 3 watts which makes sense to me, being B+ dropping resistors. But what do I know?

Are you saying all the smaller resistors should be 1 watt carbon film instead of 1/2 watt?
Thanks

I just want a simple bill of materials. I can't believe this hasn't been done by now... OK, I decoded the XLS sheet in OpenOffice and then edited out the part number prefixes in Notepad for the resistors. Then I entered all the part numbers into the Mouser order form to decode the caps and finally a...

I'm still looking for a straight forward text based Express BOM. Anyone have one they can post or email me? Thanks, Rick

Perfect Doc! Thanks a whole big bunch!!

I'm wanting to build an Express, but I would like to get the chassis as close to Ken's original dimensions as possible. Any clues ar...
