What printing process?

OK, I answered my own question by looking at their web site, thanks Mark. I see some price examples also. What did yours cost, if you don't mind?

$59.01 front panel and $50.57 back panel. Cost increased because I infilled the milled lettering with black paint.

I think UV printing is cheaper.

Thank you guys I appreciate the comments. Doug Hoffman's little chassis are very cool. I want to built another one with EL84's.

Are you going to do anything special to ventilate the tubes. I'm kinda surprised the tubes were placed up front rather than along the rear edge of the chassis.

There is no problem with the tubes being up front, 1,000's of amps have been running with this design. I prefer your layout myself with tubes on the back of the chassis.

Just look at all the Little Walter 22w, 50w, and 80w guitar heads out there with the octal tubes up front.

Mark
