another new guy warning

For what it's worth, I think the Stereomour power transformer runs cooler than the others.

I wouldn't cut it too close with the temperature. Depending on how thick the shellac...

The shellac would be a thinner coat than paint(a typical 1 lb cut of shellac is about 12% solids where paint will be in the 35-50-% solids range..higher solids = higher coating thickness) & painting seems fairly common.  I agree that any coating will insulate & raise the temp of the plate a bit.  I looked into the thermal aspects of shellac...it starts to soften at about 100 deg(F) and melts in the 160-ish deg range.  Sooo..while a tinted shellac would be perfect for adding color, it'll be too soft given the heat..oh well   There's other options.  Thanks for the measurements, they really helped.

Such a helpful discussion - I just cut my wood base and was wondering if I left enough room for expansion. 1/16 should be more than enough. thanks guys - this is a very helpful forum.

Howard,

    Well, looking at such woodworking humbles me. Whether that was furniture or stereo gear, I am speechless. The chosen woods are perfect, as are the finishes. I would say more, but am not willing to risk stumbling all over myself. Well done indeed.

Howard....very nice  work & thanks for posting the link to them.  Cocobolo? Sapele?  I've considered the all-wood option also..along with the bucket of other options I'm thinking about.  Your pics are a really valuable reference.  Your rear panels are exactly what I was thinking.

Where did you get the drilled washer-trim at the base of each tube(on the darker wood amp)?  I'm guessing you may have made them? 

Beautiful work!

WOW that is beautiful work Howard.

There is another Stereomour that Ebag4 built that has a decorative wood cover behind the tubes.  Great looking amps.

I thank the Bottleneck Gods that I got directions and don't have to know how to build an enclosure from scratch.

What considerations need to be made when adding a cover and avoiding a fire?  I bet that is a lengthy question to answer.  Another day maybe.

Great work and can't wait to hear mine!

....don't have to know how to build an enclosure from scratch.

For me, that's the easy part.  In my case the electronics assembly part will break a little new ground..

the wood is bloodwood--and here is a great site for drilled washer trim and all kinds of other goodies

Howard,

Great resource!  What they haven't got isn't worth having.

thanks..
