I, being a geek on a tube forum, would go for covering some of the wiring and transformers, and try to make it look good somewhat exposed. It could be difficult, though!

I built a chipamp a few months ago, and just finished its chassis last night.. I'm really happy w/ how it came out, so will post a pic... The wood is a very nice hardwood, and the photo does not do it justice.. plus it clashes w/ my wood floor, but you get the idea...

I'll throw in a PP tube amp I built, too, just to keep it somewhat on topic 🙂

OSWALDSMILLAUDIO - Tasting 2004

Some wackos there... and some original looks.
I wonder about this PS... a 2a3 amp, I don't get it.

Watch it, some of those guys are friends of mine.. 😀

OT:
I never got to go, (personal circumstances prevented it) but have organized the local ersatz equivalent for some years now. Some of the guys have a great sense of aesthetics, and unfortunately some really don't. (or worse.. 😱 )

Incidentally the gear I have heard in most cases will blow quite expensive high end commercial product out of the water. So aspersions aside appearance isn't necessarily the most important aspect to most builders.

The mill meet was a pretty big deal and a lot of work for the organizer. I have been involved in several not so small local events in the past, and next week- end host one at my place for about 15 invitees from our local tube audio group. It's a lot of fun and we always make sure to invite a few unsuspecting souls who usually are fully indoctrinated by the end of the day in the arcane ways of tube audio. Most of our members have come to favor SE in various flavors with HE speaker systems. (In my case from Magnepans to Ultraflex/Onken)

Olive green ? Ah......Nein. Black on trannies looks more beastly...next theme: I notice loudspeakers unfinished with chicken wire grill: ? Yup I've done this my bass stack but you need to apply thickish paint to damp and securely clamp to avoid buzzes. 2x15" 8Cuft (200Lit) floor loaded reflex system. For domestic use simply cover grills with black drape.

oh yes something i forgot

the lower doors are the backs of the speaker cabs on alot of their stuff.
so as you open the doors the speaker cabs hang outside the main cabinet on each side.
the wife will love them and clean them and let you have them in the living room
 
This is my 5th diy amp, It's a 2A3 stereo with a tube voltage regulator.

It's my diy version of a Yamamoto!

I just listed it on ebay.... selling to support my hobby (addiction) of building amps!

Being that I'm not much of a carpenter, nor do I have all sorts of fancy equipment, I go for "functional ugly".

For both projects, I went for wood for the main cabinet. All the circuitry is built on #16 steel sheet. It has strength, is easy to work with, and takes paint very well. I used red iron oxide primer (Rustoleum) and Rustoleum enamel. In order to get a durable paint job (these projects were completed in 2005 and 2007) it is necessary to wash the unfinished steel with plenty of soap and hot water to eliminate all traces of oil and grease, which is definitely present from both the cutting at the sheet metal shop, and the Greenlee dies used to make holes. Then wash down with acetone to prepare the surface. Once that's done, don't touch! If you get rid of all oil and grease, the paint doesn't bubble up and peel.

For the Vixen (807 based stereo amp) I used poplar, primed and painted with high gloss latex. A good paint job covers a multitude of woodworking "sins".

The Le Renard (6BQ6GA based monoblock) cabinet is red oak, sanded smooth with fine sand paper, and then given several coats of Formbee's oil to bring out the shine. To set the bias, I found this nice, retro-looking, aircraft style 100uA meter. Included is a small toggle switch to switch between finals. Since this project runs both the HV and heaters from the same power xfmr, I didn't bother to include a panel light, since the voltage reference tube serves the same purpose anyway.
